This has a small bail, so it will need a smaller end on a chain, or any jeweler can attach it for you. The pendant isn’t small; it is a larger pendant weighing 18.6 grams and featuring a white coral branch mounted in solid sterling silver. I think the patina looks amazing, so I left it as is. It measures 2.25 inches tall by 1 1/8 inches wide. It has no hallmarks or signatures but is fully tested by my jeweler. This is an amazing one-of-a-kind estate piece!
