Moissanite is a near-colorless gemstone that’s composed of silicon carbide. First discovered by Henri Moissan, a French scientist, moissanite was originally found in the crater left behind by a fallen meteor. In addition to the diamond’s signature brilliance, the gemstones also emit fire, which is the reflection of color, or rainbow light. Moissanite also gives off a vibrant colored light reflection. In some cases and under certain light, the moissanite emits extensive color dazzling, which makes it highly desirable to collectors.
