Synthetic Diamonds


Synthetic diamonds

For people who can not afford real diamonds or want a 100 percent guarantee that their diamonds are conflict-free, synthetic diamonds are a good substitute. For many years, which is the only option was synthetic cubic zirconia, but now consumers can also choose from Moissanite and manmade diamonds.

Cubic zirconia, commonly known as CZ, is a gem laboratory that has been on the market since 1976. It is a hard bead (8.5 on the Mohs scale), but it is not as hard as diamond. On the one hand, CZ compositionally superior diamond. CZ has more shine and sparkle, it is absolutely colorless, and it has no recordings. But most consumers agree that CZ is simply too perfect - it looks artificial, even with the naked eye. Because of this, some CZ manufacturers began to produce the pearl with colored shades and inclusions, so it more closely resembles the diamond.

Moissanite has been CZ largest synthetic rival. Moissanite became available in 1998, and it is even more similar to diamond in composition and appearance. Moissanite is harder than CZ, but at 9.5 on the Mohs scale, it is still softer than diamond. Moissanite's color is pale yellow or green and tint becomes more visible in larger stones. It also has small, stretch-mark-like inclusions, which form during his growing process. Like CZ, Moissanite is more brilliant than diamond, but this quality is considered as a drawback rather than an advantage.

The closest approximation to the synthetic diamond is a man-made diamond. In contrast to the CZ and Moissanite, synthetic diamonds are pure carbon. The Gemological Institute of America (GIA) recognizes these as genuine diamonds from a composition perspective. But, the man-made diamonds are not the rich geological history that natural diamonds do. Laboratory simulation of the heat and pressure from the Earth's mantle, which creates natural diamonds. For the synthetic producers and consumers, diamonds come down to a matter of time and money: day to millions of years, thousands of dollars compared to tens of thousands of dollars or more (synthetic diamonds sell for about 30 percent less than natural to them) [source : MSN]. If you want a unique color, relatively cheap diamond (it will cost less than a natural colored diamond) you can find man-made them in the colors orange, yellow, pink and blue. Find a big diamond will be a bigger challenge - the majority of synthetic diamonds weighing less than a carat. If you want the best man has to offer, synthetic diamonds are a no-brain. While jewelers can have trouble telling them apart from natural. To prevent retailers from passing without synthetic diamonds as natural to them, the GIA is selling machines that will help jewelers easily distinguish between the two.

It may come as no surprise that the developer behind these machines is none other than King of the natural diamond industry
