So going through my boxes (can you tell I'm bored?) I found that one. I bought it many many years ago in Vienna from an antique store. I just liked it. I just knew that I love jewelry, but didn't know much else about diamonds an Co. I hardly ever wear it (maybe I should...). However, I was wondering if anyone might be able to date it. Art Deco? The diamonds are so tiny I can not see their cut. It is stamped 585.
