What other materials are referred to as being diamond like?

CZ Cubic Zirconia In Production since 1976

Many people that read this informative research paper will in all likelihood remember the (CZ) Cubic Zirconia a manufactured cubic crystalline zirconium dioxide. While this can come in colors it is best known for being hard and being very clear or colorless.  Doping is used because of the cubic zirconia isomorphic capacity mixing with other elements. There are 15 colors, in all you can make 15 distinctive colors of cubic zirconia’s.

Because of the low cost likeness to diamonds, synthetic cubic zirconia gems are still a viable gemological and economically viable alternative to the high priced natural diamond but this statement is less true for the laboratory diamond industry. The basis of this polycrystalline ceramic zirconia derived from cubic zirconium oxide made for a great use in refractory it can resist high temperature to melt, so it is highly resistant to thermal and as well chemical attack.

Rhinestones (high-leaded glass) both are human made gem materials. Two others strontium titanate and synthetic rutile (neither in current common use).

Laboratory developed moissanite is becoming somewhat more popular in usage. Moissanite has a hardness of 9.25 on the Mohs hardness scale and so you are in the know, a diamond, the hardest natural material on earth is a 10 on the Mohs scale.
