Swarovski® is the brand name for a range of precisely-cut lead crystal (a particular type of glass). Swarovski® Crystals are precision - cut lead crystals that are created through an innovative patented technology by Swarovski® A.G. While normal crystal glass contain only 12-28 % lead oxide to increase light refraction, Swarovski® crystal contains approximately 32% lead oxide. This increased lead content refracts light more efficiently, hence adding more lustre and sparkle to each crystal bead. The lead content also increases the weight of the crystal as compared to normal glass. Swarovski® implements the strictest quality control in its manufacturing process and has a benchmark of 98% accuracy and consistency in the quality of its end product.
