S925意思

"S925" is a hallmark or quality mark used for sterling silver jewelry and items. It indicates that the item is made of 92.5% pure silver, which is the standard for sterling silver. The remaining 7.5% is typically an alloy, usually copper, which is added to the silver to increase its hardness and durability, making it suitable for use in jewelry and other objects.

The "925" number refers to the fineness of the silver, meaning that out of 1,000 parts, 925 parts are pure silver, and the rest is the alloy. This mark is often found on silver items, especially those imported from countries like Italy, where the use of a hallmark is mandatory for items made of precious metals.

When you see "S925" or just "925" stamped on a piece of jewelry, it means that the item is sterling silver and has met the standard for purity set by the industry and various regulatory bodies. This mark helps consumers identify the quality and purity of the silver, which is important for both the value and the authenticity of the piece.
