Cubic zirconia is manufactured of zirconia (zirconium oxide, ZrO2) powder mixed with stabilizers and some pieces of zirconium metal. This mixture is melted at 2750 C and then allowed to cool and crystallize. Cubic zirconia's properties differ substantially from those of diamond. For this reason, CZ is properly called a diamond imitation, not a synthetic diamond.
CZ 則是用鋯的細晶體，二氧化鋯粉末及安定劑混合後，在攝氏二千七百五十度的高溫下將其溶解，待冷卻結晶後再磨製成的產品，其亮度成色雖與天然鑽石類似，實際上卻是不同。
