I have a Return to Tiffany Mini Heart tag black onyx bead bracelet. Can anybody who has one tell me what is engraved on the back of the heart tag? Mine says T&Co.AG925. But the silver version says T&Co.925.I have a Return to Tiffany Mini Heart tag black onyx bead bracelet. Can anybody who has one tell me what is engraved on the back of the heart tag?
