This is one of those ever popular vintage expansion locket bracelets. Marked D.F.B.Co. and Pat. Pend. for the D. F. Briggs Company from Attleboro, Mass. who manufactured this style bracelet until the 1930s I found lot of these for sale. price range $5.00 to $100.00. more like $20.00 to $40.00 would be my guess. being Star of David makes your market even smaller. But that is a good thing, they might pay a little more, just for that. good luck
