Unusual Art Deco Black and White Cameo Pendant with Black Enamel Accents on Metal

Unusual black and white cameo in navette or marquise shape with a gold tone frame with black enameling. I love this unusual shape and the frame is exquisite. The black stone looks like onyx but i believe it is plastic or maybe jet as it has no temperature. The white is plastic or celluloid.

In excellent to like new condition.
