Roman glass pendant

This pendant is made from a round piece of Roman glass. Its bezel set in sterling silver has an open back. It’s super sparkly, really pretty. It measures just over 3/4 of an inch around and with the ring for the bale just shy of 1 inch in length. This glass cannot get wet. This is brand new. I’ve never worn it. I tend to put on my necklaces and wear them 24/7 and I’m afraid I’ll forget to take this off, and ruin it so that’s why I’m selling it.
