Key features of cubic zirconia distinguish it from diamond: One face of an uncut octahedral diamond, showing trigons (of positive and negative relief) formed by natural chemical etching. Hardness: cubic zirconia has a rating of approximately 8 on Mohs hardness scale vs. a rating of 10 for diamond. [1]
The hardness (8–8.5), RI (2.15–2.18, isotropic), dispersion (0.058–0.066), and low material cost make CZ the most popular simulant of diamond. Its optical and physical constants are however variable, owing to the different stabilizers used by different producers. There are many formulations of stabilized cubic zirconia.

Zircon (ZrSiO 4) and cubic zirconia (ZrO 2) are cut into gemstones for use in jewelry. Zirconium dioxide is a component in some abrasives , such as grinding wheels and sandpaper . [ 49 ] Zircon is also used in dating of rocks from about the time of the Earth's formation through the measurement of its inherent radioisotopes , most often uranium ...
Ceria-zirconia is widely used as a component in current three-way catalytic converters. [6] The ceria-based component of the converter has several functions, including promoting the dispersion of the noble metals in the catalyst, but also storing and releasing oxygen. [ 7 ]
