Question: What Is the Difference Between Cubic Zirconia and Cubic Zirconium?
Cubic zirconia and cubic zirconium are not the same thing. Take a look at the difference between cubic zirconia and cubic zirconium.
Answer: CZ is the abbreviated name given to the world's most popular diamond simulant, cubic zirconia. Cubic zirconia is manmade crystalline zirconium dioxide, ZnO2. Sometimes people mistakenly refer to CZ as cubic zirconium or they believe cubic zirconium is another name for the gemstone zircon. Zircon, crystalline zirconium silicate (ZrSiO4), exhibits tetragonal crystalline structure instead of cubic crystalline structure. There is no cubic zirconium.
