What does 925 mean on jewelry

 925 is a common hallmark that you may see stamped on jewelry, especially silver jewelry. It refers to the purity of the metal used to make the piece. Specifically, 925 refers to sterling silver, which is an alloy made up of 92.5% pure silver and 7.5% other metals, usually copper.

Sterling silver has been used for centuries to make jewelry, flatware, and other decorative objects because of its lustrous shine, durability, and relative affordability. However, pure silver is too soft to be used in jewelry on its own, so it is often combined with other metals to create a more durable alloy.

The hallmark 925 indicates that the piece of jewelry is made with 92.5% pure silver and 7.5% other metals, usually copper. This ratio of silver to other metals is considered the industry standard for sterling silver. Jewelry made with sterling silver is often stamped with the hallmark 925 to indicate its quality and purity.

It is important to note that not all silver-colored jewelry is made with sterling silver. Some pieces may be made with other metals such as nickel, which can cause skin irritation in some people. To ensure that you are buying sterling silver jewelry, look for the hallmark 925 or ask the seller about the metal used to make the piece.
