The 3 Graces Sterling Silver Blue Agate Cameo Pendant is a stunning piece of vintage jewelry featuring a beautiful blue agate cameo set in Sterling Silver - though please note, the metal is NOT marked. I purchased this like 15+ years ago and am recalling the metal type from memory... and it was expensive back then, so I'm not sure why it isn't marked, but if you purchase it, please understand I have not tested the metal type.
