Cubic Zirconia

Cubic zirconia, also known as CZ, was created as a more affordable alternative to genuine diamonds.  Cubic zirconia is the best synthetic stone of all  diamond´s substitutes. It comes in every imaginable colour and at a fraction of the cost of other gemstones.

 Zirconia is an ideal raw material for the production of jewellery thanks to its hardness comming close to the  hardness of ruby or sapphire, and optical properties close to those of diamond.

 

The cubic zirconia stones  are available in following colours:
