925 sterling silver is the base, not some cheaper base metal like brass or bronze.
The silver is coated with a thick layer of 18k gold to meet a standard of vermeil which means the coating lasts much longer than traditional plated items.
Nickel, Cadmium and Lead free so you won't have an allergic reaction.
This ring is flexible so it's super comfortable to wear!
4mm wide, 1.5mm thick.
