I was so excited to find these vintage glass pieces with the gold backing intact. So many times when I go searching through bins the gold backing is all beat up and the pieces are unusable. But these were perfect and the result is a lovely glowing pink piece. They matched so nicely that I had them made up into hook clasps. These have two rings. Think how nice they would look with pearls. The clasp is 34 mm from ring to ring. The centerpiece is set in a handmade sterling silver clasp. The hook doubles back on itself for a very secure closure.
