Are the Swarovski crystal color names, such as Topaz mean that it is made of the semi-precious gemstone Topaz?
No. All of the crystal color names are referring to the color, not the mineral composition. Swarovski crystals are considered to be the finest quality, full-lead crystal made today. It contains a minimum of 32% PbO (lead oxide), making the crystal optically very pure. The crystal is then faceted with tremendous precision, creating beautiful prisms. Brilliant colors and/or coatings are added to the crystals to create pendants, stones and beads of dazzling beauty. Swarovski crystal is unmatched in quality and distinction. When genuine semi-precious gemstones are used in creating the pieces it is stated in the product description.
