What a fabulous piece, a beautiful antique cameo in a necklace mounting, fairly rare to find! First the cameo, a finely carved shell cameo with beautiful lady in fine details and high relief. She is in her original mounting which frames the cameo to perfection with nouveau flower decorations at the top of the mounting. This lovely pendant is suspended on a matching gold tone metal chain, a thick large twisted rope design with wonderful patina. We acquired this from the estate of a fine collection of rare cameos; and we think this mounting and necklace were a one of a kind designed for this special shell cameo. The metal is gold tone with an aged brass appearance, it could be gold filled but we are inclined to think brass or other alloy. The cameo pendant measures 2 & 1/2" tall including the decorative top of the mounting; and the entire necklace measures 13" long laid flat, the chain being nearly 22" around. Truly a masterpiece, and in good condition as well. The cameo back has some discoloration which is only on the back, and we think this occurred when it was made in the process of gluing the cameo into the mounting. We have never seen another piece like this one!
