Crystal not only has its own high quality and sophisticated production process, but its appreciation and collection potential can not be ignored.

Crystal products like the Stone Age have basically become rare treasures, but they are difficult to identify and expensive. Therefore, the risk of collection is relatively large. Followed by the crystal rough. Crystal rough stone has a certain collection value, and it is relatively simple to collect.

"In the identification, generally use optical instruments such as magnifiers, polarizers, etc. Natural crystals are transparent like water, have a distinct cool feeling, crystal inclusions are solid, liquid, and artificial crystals are white in color, only slightly cool, The crystal inclusions are needle-like or breadcrumbs, and even rough workmanship may even have bubbles or impurities."
