Tianzhu is a kind of jewelry produced in Xizang Autonomous Region, China, also known as Tibetan Tianzhu.

Tibetan ancestors believed that the dzi beads were supernatural things created by God, which were naturally generated or descended from the sky. Anyone who says handicrafts is strongly opposed. Ask many Tibetans where the dzi beads came from, and they all tell the same old myth: in ancient times, dzi beads were ornaments worn by immortals. Whenever the beads are damaged or slightly damaged, the immortals throw them along with the biological fossils, which is the same era as Nautilus and trilobites. Some people have presented evidence that the fossil of dzi beads has been seen in the Dingri area of the Himalayas and the fossil mountain in the no-man's land of northern Tibet. The story of the common people goes like this: once a man saw such a bug on the top of the mountain, he threw his hat at it and covered it. When he took off his hat, the bug had petrified and turned into a dzi bead. In his article "Prehistoric Beads in Tibet", Dr. Nebesky Wokowitz told a legend in Ali area in western Tibet. People think that dzi beads originated from a mountain near Ruddock, and they go down the slope like a stream when it rains heavily. However, one day, a witch stared at the mountain with "evil eyes", so the dzi beads stopped flowing at once. Until today, you can still see the distinctive dzi beads with black and white stripes in the place where dzi beads keep flowing out. There are more than a dozen legends about the origin of dzi beads.
