The most fabulous cameo we ever owned in our collection! Tested 18K yellow gold mounting in a brooch design, the original mounting for this museum quality hardstone cameo in black and white, surrounded by genuine Persian turquoise. It is 1 & 5/8" tall and 1 & 3/8" wide and in very good condition. It appears to be a one piece cameo, with very finely detailed carving of a beautiful lady with tall ruffled collar and pearls necklace; and she is facing left, a rare design. On the top of the back is a small tubular piece that may have originally housed a swivel loop for hanging; your jeweler can easily add one again is desired. This is truly a one of a kind piece and we think a fabulous design; with the interplay of the black and white with the turquoise as a lovely framing accent. A true heirloom to be enjoyed and passed down for generations to come.
