The number 925 on jewelry shows how much sterling silver is present in the piece. The number describes the parts per thousand. This specific number is most often present on silver flatware, jewelry and tea sets.
This number may occur on other types of jewelry, such as gold and platinum. When this occurs, it shows how much silver is present in the piece because many pieces of jewelry combine two or more precious metals. In the case of gold jewelry with this number, the piece is usually sterling silver, but has gold plating on it, making it appear as a piece of gold jewelry.
