Crystal trophy, as its precious value, is an essential award to the great figures in many important occasions.
Crystal can be formed into different colours with the chemical reaction when the temperature reaches to 1400¢J. Different colours will come out from when different metals are added into the raw quartz materials: red colour comes from golden metal, yellow colour comes from silver metal, green comes from calcium, carnelian comes from copper, cobalt makes violet, magnesium makes blue, Li2O3 marks marble.
Artificial crystal derives from SiO2, PbO and other materials then heated with high temperature. PbO (Lead Oxide), which is called Lead Crystal, has higher reflective effect, hard and high gravity. The higher content of PbO, the higher purity and spectrum will be formed. With its complex forming procedures and high technology, the artificial crystal is much more expensive than the natural one
