Why not wear 925 silver?
925 silver is a beautiful gray metal. In human history, silver has long been a very popular jewelry material because of its smooth and white, fresh and elegant style and moderate price. However, the traditional silver jewelry has a fatal weakness, which is easy to oxidize. A beautiful silver ornament often begins to turn black and lose its luster after being worn for several months.
Therefore, in recent decades, with the popularity of gold, platinum and diamond jewelry, traditional silver jewelry began to be gradually ignored. In fact, the real 100% silver is white, soft and will not turn black, but because silver is rarely produced in the form of monomer, purification requires special smelting technology, and pure silver is too soft to be molded.
Therefore, in traditional silver jewelry, other metals have to be added in a certain proportion to increase its hardness and ductility. For example, the most popular so-called pure silver 925 is actually alloy silver with 7.5% copper or nickel added. But this kind of silver products mixed with other metals is actually the real reason why silver jewelry is easy to turn black.
