Interesting artisan-made piece connects bracelet and ring to create what is commonly called a slave bracelet. This one features a cloisonné butterfly on a white heart. The white background is enamel; butterfly is filled with tiny chips of deep red stone. The motif is the same on bracelet and ring.
The hand shown in the first photo is small; there is not as much slack on the chain between the ring and bracelet.
Both ring and bracelet are marked ©USA G&S 86 and the ring is marked 8, which is the size. Metal is silver tone with a high copper content; the inside diameter of the bracelet is 2-1/2” at its widest point, with a 1-3/8” opening. Very good vintage condition.
