Lab Created Diamond vs Imitation Diamond

Lab created diamonds should never be confused with white stones such as cubic zirconia (CZ), moissanite, and other inexpensive imitations. These stones do not have the same chemical, optical, thermal, and visual properties of diamond. Only lab created diamond is exactly the same as a mined diamond. 

A diamond, whether mined or lab created, is the hardest substance known to man (ranking 10.0, the highest level on the Mohs Hardness Scale). Jewelry containing mined or lab created diamonds can be worn every day and passed on to heirs because of diamond's incredible durability.
