Swarovski Diamonds are in fact Simulated Diamonds that are made by Swarovski and called their Pure Brilliance Collection. It is the first simulated diamond to adhere to the Gemological Institute of America (GIA) rigorous standards for grading diamond cut quality. GIA is the world’s leading authority for diamond grading and assessment. Each Swarovski simulated diamond is marked with a microscopic engraving that is completely invisible to the naked eye. The laser engraved quality seal allows one to identify the authenticity of each stone giving you the confidence that they are of the highest quality and brilliance.
The American Gem Trade Association defines a Diamond Simulant as: “A man-made single crystal, which can be manufactured with different materials and designed to simulate the appearance, but not duplicate the characteristic properties of a natural gemstone.”
Due to the superior quality it is nearly impossible to tell the difference between a real diamond and a Swarovski simulated diamond. The brilliance, sparkle and luster look virtually identical and have the characteristics of a colorless Ideal cut virtually flawless diamond.
