this ring, I have researched and can find no information other than it was more than likely handmade in india. it is heat stamped 18k. I did show it to a friend who's a pawnshop owner and he said it appears to be gold. I cannot authenticate that and am not paying for an appraisal that being said, this beautiful probably hand hammered ring is near perfect I soaked it in vinegar, did the makeup and float test. no tarnish, no discoloration. I'll let someone else do the footwork probably one of a kind and very old according to some antique sights if it isn't real it's high quality
