GRA Cert Moissanite Gems

It is an extremely durable gemstone. Moissanite has more sparkle and brilliance than a diamond, making it a desirable choice for those who want to make a statement. Moissanite gemstones are a 9.25 on the Mohs Scale of Hardness comparable to 10 of a diamond, which is perfect because these gemstones will be inside the watch case. Moissanite gemstones have a refractive index from 2.65 – 2.69, which is higher than a natural diamond, which means that it will sparkle brighter when light catches it. Because Moissanite are lab created, they are an eco-conscious gemstone as they require no mining.
