2. Diamond simulant - Wikipedia

   en.wikipedia.org/wiki/Diamond_simulant

   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.

3. Cubic zirconia - Wikipedia

   en.wikipedia.org/wiki/Cubic_zirconia

   The emergence of artificial stones such as cubic zirconia with optic properties similar to diamonds, could be an alternative for jewelry buyers given their lower price and noncontroversial history. An issue closely related to monopoly is the emergence of conflict diamonds.

5. Zirconium dioxide - Wikipedia

   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

7. Zircon - Wikipedia

   en.wikipedia.org/wiki/Zircon

   Most gem-grade zircons show a high degree of birefringence which, on stones cut with a table and pavilion cuts (i.e., nearly all cut stones), can be seen as the apparent doubling-up of the latter when viewed through the former, and this characteristic can be used to distinguish them from diamonds and cubic zirconias (CZ) as well as soda-lime ...

9. Diamond (gemstone) - Wikipedia

   en.wikipedia.org/wiki/Diamond_(gemstone)

   A diamond with facets cut only a few degrees out of alignment can result in a poorly performing stone. For a round brilliant cut, there is a balance between "brilliance" and "fire". When a diamond is cut for too much "fire", it looks like a cubic zirconia, which gives off much more "fire" than real diamond. A well-executed round brilliant cut ...
