Color Decision Guide
The short answer
For DovEggs clear moissanite: our hand-pick practice means our DEF-graded inventory is actually D color and our GHI-graded inventory is actually E–F color. We don't carry F or below in standard inventory unless specially requested. Whichever tier you pick, you're getting better than the label suggests.
For DovEggs Boutique lab diamond: we grow and cut every stone ourselves, focused on exquisite quality, fancy cuts, and a curated set of value-retaining colors (currently including pale pink, vivid green, and vivid blue — we adjust based on market demand). Limited pieces; each one is held to our internal standards before listing.
For DovEggs Essential and Lab Diamond Group: Essential stones are also grown and cut by us in standard cuts; Group stones come from our partner labs and give you access to 10,000+ certified lab diamonds across every color, shape, and cut on the market. We price match any Group stone listed cheaper at another vendor.
For DovEggs colored moissanite: our specialty colors include Peacock Blue (most popular), Twilight Blue and Stardust Grey (DovEggs-developed and community-named), Smokey Sparks Grey (limited inventory — ask before ordering), Champagne, and our rotating Accident Colors collection.
For DovEggs lab-grown colored gemstones: sapphire (deep royal blue, AAAAA quality), ruby (pigeon blood / Burma red), and emerald (Zambia green with bluish overtone). All available in our full cut catalog — including Crown Arrow™, Sakura, Pixel™, and our antique cuts.
Everything below is the long answer.
Key takeaways
- Color grading depends on the material. Lab diamonds use the GIA D–Z scale, graded one stone at a time. DovEggs clear moissanite uses our internal DEF / GHI tiers, hand-picked. Colored stones (moissanite, colored lab diamond, colored gems) are evaluated on hue, saturation, and tone — not against D–Z.
- Every stone we sell is lab grown. DovEggs is a 100% lab-grown brand for environmental reasons. We do not carry mined diamonds, mined sapphires, mined rubies, or mined emeralds.
- DovEggs clear moissanite is over-delivered. DEF tier = actually D; GHI tier = actually E–F. The label is conservative; the stone is better.
- DovEggs Boutique lab diamonds are grown and cut in-house. Limited pieces, fancy cuts (Modified Ashoka, OEC, OMC, Rose, Crown Arrow™, Modified Sakura — and more as our cutting catalog evolves into lab diamond), curated value-retaining colors.
- Lab Diamond Group gives you the entire market. 10,000+ certified stones, every color and cut. We price match; we'll never let a Group stone be cheaper at another vendor than at DovEggs.
- Colored moissanite is grown, never coated. Every colored stone retains its color indefinitely because the color is intrinsic to the material.
- Setting metal masks or reveals warmth. Yellow and rose gold mask faint warmth; white metals reveal it. Match material grade to setting metal for best value.
- Any DovEggs setting works with any DovEggs stone. Whether you choose moissanite, Boutique lab diamond, Essential, Group, or a colored gemstone — every stone we sell is compatible with our semi-mount catalog.
Section 1: The three materials
DovEggs sells three categories of center stone, each with its own approach to color. Knowing which material you want is the first decision; color choice then becomes much simpler.
Moissanite
Lab-grown silicon carbide. Higher dispersion than diamond (more rainbow fire), higher refractive index (more brilliance), Mohs hardness 9.25 (just below diamond). DovEggs has focused on moissanite for 11 years and we grow and cut every stone we sell — both clear and colored.
Pricing scales relatively flat with carat weight, which makes moissanite particularly attractive at larger sizes (2.5ct and above).
Lab-grown diamond
Lab-grown carbon, chemically and optically identical to mined diamond. Mohs hardness 10. Available in three DovEggs product lines:
DovEggs Boutique — grown and cut by DovEggs. Focused on exquisite quality, fancy cuts (Modified Ashoka, OEC, OMC, Rose, Crown Arrow™, Modified Sakura), and curated value-retaining colors. Limited pieces. As lab diamond costs continue to fall, more of our proprietary cuts (Astro, Nova) will move into Boutique production.
DovEggs Essential — grown and cut by DovEggs. Standard modern cuts (H&A round, oval, cushion, etc.). Held to the same growth and cutting standards as Boutique, but at standard cut configurations rather than fancy.
Lab Diamond Group — sourced through our partner labs. Over 10,000 certified stones available, covering every color, shape, and cut on the market. Priced individually and price-matched against any other vendor.
For more on lab-grown diamond fundamentals (how they're grown, certification, comparison with mined), see our Lab Grown Diamonds Guide.
Lab-grown colored gemstones
Lab-grown sapphire, ruby, and emerald. Same chemical composition and physical properties as their natural counterparts — only mass spectrometers can tell them apart from mined stones. Hardness 9 for sapphire and ruby, 8 for emerald.
DovEggs colored gems are intrinsically colored: Zambia green emerald, pigeon blood ruby, deep royal blue sapphire. Quality at AAAAA grade (sapphire), pigeon blood / Burma red (ruby — the rarest red category), and deep saturation (emerald with characteristic bluish overtone).
Critically, every DovEggs colored gem can be cut in any cut from our catalog — Crown Arrow™, Pixel™, Sakura, Astro, Nova, Empress, Modified Ashoka, Modified Sakura, OEC, OMC, Rose, Portuguese, plus all standard cuts. This is unique to DovEggs; most colored-gem vendors offer a small subset of standard cuts.
Choosing between the three materials
The simplest decision tree:
- Want a classic white stone, traditional look? Lab diamond (Boutique for fancy cut, Essential for standard, Group for maximum selection and price match).
- Want maximum sparkle and fire, flexible with rainbow flashes? Moissanite.
- Want a stone in a specific color (blue, red, green) with traditional gem identity? Lab-grown colored gem.
- Want a non-traditional color with moissanite's brilliance? Colored moissanite (Peacock, Twilight, Stardust Grey, etc.).
- Want to be unique and value-conscious? Boutique colored lab diamond (pale pink, vivid green, vivid blue).
Most of our buyers ultimately combine two or more — for example, a clear moissanite center with colored side stones, or a colored gem solitaire with a clear moissanite eternity band. Our team is happy to consult on material combinations.
Section 2: How DovEggs grades clear moissanite
For 11 years our team has graded clear moissanite stone by stone, by hand. Every piece is individually evaluated under controlled lighting against master comparison stones before it's listed. Stones that don't meet our internal standards are returned to the cutter.
How our tiers actually work
Our two clear moissanite tiers are DEF and GHI — but the stones inside each tier consistently exceed those grades:
- DEF tier: every stone is D color. We don't blend D, E, and F within this tier; we hold the entire tier to D.
- GHI tier: every stone is E or F color. The "GHI" label is conservative — in practice, our GHI inventory tests at E–F under master comparison.
Customers who pay GHI pricing receive what most vendors would sell as DEF. Customers who pay DEF pricing receive top-of-colorless D.
What we don't carry
We don't stock F-or-below in standard inventory. If a stone tests at G or below in our hand-pick process, it doesn't enter our regular tiers. The only exception is special order — typically buyers wanting a specific vintage aesthetic. We also don't carry K, L, or M moissanite (older moissanite from the early 2000s could test in this range; modern moissanite is overwhelmingly E–F or better).
Cut and color interaction
Color appearance is partially driven by cut. Crushed ice and other modified-brilliant cuts read slightly warmer than H&A at the same actual color grade, because the fragmented faceting pattern lets more light penetrate the body of the stone before returning to the eye.
If you're choosing a non-H&A cut and color is a high priority, request a video before committing — email inquiry@doveggs-seattle.com and we'll send 360° rotating footage in the lighting condition of your choice.
Why this matters for buyers
Three practical implications:
- You don't need to upgrade beyond GHI to get colorless results. GHI delivers what most vendors call DEF. Many of our long-term customers buy GHI for everything.
- The DEF premium buys certification, not a visible difference. D vs. E vs. F is invisible to the eye in any normal lighting. The DEF tier exists for buyers who want top-tier paperwork or peace of mind.
- What you see is what you get. Hand-picking means the stone you see is the stone you receive. We don't substitute, we don't grade-creep, and we don't run different standards for different price points.
Section 3: How lab diamond color is graded
Lab diamonds use the same GIA D–Z scale as mined diamonds, graded individually per stone. Across all three of our lab diamond product lines (Boutique, Essential, Group), color is reported per-stone with certification from IGI or GIA.
The scale breaks into the same five practical tiers as mined diamond:
Colorless (D, E, F). No detectable color even when set face-down on a white card next to a master stone. The price difference between D and F can be 8–15% — almost entirely a paper distinction visually.
Near-colorless (G, H, I, J). Faint warmth detectable only under controlled comparison; not visible face-up to most viewers. This tier is where most informed buyers find the best value, especially when paired with yellow or rose gold settings.
Faint (K, L, M). Visible warmth in some lighting, particularly against white metals. Looks beautiful in yellow or rose gold settings. Significantly less expensive than higher grades.
Very Light (N–R). Clear yellow tint visible face-up. Rare in modern engagement rings.
Light (S–Z). Distinct yellow color. This range overlaps with what's sold as "fancy yellow" diamond.
For Boutique lab diamond inventory, we typically focus on D–G clear stones plus our curated colored lineup. For Essential lab diamond, we stock D–K depending on demand. For Lab Diamond Group, every grade D–Z is available across our 10,000+ partner-lab inventory.
For more on lab diamond fundamentals, see our Lab Grown Diamonds Guide.
Section 4: DovEggs Boutique colored lab diamonds
Beyond clear, our Boutique line features a curated set of fancy colors — chosen because they're both visually striking and value-retaining. The current lineup includes pale pink, vivid green, and vivid blue. We adjust this lineup based on market demand and our growth capacity, so additional colors may appear over time.
What "Boutique" means for color
Three commitments that define our Boutique colored lab diamonds:
We grow them ourselves. Every Boutique colored lab diamond is grown in-house with chemistry tuned for the target color. We don't buy and resell colored rough; we control the entire process.
We cut them ourselves. Boutique stones are cut in our specialty cuts — currently Modified Ashoka (more like an Ashoka silhouette than a Criss cut, with the pillow shape and extra brilliant facets), Old European Cut (OEC), Old Mine Cut (OMC), Rose Cut, Crown Arrow™, and Modified Sakura. As lab diamond costs continue to fall, we'll add Astro, Nova, and other cuts to the Boutique cut catalog.
Limited pieces, individual evaluation. Each Boutique stone is graded individually for color saturation, hue purity, and clarity (typically VVS to VS). We don't run batch grading; the stone you see is the stone you get.
The current colored lineup
Pale pink Boutique lab diamond. Soft, romantic pinks ranging from blush-pale to richer rose. Holds value well — pink lab diamonds have one of the strongest secondary markets among fancy colors. Pairs particularly well with rose gold (color enhanced) and white gold (color contrast).
Vivid green Boutique lab diamond. Saturated green ranging from spring grass to forest. Vivid green is the rarest naturally-occurring fancy color in mined diamonds (which is why historical pieces are extremely valuable); lab-grown vivid green delivers the same visual character at radically more accessible pricing. Pairs beautifully with white gold and yellow gold.
Vivid blue Boutique lab diamond. Rich, saturated blue — like a deep sapphire or the iconic blue of historic fancy-color diamonds. Cool-toned and dramatic. Best in white gold or platinum settings, where the cool metal reinforces the blue.
Why we curate
We curate the Boutique colored lineup rather than offering every fancy color because:
- Each color has its own growth chemistry. Producing vivid blue requires different conditions than producing pale pink. Mastering each color takes time.
- We focus on value-retaining colors. Pink, green, and blue have the strongest fancy-color markets. They're not just aesthetically distinctive — they hold their value over time.
- Limited pieces means individual attention. Every Boutique stone gets hand evaluation. If we expanded to every possible color, we'd lose that level of care.
How Boutique colored lab diamond compares to colored moissanite
Both are beautiful; they serve different buyers.
Boutique colored lab diamond has the optical character of diamond — clear, clean, "depth" — with the value-retention curve of fancy colored diamond. It's chosen by buyers who want fancy color with traditional gem identity and resale strength.
Colored moissanite has higher dispersion (more rainbow fire) and more saturated jewel-tone effects. The color often reads more dramatic under light. It's chosen by buyers who want the most visually expressive colored stone, less concerned with market resale.
Many of our long-term customers own both — for example, a Boutique vivid blue lab diamond ring on one hand and a Peacock Blue moissanite ring on the other.
Pricing for Boutique colored lab diamond
Pricing is per-stone, not per-tier, because each Boutique colored stone is hand-evaluated. Generally:
- Pale pink runs at the highest premium of the current lineup, reflecting fancy-color market pricing for pink.
- Vivid green and vivid blue run at moderate premiums, both significantly less than mined-diamond equivalents.
- All Boutique colored lab diamonds are dramatically more affordable than equivalent mined fancy color — that's the entire point of lab grown becoming our core value: luxury jewelry for all, not just the wealthy few.
Email inquiry@doveggs-seattle.com to inquire about current Boutique colored inventory or to start a custom order.
Section 5: Lab Diamond Group
The Lab Diamond Group is our partnership with multiple specialized labs, giving you access to over 10,000 certified lab diamonds across every color, shape, cut, and quality combination available in the global market.
What the Group is for
Group is for buyers who want maximum selection rather than the curated fancy-cut focus of Boutique. If you have a very specific spec in mind — a 2.13ct G-color VS1 cushion, or a 1.45ct K-color radiant in a yellow gold halo — Group is where you'll find it.
Group is also where you'll find:
- Lab diamonds in every fancy color (yellow, pink, blue, green, brown, gray, black) at every saturation level.
- Lab diamonds in every shape, including less-common shapes Boutique doesn't currently offer.
- Lab diamonds at every quality combination, from VVS1/D top-tier to SI2/M value-tier.
- Lab diamonds at every carat size, including very large stones (5ct+, sometimes 10ct+) that are difficult to source elsewhere.
Price match guarantee
Lab Diamond Group is price-matched. If you find the same Group stone listed cheaper at another reputable vendor, we'll match the price. This is one of our core commitments — we won't let our access to the global lab diamond inventory translate into uncompetitive pricing.
To request a price match, email inquiry@doveggs-seattle.com with the competing listing's URL and stone certification details.
How Group inventory rotates
Because Group inventory comes from multiple partner labs, it changes daily. A specific stone you saw last week may be sold; new stones come in continuously. If you have specific specifications, our team can set up a notification when matching stones arrive — email us with your target specs (carat range, color range, clarity range, shape, cut grade) and we'll watch the inventory feed for you.
Group + DovEggs settings
Every Group stone — like every Essential, every Boutique, and every moissanite — works with our full semi-mount setting catalog. You don't lose access to our settings by choosing Group. Whether you pick a $1,200 Group stone or a $20,000 Boutique stone, the same DovEggs settings, warranty, and lifetime maintenance apply.
This is one of the reasons many customers choose to buy stones from us even when stone-only marketplaces might quote slightly different prices — our setting quality, lifetime warranty, and customer service are part of the total package.
Section 6: DovEggs colored moissanite
Beyond clear, we offer six signature moissanite colors — each with its own loyal community following and its own quality story. All six share three commitments unique to DovEggs:
We never coat. We only grow. Every colored moissanite stone we sell is grown to its color from raw material. The color is intrinsic to the stone, present at every depth, and stable indefinitely. Coated stones (sold by some vendors at lower prices) develop their color from a thin surface layer that wears off over years; ours never do.
We cut every colored moissanite in-house. Colored moissanite cutting is harder than clear cutting — the color body affects how light moves through the stone. Our cutters have spent years developing facet patterns specifically for our colored materials.
Eleven years of R&D in colored moissanite. Twilight Blue, Stardust Grey, and Smokey Sparks Grey are colors DovEggs developed and our community named. They didn't exist in the moissanite market before us.
Peacock Blue (our most popular specialty color)
A deep teal-blue with shifting green undertones — the stone reads differently as the angle changes, evoking the iridescence of actual peacock feathers. In motion, Peacock Blue produces flashes of green, blue, and a touch of violet over a rich saturated body color.
Peacock Blue pairs beautifully with both white metals (which sharpen the blue) and yellow gold (which brings out the green undertones). It looks particularly striking in our Pixel Cut™ — geometric facets concentrate the color into clean blocks of teal that read almost gem-like.
Best for: statement engagement rings, anniversary gifts, anyone drawn to sapphire but wanting moissanite's brilliance; non-traditional weddings; jewel-tone enthusiasts.
Twilight Blue (DovEggs proprietary)
A deep, jewel-toned blue ranging from soft sky blue in smaller stones to richer, more saturated blue in larger ones. Underneath the color, the natural dispersion of moissanite is preserved — Twilight Blue produces flashes of rainbow fire over a blue base.
DovEggs developed this color and our community named it. The growth chemistry is difficult and yields are low, which is why Twilight Blue carries a premium over Peacock Blue and Champagne. It pairs beautifully with Nova cut (which amplifies fire under the blue body) and with H&A round (a classic outline carrying an unexpected color).
Best for: non-traditional engagement rings, alternative weddings, anniversary upgrades; buyers who already know they want something genuinely rare.
Stardust Grey (DovEggs proprietary)
A subtle smoky grey with silver undertones — deliberately understated. Stardust Grey reads as quiet sophistication rather than jewel-tone drama. In dim light, the stone takes on a slightly mysterious cast; in bright light, the grey reveals more silver.
The growth process is even more delicate than Twilight Blue's — small variations in growth conditions shift the grey toward green, brown, or blue, and only stones in the correct silver-grey window pass our standards. There isn't a cut Stardust Grey can't pull off (a phrase we hear repeatedly from our community); it pairs beautifully with our Sakura Cut and is especially loved in Rose Cut.
Best for: minimalist aesthetics, alternative weddings; designers, architects, and creative-field buyers; buyers who own little other diamond or moissanite jewelry and want their one piece to be quietly distinctive.
Smokey Sparks Grey (limited inventory — ask before ordering)
A blue-grey moissanite with dramatic chameleon properties — the stone shifts visibly between cool blue undertones and warm grey depending on light source. Many community members describe it as a "perfect mixture of grey blue" that goes well with all metal tones.
Important availability note: Smokey Sparks Grey has raw stone supply limitations, so it's only available in certain sizes and shapes. Email inquiry@doveggs-seattle.com before ordering to check current availability for your target size and shape. We've had this color for years and it has a devoted cult following — but we cut what we have, and what we have varies.
Best for: existing DovEggs collectors, buyers who want a chameleon stone, lovers of the original moissanite "old school" specialty colors.
Champagne moissanite
A warm, golden-honey hue — somewhere between cognac and pale champagne. The color is consistent throughout the stone (no zoning) and saturates more visibly in larger sizes. Champagne moissanite has the same brilliance and fire as colorless moissanite; the only difference is body color.
Champagne pairs beautifully with yellow gold and rose gold. It's the most accessible of our specialty colors — easier to grow than the proprietary blues and greys, and priced closer to clear colorless moissanite. Our community especially loves Champagne in Nova cut for its rainbow flashes against the warm body.
Best for: vintage and antique aesthetics, warm-toned wardrobes, autumn-themed weddings; anyone drawn to yellow diamond at moissanite pricing.
Accident Colors (rotating limited collection)
We have a dedicated Accident Colors collection — moissanite stones that emerge accidentally during the growth of our other proprietary colors. Because the color in these stones is unstable (small variations in growth conditions produce inconsistent results), accident colors can't be permanent product offerings. Instead, when an accidental batch occurs, we cut the rough into popular shapes and our most-loved cuts, and release the result as a limited drop.
Examples of accident colors that have appeared in our inventory over the years:
- Pale yellow / canary — yellow body with rainbow fire, often described by community as "looks like canary diamond, only with more fire."
- Dark green / black-green — deep mysterious green that reveals rainbow flashes when light hits it. One of our community's all-time favorites.
- Ocean blue — a soft blue sometimes described as "ocean."
- Blue tint — a delicate blue undertone.
- Smokey blue-grey variations — the dramatic chameleon variations occasionally produce one-off stones.
Why DovEggs community loves Accident Colors: Each piece is genuinely one-of-a-kind. Once a batch sells out, that exact color/cut combination won't return — the chemistry can't be reliably reproduced. Community members watch for accident color drops the way collectors watch limited art releases.
To follow accident color drops, subscribe to our community list at marketing@doveggs-seattle.com or join our Facebook community for early access.
Pricing for colored moissanite
Roughly, in ascending order:
- Champagne — comparable to clear colorless moissanite of the same size and cut.
- Peacock Blue — moderate premium over clear (typically 15–25%).
- Stardust Grey — premium over Peacock Blue, due to rarity and growth difficulty.
- Twilight Blue — comparable to Stardust Grey or slightly higher.
- Smokey Sparks Grey — varies significantly with availability; ask for current pricing.
- Accident Colors — variable per batch; usually priced as one-of-a-kind specialty.
All colored moissanite is priced individually rather than from a fixed scale.
Section 7: DovEggs colored gemstones
We also grow lab-created sapphire, ruby, and emerald — a category many lab-grown brands skip but that we've invested in for our customers seeking traditional colored-gem identity.
What "lab-grown gemstone" means
DovEggs lab-grown colored gemstones are grown by simulating in a laboratory the natural formation of these gem materials. They contain the same chemical compositions and physical properties as natural sapphire, ruby, and emerald — and only mass spectrometers can distinguish them from mined stones.
We use the best cosolvent technology in the market for our gem growth. Mohs hardness ratings match natural counterparts: 9 for sapphire and ruby, 8 for emerald — the same lifetime durability as mined gems.
Clarity standard: VVS1–VVS2 across our colored gem inventory.
Sapphire (deep royal blue, AAAAA quality)
Our DovEggs sapphires are intense, deep royal blue — what the gem trade calls AAAAA quality, the top sapphire color category. The color is saturated and even, without the green or grey overtones common in lower-quality blue sapphire.
In white gold or platinum settings, our sapphires read as classic high-jewelry blue — comparable in visual character to top-tier Kashmir or Burma natural sapphire, at radically more accessible pricing.
Best for: classic colored-stone engagement rings, September birthstones, anyone drawn to the timeless blue-stone look; alternative wedding sets; "something blue" rings.
Ruby (pigeon blood / Burma red)
Our rubies are pigeon blood red — also called Burma red, the rarest red category in natural ruby. The color is deep, slightly fluorescent, and warm (with no orange or pink shift). In natural mined form, pigeon-blood rubies command extreme premiums; in our lab-grown form, the same color is accessible.
Best in yellow or rose gold (warm metal harmonizes with warm stone) and in white gold settings (cool metal creates dramatic contrast). Looks particularly stunning in Modified Ashoka and Empress cuts in our catalog.
Best for: statement engagement rings; July birthstones; anyone drawn to red gemstone identity; vintage-inspired pieces.
Emerald (Zambia green with bluish overtone)
Our emeralds match what the trade calls Zambia green — a deep green hue with a slight bluish overtone, consistent saturation, and superior clarity (VVS1–VVS2, vs. the heavily-included natural emerald market norm). The color is the classic "emerald green" most people picture when they hear the word.
Pairs beautifully with yellow gold (warm complement) and white gold (cool contrast). Particularly striking in Modified Sakura, emerald cut (the obvious classic), and Rose Cut for vintage character.
Best for: colored-stone engagement rings; May birthstones; vintage and Art Deco aesthetics; anyone drawn to green-stone identity.
Cut and color: the DovEggs differentiator
Every colored gem we sell can be cut in any cut from our catalog. This is unique to DovEggs and worth explaining:
Most colored-gem vendors offer standard cuts only — round, oval, cushion, emerald cut, princess. Their cutters are set up for a small number of standard shapes, and venturing into specialty cuts (Crown Arrow™, Pixel™, Sakura, Rose, OEC, Portuguese, etc.) is uneconomical at their scale.
Because DovEggs grows our own gem material and cuts it in-house — and because we already operate the cutting infrastructure for our moissanite specialty cuts — we can produce a Sakura sapphire, a Pixel ruby, or a Crown Arrow emerald with the same precision as our moissanite specialty cuts.
This opens up combinations no other jeweler offers:
- Modified Sakura emerald — Zambia green in our flower-petal facet pattern.
- Pixel™ sapphire — geometric facets in deep royal blue.
- Rose-cut ruby — pigeon blood in vintage flat-back domed silhouette.
- Crown Arrow™ sapphire — our signature arrow pattern in royal blue.
- OEC ruby — antique European faceting in pigeon blood.
Email inquiry@doveggs-seattle.com to discuss cut + colored gem combinations. Custom cut+gem combinations typically run 4–8 weeks lead time.
Sizing for colored gemstones
Sizing for our colored gems matches our moissanite size chart. Approximate face-up dimensions:
| Carat | Round | Oval | Elongated Oval | Cushion |
|---|---|---|---|---|
| 1 ct | 6.5 mm | 5×7 | 5×8 | 6×6 |
| 1.5 ct | 7.5 mm | 6×8 | 5.5×8.5 | 7×7 |
| 2 ct | 8 mm | 7×9 | 6×9 | 7.5×7.5 |
| 3 ct | 9 mm | 8×10 | 7×11 | 8.5×8.5 |
| 4 ct | 10 mm | 8×11 | 7.5×11.5 | 9.5×9.5 |
| 5 ct | 11 mm | 9×11 | 8×12 | 10×10 |
For full size details across all shapes, see the sizing chart on each product page.
Section 8: How setting metal affects perceived color
Where your stone is set changes how its color reads to the eye — and this applies across all materials.
Platinum and white gold (cool metals). Visually neutral white. Any warmth in the stone is highlighted against the cool metal. If your stone is G or below in lab diamond, white metal makes warmth more visible. For colored stones, white metal generally creates contrast — beautiful for blue, cool, and green stones; can feel cold against warm stones like ruby or champagne.
Yellow gold (warm metal). Masks warmth. A J–K lab diamond in yellow gold can look face-up identical to an F–G stone in white gold. This is the single biggest value lever in clear-stone buying. For colored stones: yellow gold harmonizes with warm tones (champagne, ruby, pink) and creates warm contrast against cool tones (blue, green, grey).
Rose gold (warm, pink-shifted). Masks faint warmth similar to yellow gold but adds a pink reflection. For specialty colors: rose gold flatters Champagne and pink, contrasts beautifully with Twilight Blue and Peacock Blue, complicates Stardust Grey (the pink can fight the grey).
Mixed metals. Two-tone settings split the difference. Useful for buyers who want flexibility but adds complexity. Our team is happy to consult on metal-color combinations as part of any custom design process.
Section 9: How lighting affects color
The lighting you wear your ring in matters more than most buyers realize. This applies across all materials but matters most for colored stones, where lighting can shift apparent saturation dramatically.
Daylight (5500K–6500K). The truest color reading. Stones evaluated in daylight match GIA grading conditions.
Incandescent (2700K, warm yellow). Adds warmth to everything. Near-colorless stones can look more colorless under incandescent. Cool-toned colored stones (Peacock, Twilight, sapphire) show less saturation; warm-toned stones (Champagne, ruby) show more.
LED (3000K–5000K, varies). Modern LEDs come in multiple color temperatures. "Warm white" (3000K) behaves like incandescent. "Daylight" (5000K) behaves like sunlight. Most homes use warm white; most retail uses daylight to show stones at peak.
Candlelight (1900K, very warm). Heavy yellow cast. Antique cuts (Old European, Old Mine) were optimized for candlelight, which is why antique stones can look more beautiful in restaurants than modern brilliants.
Practical implication for colored stones: Always evaluate a colored stone in multiple lighting conditions before committing. A stone that looks magical in showroom daylight may read flatter in your home's warm lighting — or vice versa, a stone that looks subtle in showroom may come alive at home. Our 360° videos show stones in multiple lightings; ask our team for what you need.
Section 10: Trade-offs
Color tier vs. carat weight (lab diamond). For the same budget, dropping from F to H frees up budget for 0.2–0.4 more carats. Most buyers feel a larger stone reads as "more" than a slightly more colorless smaller stone — but this is personal.
Color vs. clarity (lab diamond). For most buyers in the F–I color range with VS1–VS2 clarity, the result looks identical to a D–IF stone in a finished ring. Pushing both grades to maximum simultaneously rarely delivers visible value.
Boutique vs. Group lab diamond. Boutique gives you our cutting craft and curated quality. Group gives you maximum selection and price match. Many buyers start with Boutique for the engagement ring and use Group for wedding bands, side stones, or larger anniversary upgrades.
Moissanite vs. lab diamond, clear. At smaller sizes (under 1.5ct), moissanite and lab diamond clear stones look similar to most viewers. At larger sizes (2.5ct+), differences become more visible — moissanite shows more rainbow fire; lab diamond shows more "depth" and less rainbow fragmentation. Buyers who notice and prefer one over the other usually know within 30 seconds of comparing in person.
Moissanite vs. lab diamond, colored. Colored moissanite generally reads as more dramatic and saturated. Colored lab diamond reads as more refined and traditional-fancy-color. Both beautiful; different identities.
Colored gem vs. colored moissanite. Colored gems carry traditional gem identity (sapphire, ruby, emerald are immediately readable as those things). Colored moissanite carries modern, fire-driven identity. Birthstone considerations often push toward colored gems.
Specialty colors vs. standard. A specialty-colored stone will never look like a colorless stone; that's the point. Don't try to "compromise" between specialty color and colorless — pick one direction and commit.
Section 11: From our community
The following reflects patterns and themes we've heard repeatedly across our 50,000+ member community and post-purchase reviews. Composites and paraphrased patterns, not direct quotes.
On choosing between moissanite and lab diamond, clear: Customers are split. Some find clear lab diamond has more "depth" or transparent quality than moissanite, especially in fancy shapes (pear, oval, radiant, princess). Others find that well-cut moissanite at the same size and quality has more visible sparkle and life. A repeated insight from owners of both: the difference is most noticeable in fancy shapes, less noticeable in round. In emerald cut especially, several customers report they cannot tell the difference between their lab diamond and their moissanite.
On rainbow fire as the deciding factor: Many community members describe rainbow fire as the single biggest visual difference. Some prefer the calmer, more monochromatic light return of lab diamond; others love moissanite's rainbow flashes and find lab diamond comparatively muted. There's no objectively "better" — it's preference.
On wearing both: A common pattern: customers who own both a moissanite ring and a lab diamond ring tend to wear them on different hands, rotating the role of "primary" engagement ring over time. We've seen long-time customers describe wearing a Peacock Blue moissanite on one hand and a Boutique blue lab diamond on the other for weeks at a time.
On colored moissanite preferences:
- Smokey Sparks Grey has a fiercely loyal community. Repeat customers describe themselves as "Smokey Sparks girls" — once they own one, they keep coming back. The chameleon effect in different lighting is the most-cited reason. Frequent ask: bring it back in larger sizes.
- Peacock Blue converts curious shoppers into committed buyers faster than most colors. Common pattern: "I had no idea moissanite could look like this." The iridescence is immediately legible. Several community members have switched from a planned Smokey Sparks purchase to Peacock Blue after seeing a real stone.
- Twilight Blue polarizes — buyers either fall in love immediately on seeing a stone, or never seriously consider it. 360° video doesn't fully capture the depth of the blue; in-person viewing converts hesitators.
- Stardust Grey has the most quietly loyal customer base. Stardust Grey buyers tend to come from creative professions, often own no other diamond jewelry, and frequently choose minimalist solitaire settings or rose-cut combinations.
- Champagne is often chosen by buyers reproducing or honoring a vintage family piece, or who wanted yellow diamond but were pushed out by pricing. The community especially loves Champagne in Nova cut for its rainbow flashes against the warm body.
- Accident Colors generate cult excitement. When a batch drops, our community is on it within hours. Dark green ("black green") and pale yellow are particularly missed when not currently available — community members regularly ask when they'll return.
On Boutique colored lab diamond: Customer interest in pink lab diamond has accelerated as Boutique pricing has come down. The repeated pattern is: "I always wanted a pink diamond; now I can finally have one." Vivid blue and vivid green attract buyers drawn to fancy color generally, often with no specific prior color preference.
On colored gemstones: Buyers of our lab sapphire, ruby, and emerald often come in considering moissanite first, then move to colored gem because they want classical gem identity rather than colored moissanite's modern character. The decision usually crystallizes after seeing both in person — sapphire and ruby in particular have a "weight" of identity that colored moissanite doesn't try to replicate.
On lighting and saturation: Repeated feedback for colored stones: customers who evaluate only in showroom or daylight sometimes discover their stone reads differently in home lighting. We always recommend evaluating in both bright and warm lighting before committing — especially for blue and grey moissanite, which can shift dramatically.
Patterns across all materials: The buyers most satisfied 5+ years later are not the ones who optimized any single dimension — they're the ones who chose the stone they loved on first sight, in the lighting they'd wear it in. Specifications matter; aesthetic intuition matters more.
Section 12: Common mistakes to avoid
Mistake 1: Maximizing color and clarity simultaneously. D–IF lab diamond is the most expensive combination available, and visually identical to F–VS2 in a finished ring. Redirect that budget to size or to fancy cut.
Mistake 2: Ignoring setting metal in color decisions. The single most common preventable mistake: buying a J–K lab diamond intending to set it in white gold. The result reads warmer than expected. Choose color and setting metal together.
Mistake 3: Trusting online photos for specialty colors and colored gems. Color photographs unreliably online. Stardust Grey photographs flatter than it looks; Twilight Blue photographs either too vivid or too pale; sapphire saturation depends entirely on the photographer's white balance. Always evaluate via 360° video or in person for colored stones.
Mistake 4: Assuming Boutique = expensive, Group = cheap. They serve different needs. Boutique can be very accessible at smaller sizes; Group includes both budget-tier and ultra-premium stones. Don't pre-judge a line based on its name.
Mistake 5: Confusing colored moissanite with colored lab diamond. They're different materials with different optical character. A Peacock Blue moissanite and a Boutique vivid blue lab diamond share the color "blue" but otherwise feel very different on the hand. Compare both before committing.
Mistake 6: Body chemistry mismatch. Skin tone affects how a stone's color reads on the hand. Cool skin tones tend to harmonize with white metals and colorless stones. Warm skin tones often look better with yellow gold and slightly warmer stones. Olive skin can carry both.
Mistake 7: Not asking about price match. If you've found a Lab Diamond Group stone listed cheaper at another vendor, our price match guarantee covers it. Many customers don't ask, then discover after purchase that we would have matched. Always ask.
Mistake 8: Not asking about Smokey Sparks availability before falling in love. Smokey Sparks Grey has limited inventory and may not be available in your target size and shape. Confirm availability with inquiry@doveggs-seattle.com before committing your heart to a Smokey Sparks plan.
Section 13: Glossary
Color grade — A letter grade (D–Z) for diamonds. D is most colorless; Z has visible color.
Colorless tier (D, E, F) — No visible color in finished jewelry under any normal viewing condition.
Near-colorless tier (G, H, I, J) — Faint warmth detectable only under controlled comparison; not visible face-up to most viewers.
Faint tier (K, L, M) — Visible warmth in some lighting, especially against white metals.
DEF tier (DovEggs moissanite) — Our top clear moissanite tier. Inventory is hand-picked to D color despite the broader DEF label.
GHI tier (DovEggs moissanite) — Our value clear moissanite tier. Inventory is hand-picked to E–F color despite the broader GHI label.
Boutique (DovEggs lab diamond) — Our in-house grown and cut lab diamond product line. Focus on fancy cuts, curated colors, limited pieces.
Essential (DovEggs lab diamond) — Our in-house grown and cut lab diamond in standard cuts. Same growth and cutting standards as Boutique, different cut focus.
Lab Diamond Group — Our partner-lab inventory access, 10,000+ certified stones, every color and cut, price-matched.
Specialty color (or "fancy color") — Stones intentionally colored outside the white range. Includes Peacock Blue, Twilight Blue, Stardust Grey, Champagne moissanite, plus pink/green/blue Boutique lab diamond, plus colored gems (sapphire, ruby, emerald).
Accident Color — One-of-a-kind moissanite color produced as an unstable byproduct of growing other proprietary colors. Cut into limited drops.
AAAAA (sapphire) — The top sapphire color category — deep, intense, even royal blue without grey or green undertones.
Pigeon blood (ruby) — The rarest red category in ruby — deep, slightly fluorescent, warm without orange shift. Also called Burma red.
Zambia green (emerald) — Deep green with slight bluish overtone, the classic "emerald green" most people picture.
Refractive index — How much a stone bends light. Higher = more brilliance. Diamond is 2.42; moissanite is 2.65 (higher).
Dispersion — How much a stone splits white light into rainbow colors (the "fire" effect). Diamond is 0.044; moissanite is 0.104 (more than 2× as dispersive).
Price match — Our commitment that any Lab Diamond Group stone listed cheaper at a reputable vendor will be matched at DovEggs.
Semi-mount — A finished setting waiting for its center stone. All DovEggs semi-mounts work with all DovEggs stones (moissanite, Boutique, Essential, Group, colored gems).
Section 14: Frequently asked questions
What's the difference between DovEggs Boutique and Lab Diamond Group?
Boutique is our in-house grown and cut lab diamond, focused on fancy cuts (Modified Ashoka, OEC, OMC, Rose, Crown Arrow™, Modified Sakura) and a curated set of value-retaining colors (currently pale pink, vivid green, vivid blue). Limited pieces. Group is our partner-lab inventory access — 10,000+ certified stones in every color, shape, and cut available on the market, priced individually and price-matched.
Can I use a Lab Diamond Group stone with a DovEggs setting?
Yes. Every DovEggs setting (semi-mount) works with every DovEggs stone — Boutique, Essential, Group, moissanite, or colored gems. Many customers buy Group stones specifically because they get our setting quality, lifetime warranty, and customer service while also accessing the broader stone market.
Do you price match Lab Diamond Group stones?
Yes. If you find the same Group stone listed cheaper at another reputable vendor, we'll match the price. Email inquiry@doveggs-seattle.com with the competing listing's URL and certification details.
Should I get D color or F color for a lab diamond?
Visually, D and F look identical face-up in a finished ring. The price difference is 8–15%. We recommend F for buyers who want top-tier colorless without the D premium. Buyers who specifically want the D certificate (for resale, insurance, or peace of mind) should choose D.
Is moissanite color the same as diamond color?
The grading scale is the same (D–Z), but how we apply it differs. DovEggs hand-picks every clear moissanite stone, and our tier labels are conservative: stones sold as "DEF" are actually D, and stones sold as "GHI" are actually E–F. Most customers find what we call GHI looks colorless in finished rings, despite the near-colorless label.
What color grade should I get for a yellow gold lab diamond setting?
You have flexibility. G, H, or I will look colorless in yellow gold to nearly all viewers. J–K can also work beautifully and saves significantly. We typically recommend G–H for buyers who want to feel safe, and J for buyers prioritizing value.
Are specialty colors (Peacock Blue, Twilight Blue, etc.) graded?
Specialty colors are not graded against the D–Z scale because they are deliberately colored outside that range. They have internal DovEggs consistency standards — we evaluate hue, saturation, and tone, and reject stones that don't meet those standards. Twilight Blue, Stardust Grey, and Smokey Sparks Grey are particularly demanding because each is a DovEggs-developed color with narrow acceptance windows.
Do you coat your colored moissanite?
No. Every colored moissanite stone we sell is grown to its color from raw material. The color is intrinsic to the stone, present at every depth, and stable indefinitely. Coated stones (sold by some vendors) develop color from a thin surface layer that wears off over years. Ours don't.
Can DovEggs cut a custom color + cut combination?
Yes — and this is one of the most distinctive parts of buying from us. For non-standard combinations (e.g., a 3ct Nova-cut Twilight Blue, or a Pixel-cut Peacock Blue, or a Modified Sakura ruby), we cut multiple stones to your specifications and let you choose from the lot. Each piece has subtle individual differences. Lead time is typically 4–8 weeks. Email inquiry@doveggs-seattle.com to start the inquiry.
Why is Smokey Sparks Grey treated differently from your other colors?
Smokey Sparks Grey has limited raw stone supply, so it's only available in certain sizes and shapes. We can't always produce it on demand. Always email inquiry@doveggs-seattle.com before ordering Smokey Sparks to confirm availability for your target spec — otherwise you may fall in love with the idea and find we can't fulfill it in your size.
Are your colored gemstones (sapphire, ruby, emerald) lab grown?
Yes. DovEggs is a 100% lab-grown brand for environmental reasons. All our sapphires, rubies, and emeralds are lab-grown using cosolvent technology. They have the same chemical composition and physical properties as natural gems — only mass spectrometers can distinguish them.
Can your colored gemstones be cut in your specialty cuts?
Yes — every colored gem in our catalog can be cut in any cut we offer, including Crown Arrow™, Pixel™, Sakura, Astro, Nova, Empress, Modified Ashoka, Modified Sakura, OEC, OMC, Rose, and Portuguese, in addition to all standard cuts. This is unique to DovEggs; most colored-gem vendors offer a small subset of standard cuts only.
What's the most popular color choice at DovEggs?
For lab diamonds: F and G are the top two clear grades, roughly equal in volume. For clear moissanite: GHI tier (which is actually E–F color) is the most-chosen, followed by DEF tier. For colored moissanite: Peacock Blue is our most popular, followed by Champagne, Twilight Blue, and Stardust Grey. For Boutique colored lab diamond: pale pink leads, with vivid green and vivid blue close behind.
Will my stone change color over time?
No. Lab diamond color is stable indefinitely. DovEggs colored moissanite is stable because we grow rather than coat. Our colored gemstones (sapphire, ruby, emerald) are also stable — they're chemically identical to natural gems and behave identically over time.
What about fluorescence in lab diamonds?
Fluorescence can be neutral, helpful, or harmful depending on the stone. Faint or medium fluorescence in a near-colorless stone can make it appear whiter in daylight (a benefit). Strong fluorescence in a colorless stone can occasionally cause a hazy appearance. We disclose fluorescence on every lab diamond and our team will guide you when it matters.
Does color affect resale value?
For lab diamonds: D, E, F retain value best. Boutique colored lab diamonds (pink especially) have stronger fancy-color secondary markets than mined fancy color held proportionally. For colored moissanite and colored gems: resale is mostly through DovEggs (we accept buybacks at fair market rates); broader secondary markets are still developing for these specialty categories.
