This is a Bohemian art glass vase, frosted white satin glass, decorated with gold enamel and a cameo face. The date is the 19th century, circa 1890.
The shape is tall and slender, on a round pedestal foot, and a tapered neck that flares into the mouth.
The vase is 10" high and 2 7/8" wide at the foot.
The front of the vase is decorated with a gold design in raised gold enamel. There is a carved face of a female face in profile, perhaps a figure from Greek mythology, and the female face appears to be made of solid white glass. The white glass is against an oval of black glass, and the black glass is applied to the vase. Surround the oval of black glass is a circle of amber glass beads.
The rim is flat and beveled slightly on the inside.
There are no chips, nicks or cracks. There was gold trim around the mouth and foot that is mostly worn away. The top of the oval black glass looks like it has a little graze or abrasion from when it was put on the glass. I don't know how the decorative glass was applied to the vase. I can peer inside the vase to the interior and see through where the cameo is on the vase, and I don't see any signs of glue, so it must have some sort of heating process that allowed for the application of the glass decoration.
I do not know who the glassmaker is, don't have a clue, can't even suggest a glassmaker, just know that it is a Bohemian glass vase versus another region.
