Cubic zirconia (CZ) is a derivative of zirconia (ZrO2) which converts from the sintering monocrystalline phase to the polycrystalline cubic form. In jewelery, zircon tablets are replaced by cubic zirconia as a terminology mistake. However, zirconium oxide (ZrO2) is a derivative of zirconium oxide. The main zirconium is the zirconium mineral whose chemical composition is ZrSiO4.
