Hi. I am hoping someone recognizes this hallmark. The piece is a well made amber bracelet in sterling silver. Every link is hallmarked with what looks like a pumpkin or apple with initials J K separated by a symbol of some sort. Even the tab near the clasp is shaped like a pumpkin or apple. Its probably well known, just not to me. Sorry, I can't seem top get the photos to load properly, but these links seem to work. Thanks in advance for your help.
