Moissanite and Diamond - How To Tell The Difference
Natural moissanite is a very rare mineral composed of silicon carbide. Because of its rarity, nearly all of the moissanite available today was created in a lab. With a 9.25 score on the Mohs Scale of Hardness, it is not as hard as a diamond (with a score of 10) but is very durable and strong enough for everyday use.

Carbide Types in Knife Steels - Knife Steel Nerds
2019/7/15· Silicon carbide has a similar hardness to those hard carbides but is not clearly harder, and in general silicon carbide is not as good at cutting steel as aluminum oxide. CBN and diamond are significantly harder than any of the carbides so they are generally better at least in terms of grinding and polishing high wear resistance steels with hard carbides.
