   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).

5. 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).

6. Extraterrestrial diamonds - Wikipedia

   en.wikipedia.org/wiki/Extraterrestrial_diamonds

   On Earth, the natural form of silicon carbide is a rare mineral, moissanite. [19] In the Solar System the rocky planets Mercury, Venus, Earth and Mars are 70% to 90% silicates by mass. By contrast, stars with a high ratio of carbon to oxygen may be orbited by planets that are mostly carbides, with the most common material being silicon carbide ...
