Definitely Not. They are totally different materials. Diamonds are made entirely from carbon, whereas cubic zirconia contains no carbon! CZs have a different light performance and pattern and are much weaker than diamonds structurally. Any jeweller can easily tell the difference between a diamond and a diamond simulant such as CZ or moissanite.

There are some websites who are selling CZ’s stones and calling them ‘Synthetic Diamonds’. This is untrue and fraudulent.  There is little policing of such practices which could protect the consumer so unfortunately it is a case of ‘buyer beware’. Adamastar Diamonds would never claim our diamonds are other than what they truly are – actual diamonds.
