Item: Emerald Cut Cubic Zirconia Gemstones
Cubic zirconia (CZ) is the cubic crystalline form of zirconium dioxide (ZrO2). The synthesized material is hard, optically flawless and usually colorless, but may be made in a variety of different colors. Cubic Zirconia, as a diamond substituent and gem competitor, has been seen as a potential solution against conflict diamonds and the controversy surrounding the rarity and value of diamonds. The CZ sold by MultiGems are 'colorless' and flaw-free.
