Based on consumer demand on certain online channels, Charles & Colvard introduced a limited assortment of moissanite jewelry with lab created colored stones. These lab grown colored gemstones include lab grown blue and pink sapphires, as well as lab grown rubies. Just like moissanite, these colored gemstones are identical to those that are mined from the earth, chemically, optically and physically. The only differences are in cost and environmental impact.
