In 1892, Daniel Swarovski invented the automatic crystal cutting machine. With the technology he opened a factory in Austria. Rhinestones, or Swarovski crystals, contain over 30% lead, which gives them an extraordinary shine. The crystals are also coated with metallic chemical layers, creating a dazzling shine. Coverings include Northern Lights, Crystal Transmission, Dorado, Volcano, and Aurum. The Swarovski brand continuously develops different types and colors of crystals.
