The vintage heart padlock clasp on this vintage bracelet is hallmarked for London 1960 with a maker's mark that looks like T.B. The front of the padlock and each of the twisted links are also stamped 9 375 reflecting the 9 karat gold content. The bracelet is comprised of twisted oval links, each about three sixteenths of an inch wide with a circular link at each end to hook the padlock heart clasp that is joined to the rest of the bracelet with a fine safety chain. In total the bracelet is approximately 7 and a half inches long and will fit a seven and a quarter inch or smaller wrist. The padlock clasp can be a bit awkward at first until you get the hang of it but well worth the effort. The bracelet looks stunning on its own and can be enhanced with charms of your choosing. It is in excellent condition with only minor signs of age or use, weighs 9.2 grams. A terrific gift for yourself or someone special.
