The number of weathering patterns on the surface of agate is related to the wearing habit. If there are more collisions during the wearing process, the weathering patterns will be correspondingly more. It is not easy to knock out the weathering patterns if the texture is tight. On the contrary, the texture is thin. Weathering patterns are easy to collide, which is why on the agate of the same age, some beads have more weathered patterns and some have less weathered patterns.
