Cubic zirconia (CZ) is a popular and affordable stone loved
among jewellers. It is a man-made synthetic crystalline substance and often used
as an alternative to other gemstones. Because Cubic Zirconia is grown in a lab
in a controlled environment, if the crystal is not perfect in clarity, it is
simply not used. Cubic Zirconia’s have a hardness rating of 8.5 on the Mohs
scale which brings it close to matching the hardness of diamonds which are a
perfect 10. They are also approximately 75% heavier than diamonds.
