2. Moissanite - Wikipedia

   en.wikipedia.org/wiki/Moissanite

   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.

3. Diamond simulant - Wikipedia

   en.wikipedia.org/wiki/Diamond_simulant

   Moissanite is superior to cubic zirconia in two ways: its hardness (8.5–9.25) and low SG (3.2). The former property results in facets that are sometimes as crisp as a diamond's, while the latter property makes simulated moissanite somewhat harder to spot when unset (although still disparate enough to detect).

4. Silicon carbide - Wikipedia

   en.wikipedia.org/wiki/Silicon_carbide

   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).

   [48] [49] At high pressure (~20 GPa (2,900,000 psi)) diamond can be heated up to 2,500 °C (4,530 °F), [50] and a report published in 2009 suggests that diamond can withstand temperatures of 3,000 °C (5,430 °F) and above. [51] Diamonds are carbon crystals that form under high temperatures and extreme pressures such as deep within the Earth.
