Swarovski Crystal Necklace style 189
Swarovski Crystal Necklace style 189 Swarovski crystals are made of quartz sand and natural minerals. The actual product is a form of man-made glass, with a 32% concentration of lead. Although lead is a toxic substance, wearing lead glass jewelry is not harmful to the human body. In fact, the presence of lead is what gives Swarovski crystals the extra sparkle and brilliance.
The Swarovski’s patented cutting machine then allows for a technology-driven cut that creates a high refraction index in the crystals. The machine is so powerful and precise that it can create as many as 100 facets to mirror and bend light in various directions.
After a complex cutting process, a Swarovski crystal is then polished to perfection. Some of the Swarovski products have special coatings. The AB crystals, for example, have a metallic coating that refracts light in a rainbow spectrum.
