Until recently all moissanite possessed a small amount of greyish or greenish (green is particularly characteristic) occlusions, what puts them in the range of F or lower comparing with diamonds (D is considered as the best possibility on the market). It is important to know such diamonds are meant just for white gold, platinum or similar settings because yellow one would neglect the colorlessness of the stone.
For this reason, numerous buyers don’t really care about the grade of color, because they plan to put the stone in yellow, rose or similarly colored setting anyway. Diamond graded between G and J is considered as a best-buy option for such buyers and having lots of moissanite with way better grades this problem is relatively unimportant.
On the other way, the market for colored stones is growing. If somebody wants blue, green, yellow or pink stone, moissanite offers at least as much as colored diamonds. In this case, gradation is completely different than the one presented above.
There is another important fact to consider. Technology for making moissanite is improving year after year and several enhancements were made – leading to Neo, Supernova, Forever Brilliant, Forever One and the ultimate compound of silicon and carbon grown in star-like conditions: Amora Gem. Amora Gems surpass diamonds even in their traditionally untouchable category – hardness, but are in such demand, you have to enter a waiting list if you want to buy one.
