Moissanite gemstone is not a diamond all the Moissanite gemstones are Lab-Grown gems that look and feel like a diamond without imperfections. Natural diamonds without imperfections are rare and very expensive but an excellent quality Moissanite like the Forever One from Charles Colvard cost just the fraction of a natural diamond that only a trained gemologist can tell the difference.
