The jade collar-shaped vessels excavated from the Jinsha site fully reflect the distinctive characteristics of Jinsha jade on the jade: the internal structure of the jade is relatively loose, porous, and easy to weather, and the inside of the material is mostly white, gray, light yellowish brown and other basic colorless series, but the surface of the utensils mostly shows rich and colorful colors such as red, purple, brown and black. This phenomenon is mainly due to the adsorption of foreign metal ions and organic matter, so this alternating, charming, and extremely moving natural pattern will be formed on the surface of the jade.
