How are lab grown diamonds made?
Most lab grown diamonds are grown by a technique called chemical vapor deposition (CVD) or high pressure high temperature (HPHT) crystal formation. They are diamonds produced in high-tech instruments that simulate the natural environment, and the growth process takes about 3 months.For many lab grown diamonds, they are created by the best scientists, the most professional engineers and skilled technicians, and are the crystallization of human science and technology wisdom. In addition to traditional colorless diamonds, lab grown diamonds can also have more and richer colors.Pink, yellow and blue diamonds can all be made manually in the laboratory.Consumers associate the term artificial with artificial products and believe that it is not a diamond that occurs naturally on the earth, but is cultivated in a laboratory, so it is generally misunderstood that lab grown diamonds are not real diamonds.But their chemical composition and physical characteristics are the same as those of mined diamonds, and they are as dazzling as natural diamonds, which proves that it is a real diamond --- transparent crystal of pure carbon element.
How is Moissanite made?
It was first discovered on meteorites.The natural environment of the earth can not form natural moissanite at all.Therefore, only natural meteorite is brought from outer space.This may be more than many diamonds. It is also rare. Therefore, 100% of the moissanite that can be purchased on the market is artificially synthesized.In the 1990s, through the combination of science and art, scientists were able to thermally grow silicon carbide crystals to make this amazing gem. So we can know that its main component is silicon carbide.
The difference between lab-grown diamonds and diamonds
The main difference between lab grown diamonds and naturally mined diamonds is their source-the diamonds formed and how long it takes to make them. One was created in the laboratory and the other was created in the earth.So that's why they have a big difference in price. A 1-carat CVD lab grown diamond can be bought for about a half of the price of a natural diamond, and it is also a high-grade gem-quality lab grown diamond with a color clarity of the highest level.
The difference between Moissanite and diamond
Diamonds come in blue, pink, yellow and white. Moissanite is a white (or actually transparent / transparent) colorless gem. Unlike diamonds, moissanite can be made completely colorless-something that is almost impossible to buy at an affordable price in the diamond world. If you compare moissanite with diamonds of the same size and color, the average diamond cost is four to six times or more.What about sparks or glory? There is a measurement method called "refractive index". In the refractive index (RI), moissanite is 2.65-2.69, while diamond is 2.42. In other words, moissanite is more shiny than diamond.
All in all, moissanite is almost as hard as diamonds, so they can live like diamonds forever. They have the same color and clarity, but unlike diamonds, they can be made colorless. What's more, moissanite has no impact on the environment and they cost only a fraction of the cost of diamonds.
