I do not know much about it. I got it in a storage unit, after doing some search on google it looks like it's Art Deco but I do not know for sure. It is stamped 10K on the inside but I do not know how much of it is gold or if it was plated as it has the appearanceof silver. It is a very nice ring and just needs some cleaning up but please keep the previous facts in mind. For more information please message me.
