The "970" stamp on a necklace indicates that the piece is made of 97% pure silver, which means it is a high-quality silver alloy. This designation is less common than the more typical 925 (92.5% silver) and is often used for more premium or specialty silver items. The remaining 3% typically consists of other metals, such as copper, to enhance the alloy's strength and durability.
