Are Lab-Created Diamonds the same as Cubic Zirconia?
Lab-Created Diamonds are 100% pure crystallized carbon, which makes them optically, chemically, and physically identical in every way to an earth-mined diamond.
Cubic Zirconia is made of synthetic zirconium dioxide in its crystalline form and is commonly used as a low-cost alternative to a mined diamond; it has absolutely no presence of carbon diamond bonds in its creation, it is simply a crystal cut in a way to mimic the look of a diamond. The lack of crystallized carbon is why Cubic Zirconia (CZ) differs chemically, physically, and optically from an earth mined or Lab-Created Diamond.
