Electroplating is generally divided into electrogold and platinum. The way to identify electroplating is that its surface is brighter than pure silver, like a mirror, with good reflective effect and less oxidation.

First, the silver jewelry you are wearing is not real silver, but may be silver-plated products. After wearing for a long time, the silver water on the surface of jewelry will expose the metal inside and turn black.

If there is a seam, brush it with a toothbrush to prevent foam from entering the seam; If it is a stone embedding process, avoid the toothpaste from contacting the stone, and finally rinse it off, especially where there are cracks in the hollow.
