The chain has an English hallmark does the heart lock closure. The thirteen hearts are all different, some vintage and a couple appear to be earlier. DAISY, HARRY, MA, DADDY, INTIALS RB, JW, YT, AND JOSIE. Some puffy and some flatter, a great bracelet. At present it measures about 7 1/2 inches but any jewelry could add few rings if you need it larger. It also has a safety chain. It would be a good idea to have a jeweler solder the ring holding each heart.
