In jewelry, "AR 153" typically refers to a specific alloy or metal composition used in the piece. The "AR" often stands for "Alloy Research" or a similar designation, indicating the type of alloy, while "153" could denote a specific formula or standard within that classification. This can provide information about the durability, color, and hypoallergenic properties of the jewelry. Always check with the manufacturer for precise meanings, as terminology can vary.
