What does ATI 825 mean on your jewelry?

ATI 825 on jewelry typically indicates the material used in its composition. "ATI" refers to the manufacturer or brand, while "825" signifies that the piece is made of 82.5% silver, which is commonly associated with sterling silver. This indicates a high-quality silver alloy, as sterling silver is usually composed of 92.5% silver and 7.5% other metals, such as copper. Thus, the "825" marking suggests it's a different alloy, possibly indicating a specific type of silver or a controlled blend.
