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. Gemstone irradiation - Wikipedia

   en.wikipedia.org/wiki/Gemstone_irradiation

   Gemstone irradiation is a process in which a gemstone is exposed to artificial radiation in order to enhance its optical properties.High levels of ionizing radiation can change the atomic structure of the gemstone's crystal lattice, which in turn alters the optical properties within it. [1]

5. 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).

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 ...
