Swarovski are well-crafted, high quality, man-made crystals. How is made: Originally the crystals were composed of silica, an alkali, and lime. Then 32% Lead was added to create a better quality crystal that withstands cutting and engraving. A special metallic chemical coating is added to create a rainbow spectrum or many different colors. Origin: Swarovski is a well-known brand within the luxury jewelry business. Daniel Swarovski invented the formula for the crystals in the 1890s. Most Swarovski crystals are made in Austria. Energy: Hung in windows, crystals can bring chi energy from outside into dark areas of your home or office. A crystal placed in the south-east, north-west, or center of a room can aid in stimulating prosperity.
