Artificial crystal is containing lead oxide in the glass, the higher the composition of the lead oxide, refractive index and the higher the hardness, the finished product is the more the pure crystal, the harder it will be cut at the same time, finished products will be rare.High quality glass rhinestones ware with ordinary glass or low diopter of crystal value difference is very big. 1, listen to the voice: hand recoiling vessels will sound different when, artificial crystal products, crisp like a metallic after will feel well fills the air, "dang dang" sound with a metal ring, the higher the hardness of crystal, the louder sound.And the voice of the glass is boring, no echo, "snapped" sound is more boring.

At present, in circulation of homebred man-made crystal mostly produced in pujiang county, zhejiang province, the product materials for K9 or leaded material, crystal products fine workmanship, jade-like stone light and refined, cold light.
