Large silver heart with a string of silver balls necklace

Large silver heart centerpiece for a necklace of silver beads I left it unpolished, I like it warm colored, but I remember it on my very fashionable mother polished it bright silver and very modern in the 1960’s Heart is 1 1/2” with the string of silver beads 16” long It is missing a bead? I don’t know. The string shows a little in the back of the head, see picture. Otherwise it is in excellent condition
