Beautiful Earth Tone Color Cameo Necklace and Earrings Set

Very unusual and rare…Cameo necklace and earring set. Chain measures 16”, cameo pendent measures 1 1/4”. Earrings measure 3/4” not including wire earring. These do not have any markings that are visable. The lady is a tan/caramel color shell with a glimmering mother of pearl background. The metal around it is both gold tone & silver tone combo. This beautiful set is “vintage” and belonged to my Grandmother.
