2. Cubic zirconia - Wikipedia

   en.wikipedia.org/wiki/Cubic_zirconia

   Cubic zirconia [also known as cubic zircon) is crystallographically isometric, an important attribute of a would-be diamond simulant.During synthesis zirconium oxide naturally forms monoclinic crystals, which are stable under normal atmospheric conditions.

3. Diamond simulant - Wikipedia

   en.wikipedia.org/wiki/Diamond_simulant

   Its low cost and close visual likeness to diamond have made cubic zirconia the most gemologically and economically important diamond simulant since 1976. A diamond simulant, diamond imitation or imitation diamond is an object or material with gemological characteristics similar to those of a diamond.

4. Zirconium - Wikipedia

   Zirconium is a chemical element; it has symbol Zr and atomic number 40. First identified in 1789, ... Zirconium Hazards NFPA 704 (fire diamond) 0. 1. 0. ...

5. 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).
