Barbara Bixby Enhancer Key Pendant in Blue Topaz (does not include the chain; can be purchased separately). Beautiful intricate design in Sterling Silver with 14KT Yellow Gold flower accents. Can be worn on a chain without opening the enhancer or you can open the enhancer part to put onto a strand of pearls or beads. I have had it stored away for a long time and even forgot I had it. It is in Excellent Condition and has hardly even been worn. I just don’t wear jewelry often even though I love it and have collected it for years! I am the original owner.
