Moissanite (Moissanite)

Moissanite has a similar appearance to a diamond and emits strong fire. Although it exists in the natural world, it is extremely rare, so the most commonly distributed stones are synthetic stones made artificially. In addition to colorless, there are many other shades such as blue, green, red, gray, and brown.
