This is a wonderful sweetheart expansion bracelet produced by one of the best companies out there - Pitman and Keeler. They have been in business since the early twentieth century. The center of this bracelet was patented in Edwardian times. The date is Nov. 6, 1907. However, they did not produce this particular type of band until later in the century. I find it very exciting that they used one of their early designs for this bracelet. There is a lovely engraved floral around the outside of the center and a heart at the very bottom. This bracelet has never been engraved so you can have your name or initials put on it. If you decide to personalize it the jeweler can remove the minor wear marks on the centerpiece. There is a heavily embossed design on every other link and the links are tight. Bracelet will expand to fit most wrists. The center is 1" top to bottom and bracelet is in excellent condition.
