vintage Cameo creations style framed cameo, Incolay jade green & white

Vintage cameo in jade green and white, with a pair of girls dancing.

This is framed and has no visible marks, but is out of the estate of a collector of Incolay, so might be one of their pieces - it looks very much like Incolay to me.

Cameo measures 1 5/8" long, frame is 5 1/4" x 4 1/4" overall.
