Is s925 silver pure silver? What should I do if the s925 necklace turns black?

S925 silver is a mark on many jewelry. S925 silver is actually pure silver. Its brightness and luster are closer to platinum. The quality is very good and the silver content is 925 thousandths of silver.

S925 silver is not pure silver. The difference between it and pure silver is the silver content. The silver content of S925 silver is 92.5%, and the rest is 7.5% copper. Because the hardness of silver is relatively low, if pure silver is used to make jewelry, it is easy to deform when worn. 925 silver has a higher hardness, so the jewelry made of it is not only as good as pure silver in appearance, but also has a higher hardness, so it is very common.

When we buy a necklace, there is usually a silver polishing cloth given with the necklace. Be sure to keep it well because it is the best tool for cleaning. If you find that the necklace has become black, wipe it with the silver polishing cloth and it will become brighter.

2. Use toothpaste

Squeeze toothpaste onto an old toothbrush, then rub the blackened area. After rubbing, wipe it clean with a soft cloth. Do not get it wet during the entire rubbing process.

3. Use white vinegar

Prepare a towel, then dip it in vinegar at home to wipe the necklace. After wiping back and forth, the blackened area will gradually become brighter.

If you don’t control the soaking time well, it will easily cause the necklace to lose its color. So if the blackening is severe, you can find a professional organization for maintenance.
