Synthetic Moissanite 8.679ct loose stone
Moissanite (Moissanite) has a hardness of 9.5, second only to diamond, which has a hardness of 10, and a higher dispersion rate than diamond, sphene, and demantoid garnet. In fact, it is quite a suitable mineral for jewelry. It is extremely rare to find it in nature, so the ones that are commonly available are synthetic gemstones. This is also synthetic moissanite. Moissanite comes in a variety of colors, so it is fun to collect them. Please enjoy this dazzling brilliance in your hands. This loose stone was cut by a skilled craftsman from Sri Lanka, Mr. Sanjay. Moissanite has a high hardness of 9.5, so it is only possible to polish about two stones per day to create a custom cut with a large number of special facets.
