2. Cubic zirconia - Wikipedia

   en.wikipedia.org/wiki/Cubic_zirconia

   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]

3. Diamond simulant - Wikipedia

   CZ is made in a number of different colors meant to imitate fancy diamonds (e.g., yellow to golden brown, orange, red to pink, green, and opaque black), but most of these do not approximate the real thing. Cubic zirconia can be coated with diamond-like carbon to improve its durability, but will still be detected as CZ by a thermal probe.

4. Zirconium dioxide - Wikipedia

   en.wikipedia.org/wiki/Zirconium_dioxide

   Like diamond, cubic zirconia has a cubic crystal structure and a high index of refraction. Visually discerning a good quality cubic zirconia gem from a diamond is difficult, and most jewellers will have a thermal conductivity tester to identify cubic zirconia by its low thermal conductivity (diamond is a very good thermal conductor).

   Then cubic zirconia came out, with way more fire than diamonds, more than enough hardness not to get scratched by dust (mostly quartz, Moh's hardness of 7), less colour, more clarity, good resistance to chemicals and thermal shock, less brittleness than diamonds (diamonds chip easily; cubic zirconia can, like corundum/sapphire, actually be used ...

7. Zircon - Wikipedia

   en.wikipedia.org/wiki/Zircon

   Other gemstones also display birefringence, so while the presence of this characteristic may help distinguish a given zircon from a diamond or a CZ, it will not help distinguish it from, for example, a topaz gemstone. The high specific gravity of zircon, however, can usually separate it from any other gem and is simple to test.
