Lab grown/created diamonds have the same physical, chemical, and optical properties as mined diamonds, and exhibit the same fire, scintillation, and sparkle. But lab grown/created diamonds are a responsible choice given that no mining is required. Lab grown/created diamonds offer excellent value, and are slightly more affordable than natural diamonds.
Lab grown/created diamonds can be distinguished from natural diamonds only with tests using specialized equipment. Lab grown/created diamonds available for purchase should always come with a gem certification identifying them as laboratory grown.
