Moissanites are not the same as lab grown diamonds. Lab grown diamonds are real diamonds that share the same chemical, physical, and optical properties as earth-mined diamonds. Meanwhile, Brilyo Moissanites are not diamonds -- but are the closest you can get to a diamond for a fraction of the price. Our moissanites are specially crafted to reduce the fire or rainbow sparkle as much as possible so that it closely resembles a diamond. Learn more about our gemstone options here.
