Here is some information about crystals.
Is glass that has Lead (in the form of lead oxide [PbO]) in its chemical composition. The purpose of Lead Oxide is to increase the density of glass, which in turn, increases the refractive properties, luster, and clarity of the crystal. When it is cut and polished, it creates more colors and sparkle in light than regular glass.
The higher percentage of Lead Oxide in the crystal composition, the more vibrant the colors are reflected and refracted from it. Cutting and polishing techniques are also very important. In the old days, they were cut and polished by hand, which left scratch marks and imperfections on the surface of the crystals. Today, with the use of computer controlled, high-precision machinery, crystals are cut and polished to perfection, just like diamonds, to achieve the maximum amount of sparkle and luster.
