Cubic zirconia is the cubic crystalline form of zirconium dioxide—a synthetic, colorless gemstone. Unlike diamonds, which are naturally occurring gemstones, cubic zirconia is lab-created and made by melting zirconium oxide powder with stabilizers like magnesium and calcium. Cubic zirconia allows you to choose high-quality and low-cost materials that have the capabilities of mimicking the appearance of real diamond jewelry at a fraction of a cost. http://www.jiangyuanjewelry.com/
