The marking “925” on jewelry, including items that appear to be gold, indicates the metal’s composition. It signifies that the item is made of sterling silver, with 92.5% pure silver and 7.5% of other metals, typically copper. A piece stamped with “925” that is also gold in color has been plated with gold, meaning a thin layer of gold has been applied over the sterling silver base.
Sterling silver offers a durable and relatively affordable base metal for jewelry. The addition of alloys such as copper enhances the silver’s strength and malleability. Gold plating allows the item to have the appearance of solid gold at a lower cost. The practice of plating extends the aesthetic appeal of precious metals to a wider audience. Historically, silver has been valued for its beauty and workability, making it a popular choice for crafting intricate jewelry designs.
