I bought one like that and it's called a cocktail ring. The one I bought was marked 14K. When it was tested, it came out the bottom ring part was only 10K solid gold, but rater thin. It was miss-marked on purpose and the wiring part that held all the stone settings were all made from gold filled wire. It was made to deceive it was. I gave like around $35. for it, but was still able to sell it for close to $50.00, so I wasn't duped at all really, but I sure thought I was when I found out what it really was after I purchased it. The only real way you'll ever know what you actually have is to take it to a jeweler and have them give an opinion OR you could take up Jeff's offer to help? The age I'm thinking is later 50s early 60s a style some refer to as hollywood regency imo.
