2. Cubic zirconia - Wikipedia

   en.wikipedia.org/wiki/Cubic_zirconia

   Cut: Cubic zirconia gemstones can be cut differently than diamonds: The facet edges can be rounded or "smooth". Color: only the rarest of diamonds are truly colorless, most having a tinge of yellow or brown to some extent. A cubic zirconia is often entirely colorless: equivalent to a perfect "D" on diamond's color grading scale. That said ...

3. Zirconium - Wikipedia

   en.wikipedia.org/wiki/Zirconium

   The most common oxide is zirconium dioxide, ZrO 2, also known as zirconia. This clear to white-coloured solid has exceptional fracture toughness (for a ceramic) and chemical resistance, especially in its cubic form. [37] These properties make zirconia useful as a thermal barrier coating, [38] although it is also a common diamond substitute. [37]

4. Zircon - Wikipedia

   en.wikipedia.org/wiki/Zircon

   The natural color of zircon varies between colorless, yellow-golden, red, brown, blue, and green. The name derives from the Persian zargun, meaning "gold-hued". [10] This word is changed into "jargoon", a term applied to light-colored zircons. The English word "zircon" is derived from Zirkon, which is the German adaptation of this word. [11]

5. 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.

7. Gemology - Wikipedia

   en.wikipedia.org/wiki/Gemology

   Gem identification is basically a process of elimination. Gemstones of similar color undergo non-destructive optical testing until there is only one possible identity. Any single test is nearly always only indicative. For example: The specific gravity of ruby is 4.00, glass is 3.15–4.20, and cubic zirconia is 5.6–5.9 . So one can easily ...
