Horseshoe-shaped dzi beads have small white spots, which may be the discoloration of Tibetan medicine stones. The dzi beads have white spots when worn for a long time. Better show it to an expert. Most of the dzi beads are made of agate, unless the Tibetan medicine stone changes color. Horseshoe pattern is nothing more than the contact between the surface of dzi beads and high hardness materials. If you use it carefully and don't take it out often, it will naturally be used with other jewelry groups with little or no weathering.

Identification method of dzi beads

Looking at the color of dzi beads, dzi beads are generally black and white, dark brown and milky white, and black and white lines are also one of the first choices for many people.

Look at the luster of dzi beads. Surge means that in terms of the intensity of reverse light on the surface, the surge is strong when the reflectivity is high. General surge can be divided into: glass luster, oily luster, waxy luster and earth luster. Due to long-term natural weathering, the surface of dzi beads is not smooth and the reflected light is disordered. Observing the surface with naked eyes, it seems to be coated with a layer of grease, which is called grease luster.

Some oils have a particularly bright luster, which can be called waxy luster. Some dzi beads are baked by fire, and their surfaces are grayish white, which causes some traps for light and is dull. This condition is called earthy luster.

Look at the cinnabar spots on dzi beads. The so-called cinnabar spots are red spots that naturally grow from the inside out on dzi beads, but not every dzi bead has cinnabar spots, nor does it mean that dzi beads with cinnabar spots are good goods. It is just one of the signs to judge the old and new dzi beads, just like the corpse spots in the dark color of old jade.

This erythema may be the result of the fusion of dzi beads and human magnetic field. Because jade itself has permeability, it may be scratched and scratched on the body and bleed, so it will be absorbed into the dzi beads and gradually form blood spots.
