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 ...

6. Ceria-zirconia - Wikipedia

   en.wikipedia.org/wiki/Ceria-zirconia

   The crystal structure adopted by ceria-zirconia depends on the Zr/Ce ratio and temperature. At very low Zr concentrations, ceria-zirconia exhibits the cubic fluorite structure, which is common to both pure ceria and cubic zirconia (pure zirconia normally only adopts a cubic structure at high temperatures). However, at higher Zr contents, other ...

7. Zirconium dioxide - Wikipedia

   en.wikipedia.org/wiki/Zirconium_dioxide

   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). This state of zirconia is commonly called cubic zirconia, CZ, or zircon by jewellers, but the last ...
