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.
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.
A quick-start guide or quickstart guide (QSG), also known as a quick reference guide (QRG), is in essence a shortened version of a manual, meant to make a buyer familiar with their product as soon as possible. This implies the use of a concise step-based approach that allows the buyer to use a product without any delay, if necessary including ...
The toughness of natural diamond has been measured as 50–65 MPa·m 1/2. [contradictory] [34] [35] This value is good compared to other ceramic materials, but poor compared to most engineering materials such as engineering alloys, which typically exhibit toughness over 80 MPa·m 1/2. As with any material, the macroscopic geometry of a diamond ...
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 ...
