Buying loose moissanite online comes down to three things: a seller who is clear about what you are getting, a stone whose cut and color you have actually seen, and a setting plan for later. DovEggs has been making moissanite jewelry since 2014, and every loose stone is made to order and hand-picked. Below is what to check before you buy, plus where moissanite is not the right choice.

Why buy the stone loose?

Buying loose lets you choose the exact stone first, then decide on the setting. You can compare shapes and colors side by side without a ring in the way, and you can take your time with the design. It also means you can order the stone and the setting together or as two separate orders, whichever suits you.

What to check in a reputable seller

• Clear stone descriptions. The listing should tell you the shape, the millimeter size, the color grade and the cut style, not just a carat number.
• Real photos and videos. Ask for a video of the actual stone when it is in hand. A good seller will show you the stone rather than a stock image.
• Honest certificate talk. Moissanite is certified, but no certificate is shipped with the order at DovEggs. That is normal for moissanite; the value is in the stone and the warranty, not a paper card.
• A written warranty. Look for a lifetime warranty on the stone itself, covering brilliance, fire and physical integrity.
• A return window. DovEggs offers 30-day returns on all jewelry, counted from the day you receive it.
• Clear metal options. Sterling silver, solid 10k/14k/18k gold and solid platinum should all be listed plainly.

Cuts: the part that matters most

Cut is what makes moissanite sparkle. A well-cut stone returns light; a poorly cut one looks flat no matter how white it is. Standard brilliant cuts are the safe, classic choice. Beyond that, DovEggs offers a range of signature and specialty cuts, including Hearts & Arrows, Nova, Astro, Empress, Unity, Criss, Sakura, rose cut and crushed-ice styles, plus antique cuts OMC (Old Mine Cut, cushion) and OEC (Old European Cut, round).

One honest note: the elongated cushion cut has a fixed ratio, so it cannot be cut slimmer or longer on request. If you want a longer, narrower look, an elongated oval, the Empress cut, or a lab diamond modified elongated cushion are the alternatives.

Sizes: carat is not the whole story

Moissanite is measured by millimeter dimensions, and the same carat weight can look different depending on the shape. DovEggs uses a stone size chart as the master reference, so when you give a carat weight the team confirms the actual mm size with you. For example, a 1.5ct Empress is 6×7mm, an oval is 6×8mm, and a round is 7.5mm. Checking the mm size is the single best way to avoid surprises.

Color grades and colors

DovEggs labels its colorless moissanite conservatively. The DEF tier is actually D color, and the GHI tier is actually E–F color, because every stone is hand-picked. Both are white stones; DEF is the whiter of the two.

Colored moissanite comes in two very different groups:

• Regular colors — Twilight Blue, Stardust Grey, Peacock Blue, Champagne and Black. These are made to order like any other stone, so you can choose your shape and size.
• Accident Colors — limited one-off stones that exist only in the Exclusive Color collection, such as Lemon Drop yellow, Fancy Yellow, Aurora Teal, Midnight Evergreen, Deep Forest Teal, Hawaii Blue and Olive Green. Each exists only in the shape, cut and carat size listed, and cannot be reproduced.

Stardust Grey varies from stone to stone, and smaller sizes are generally cut in lighter shades. If you want a specific depth of grey, ask the team to check inventory and send videos of two shades side by side. The smallest colored moissanite DovEggs can custom make is 0.5ct / 5mm; below that, colored gemstone accents or clear white accents are the options.

What a moissanite certificate really means

Moissanite is certified, but no certificate is included with the order. This is worth understanding before you buy: the certificate is not what protects you. What protects you is the lifetime warranty, which covers the stone's optical properties (brilliance and fire) and physical integrity, including clouding or defects. If a stone is defective, it is replaced at no cost after inspection. The warranty does not cover accidents, abuse, loss or normal wear and tear.

Setting it later

You can order a loose stone now and a setting later, or both together. DovEggs can set your own moissanite or colored gemstone into a DovEggs setting. One limit to know: DovEggs does not set customer-provided lab-grown or natural diamonds, and does not offer semi-mounts for non-DovEggs lab diamonds. If you are planning a lab diamond center stone, choose it from DovEggs so the setting and stone are matched.

Moissanite vs lab diamond: where the other stone wins

Moissanite is a beautiful, durable stone with more rainbow fire than diamond, and it costs less. But it is not the right choice for everyone. If you want a stone that is chemically identical to a mined diamond, reads as diamond to a jeweler's eye, or comes with an independent grading report, a lab diamond is the better choice. Lab diamonds are also the better pick if you want a very specific cut that moissanite does not offer, or if you simply prefer a diamond's whiter, more subtle sparkle over moissanite's fire.

	Moissanite	Lab diamond
Look	More rainbow fire, very bright	Whiter, more subtle sparkle
Grading report	Certified, but no certificate shipped	IGI or NGIC depending on the line
Color range	DEF, GHI, plus regular and limited colors	Standard DEF, plus fancy colors
Best for	Maximum sparkle and value	Diamond look and independent grading

FAQ

Can I see a video of a specific loose stone before I order?

If a specific stone is not in hand, DovEggs cannot send an actual video before you order. The real video is sent after the stone arrives, and you may cancel for a full refund.

Does my loose moissanite come with a certificate?

Moissanite is certified, but no certificate is included with the order. Your protection is the lifetime warranty, which covers the stone's brilliance, fire and physical integrity.

Can I buy the stone now and the setting later?

Yes. You can order the stone and setting as one order or as two separate orders, so you can choose the stone first and design the ring afterward.

Can DovEggs set a stone I already own?

Yes, DovEggs can set your own moissanite or colored gemstone into a DovEggs setting. DovEggs does not set customer-provided lab-grown or natural diamonds.

What is the smallest colored moissanite you can make?

The smallest colored moissanite DovEggs can custom make is 0.5ct / 5mm. If a design's accent stones are smaller than 5mm, colored gemstone accents or clear white accents are used instead.

How do I know which size to choose?

Give the team the carat weight you have in mind and they will confirm the millimeter dimensions using the stone size chart, so the shape and color you pick match the real size.
