UTC Gold 925 Sterling Silver Ring Size 8

UTC Gold Vermeil 925 Sterling Silver Ring. Like new condition. This ring was a gift to me and is absolutely beautiful. The main stone looks like an emerald (not confirmed by a jeweler). I can't wear it because it is too big for me. It looks to be a size 8 (or close to it) based on my sizer. Please see photos. I would keep it for myself if I could wear it. Stamped "UTC 925 THAI." Very pretty ring.
