Now gold is generally sold in pure gold, but silver jewelry is different! Many of them are 925! The purity of silver jewelry is S990, thousands of feet of silver and pure silver. These (925 S990, thousands of feet of silver, pure silver) are just the purity of silver ornaments. Generally, the buttons on the silver jewelry necklace and the back of the bracelet at the bottom of the ring are marked, which is no different from the special gold shop, but large supermarkets and shopping malls will sell 925! ~
