Crystal is a form of glass that has 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. When it is cut and polished, it creates more colors and sparkle than regular glass. The higher percentage of Lead Oxide in the composition of crystal, the more colors are reflected 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 equipments, crystals are cut and polished perfect just like diamonds to achieve the maximum amount of sparkle and luster.
