Moissanite (/ ˈ m ɔɪ s ə ˌ n aɪ t /) [5] is naturally occurring silicon carbide and its various crystalline polymorphs. It has the chemical formula SiC and is a rare mineral , discovered by the French chemist Henri Moissan in 1893.
Peridot (/ ˈ p ɛ r ɪ ˌ d ɒ t,-ˌ d oʊ / PERR-ih-dot, -doh), sometimes called chrysolite, is a yellow-green transparent variety of olivine.Peridot is one of the few gemstones that occur in only one color.
As a gemstone used in jewelry, silicon carbide is called "synthetic moissanite" or just "moissanite" after the mineral name. Moissanite is similar to diamond in several important respects: it is transparent and hard (9–9.5 on the Mohs scale, compared to 10 for diamond), with a refractive index between 2.65 and 2.69 (compared to 2.42 for diamond).
Moissanite actually has a higher refractive index than diamond, and when presented beside an equivalently sized and cut diamond will show more "fire". Cultured, synthetic, or "lab-created" gemstones are not imitations: The bulk mineral and trace coloring elements are the same in both.

Cubic zirconia (abbreviated CZ) is the cubic crystalline form of zirconium dioxide (ZrO 2).The synthesized material is hard and usually colorless, but may be made in a variety of different colors.
