The weathering lines on both sides of the channel are relatively small, naturally distributed, with bumps and wear marks, as well as small pits caused by drug digging. On the whole, there will be oxidized patina, which is glossy under the lighting conditions, which is impossible for fake beads to imitate! This is a Cuosi threaded bead, and the holes on both sides have obvious traces of knocking and digging, and are full of weathered patina. Why do dzi beads collide? The reason is: Tibetans rarely save money, and they usually carry it with them as jewelry. Grazing, riding and working are all worn around the neck, colliding with each other, and it is also possible to find dzi beads on the grassland.
