Vintage HINGED BANGLE Bracelet-Green Cabochon retailer (Jade?) Signed FS

Up for bid is a fine sterling and green stone hinged bangle bracelet, signed FS. It is made of round silver wire, flattened on the bottom, with a hinged cabochon stone mount with a hook and eye closure. It has an internal circumference of 6 ½ inches and weighs 14 grams. I am not sure about the identity of the green stone; it may retailer be jade. It is marked “925” and [FS] in an oval.

Condition on the bracelet is good. There is just normal wear. An attractive silver bracelet!
