The above is not cameo in question. But is the closest I can find on the Internet. I was in local jewelry store picking up my appraisal for tennis bracelet (will start separate thread for that!) and an antique/estate brooch caught my eye. It wasn't even displayed yet because jeweler doesn't know how to price it. The cameo is the pink shell color and quite large. It is 14 carat yellow gold. But there are diamonds set on sides in the cameo itself like the photo I attached. In all my research, I've seen nothing like it. Wondering if someone added diamonds afterwards like people add diamonds to Rolex dials. If anyone here knows anything about cameos, I'd really appreciate your help. Jeweler promises to call me tomorrow with a price.
