Material: Colored Copper Silver Plated Crushed Silver+Natural Freshwater Pearl+Natural Stone This silver chip material was electroplated with multiple layers at home, and the color retention effect is very good. The diameter of the beads is also made in the smallest size, not the very large ones. It has no foreign object sensation when worn and will not cause finger strain. Pearls with high quality and few flaws are better. Theft of images will be investigated
