   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]

4. Carat (mass) - Wikipedia

   en.wikipedia.org/wiki/Carat_(mass)

   The carat (ct) is a unit of mass equal to 200 mg (0.00705 oz; 0.00643 ozt), which is used for measuring gemstones and pearls. The current definition, sometimes known as the metric carat, was adopted in 1907 at the Fourth General Conference on Weights and Measures, [1] [2] and soon afterwards in many countries around the world.

5. Diamond simulant - Wikipedia

   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.
