WebMay 4, 2024 · It’s sometimes called CZ for short. While naturally occurring cubic zirconia has been discovered, it is extremely rare. Most cubic zirconia is manmade. Cubic zirconia is completel y colorless and is quite hard, with a hardness of 8-8.5 on th e Mohs scale. This sparkly stone can be cut into a variety of shapes.

Therefore, the physical and optical properties of synthesized CZ vary, all values being ranges. It is a dense substance, with a density between 5.6 and 6.0 g/cm 3 —about 1.65 times that of diamond. Cubic zirconia is relatively hard, 8–8.5 on the Mohs scale—slightly harder than most semi-precious natural gems. See more Cubic zirconia (abbreviated CZ) is the cubic crystalline form of zirconium dioxide (ZrO2). The synthesized material is hard and usually colorless, but may be made in a variety of different colors. It should not be confused with See more Currently the primary method of cubic zirconia synthesis employed by producers remains to be through the skull-melting method. This method was patented by Josep F. Wenckus … See more In recent years manufacturers have sought ways of distinguishing their product by supposedly "improving" cubic zirconia. Coating finished cubic zirconia with a film of See more Cubic zirconia is crystallographically isometric, an important attribute of a would-be diamond simulant.
