2. Cubic zirconia - Wikipedia

   en.wikipedia.org/wiki/Cubic_zirconia

   In 1977, cubic zirconia began to be mass-produced in the jewelry marketplace by the Ceres Corporation, with crystals stabilized with 94% yttria. Other major producers as of 1993 include Taiwan Crystal Company Ltd , Swarovski and ICT inc. [ 8 ] [ 5 ] By 1980, annual global production had reached 60 million carats (12 tonnes) and continued to ...

3. Zirconium dioxide - Wikipedia

   en.wikipedia.org/wiki/Zirconium_dioxide

   In jewelry making, some watch cases are advertised as being "black zirconium oxide". [24] In 2015 Omega released a fully ZrO 2 watch named "The Dark Side of The Moon" [25] with ceramic case, bezel, pushers, and clasp, advertising it as four times harder than stainless steel and therefore much more resistant to scratches during everyday use.

4. Zirconium - Wikipedia

   en.wikipedia.org/wiki/Zirconium

   Zirconium dioxide (ZrO 2) is used in laboratory crucibles, in metallurgical furnaces, and as a refractory material [13] Because it is mechanically strong and flexible, it can be sintered into ceramic knives and other blades. [51] Zircon (ZrSiO 4) and cubic zirconia (ZrO 2) are cut into gemstones for use in jewelry.

5. Yttria-stabilized zirconia - Wikipedia

   en.wikipedia.org/wiki/Yttria-stabilized_zirconia

   Yttria-stabilized zirconia (YSZ) crystal structure. Yttria-stabilized zirconia (YSZ) is a ceramic in which the cubic crystal structure of zirconium dioxide is made stable at room temperature by an addition of yttrium oxide. These oxides are commonly called "zirconia" (Zr O 2) and "yttria" (Y 2 O 3), hence the name.

6. Diamonique - Wikipedia

   en.wikipedia.org/wiki/Diamonique

   Logo used since 2010. Diamonique is the brand name used by television shopping network QVC for their cubic zirconia simulated colorless diamond, simulated colored diamond, and simulated colored gemstone jewelry (cubic zirconia is a common type of gemstone substitute). [1]

7. Diamond simulant - Wikipedia

   en.wikipedia.org/wiki/Diamond_simulant

   Cubic zirconia can be coated with diamond-like carbon to improve its durability, but will still be detected as CZ by a thermal probe. CZ had virtually no competition until the 1998 introduction of moissanite (SiC; silicon carbide). Moissanite is superior to cubic zirconia in two ways: its hardness (8.5–9.25) and low SG (3.2).
