Dates to very early 20th century and just wonderful examples of what I describe as a light enameled marquetry glass or cameo glass light. Transparent decorations and stellar to look at too. About 4 3/8" underplate and 3 5/8" diameter cup/stem. This could be a nut cup, a bon bon dish? And a hard glass to make as there are not many of this quality.
