Haven't had any luck id'ing this piece.
Opaque / Ivorene style exterior with an iridescent oil spot finish and red threads. Interior is transparent red. Ground circular pontil mark, the pic of the full on base isn't great, some reflections (the finish is a clean circular /somewhat oval grind). Fine contact wear on the foot ring edge.
6 3/4" h x 5" w
Came from an estate with some older stuff, French cameo, but that doesn't mean anything.
Vintage 1920's or yesterday's studio (?) any ideas.
Thanks!
