Vintage Mother Mary And AB Glass Rhinestone Adjustable Ring

I’m unsure what kind of metal the ring is has wear but can be expected with vintage items. Sparkly AB rhinestones and ring is adjustable somewhat I don’t think I would want to bend it too much as it could break. I would say it could be adjusted up to a size 7 it’s about 5.5 now if you adjusted down to a 4 I don’t think it would look right. Lovely old ring
