If you've ever looked at jewelry and noticed a "925" stamp, you might wonder what it means. The number 925 is a hallmark that indicates the piece is made of sterling silver. Understanding what 925 means can help you identify quality jewelry, make informed purchasing decisions, and properly care for your silver pieces.

Key Takeaway: What Does 925 Mean on Jewelry?

The number 925 on jewelry means the piece is made of sterling silver. Sterling silver is an alloy consisting of 92.5% pure silver and 7.5% other metals (typically copper). The "925" stamp is a hallmark that certifies the silver content, ensuring the jewelry meets the standard for sterling silver. Pure silver (99.9% silver) is too soft for most jewelry applications, so it's mixed with other metals to create a more durable material. The 925 stamp is a quality mark that indicates genuine sterling silver, helping you identify authentic pieces and avoid plated or fake silver jewelry. Understanding this hallmark helps you make informed purchases and properly care for your sterling silver jewelry.
