Cubic Zirconia is a synthetic diamond made of zirconia commonly called cubic and abbreviated as CZ.
CZ is stabilized with calcium oxide and maintain the isometric system.
If you add cerium, chrome, nickel to zirconium oxide, it turns to orange and red, green and brown color of cubic zirconia each. In high temperature. It has cubic crystal structure in high temperature and when it cools it turns to tetragonal, orthorhombic, monoclinic crystalline structure, etc.
To replace diamond, it should maintain the cubic structure, so it stabilized with calcium oxide or yttrium oxide etc. At this moment, Mohs hardness depends on the composition of calcium oxide and yttrium oxide. The higher Mohs hardness is, thehigh quality gem gets, and generally Mohs hardness scale is 8.0~8.5.
Its appearance and luster is similar to diamonds. But the hardness is much lower than diamonds so it could go cloudy. CZ is the best substitute for diamonds and cheap, so it is usually used in fashion jewelries. In TATIAS titanium ring, we normally use Swarovski Signity White Stone as a CZ,
