MOISSANITE
These beautiful stones are near-colorless gemstone that’s composed of silicon carbide- an extremely rare, naturally-occurring mineral. It has a similar appearance as a real diamond and the only gemstone that passes as a diamond on a standard handheld diamond point tester. Our moissanites are more heat resistant than even diamonds, meaning that even if they were in a fire, they would still retain their sparkle and form. They have a Refractive Index (RI) of 2.65 whereas diamond’s RI is lower at 2.42. Moissanite has an extremely high level of brilliance and excellent light performance. This is one reason it is a favorite stone in engagement rings as it has much higher brilliance and fire than a diamond. The hardness of diamond is about 10 and moissanite is about 9.25. Our moissanite has its unique waist code, and it is certified by the international famous professional appraisal organization and the global gemstone Research Association (GRA).
