What is Moissanite? | Ritani
Moissanite is a diamond simulant made of silicon carbide. A diamond simulant is a stone that has a similar appearance to a diamond, but is not a real diamond. It is very difficult to tell apart a diamond & moissanite, making moissanite a common diamond alternative. Pinterest Moissanite was originally discovered in a meteor crater in 1893 by scientist Henri Moissan. He mistakenly believed the
