Cubic Zirconia Stone, 4mm Round, AAA - Emerald (Each)

Cubic zirconias are synthetic (manmade) gemstones. Like diamonds and natural zircons, cubic zirconias have a very high refractive index, which translates to high amounts of sparkle.
CZs are extremely durable and can withstand high temperatures. Most colors can be fired in kilns with metal clay, a process that ruins most other gemstones. The gemological properties of CZs vary by manufacturer due to variances in the type and amount of stablizer used to make isometric (cubic) crystals. After controlled annealing to ensure the flawless crystals are stable, CZs are cut into faceted gemstones. You can safely clean your cubic zirconias with any jewelry cleaner or detergent. Be sure to rinse well to avoid leaving a residue that would dull the gem's shine.
