This is a miniature French cameo art glass piece. The function might be as a shot glass or toothpick holder, or perhaps there is no function at all other than for display. The date is the Art Nouveau Period, circa 1890 to 1910.
The glass is 1 7/8" high and 1 3/8" wide.
The piece is not signed by the maker. However the French glassmakers who produced similar glass during this time period are the Patin Cristalleries, Galle and Daum Nancy.
The base layer of glass is the clear-white glass favored by the French glassmakers. The over layer, or the cameo layer, is a purple glass. The purple cameo glass is raised up and the design is one of leaves, stems and flowers.
The rim is flat with no beveling. One side of the mouth is thinner than the other side. The bottom is flat with some of the purple glass.
There are no nicks, chips or cracks. There is age wear on the bottom. The photos show a lot of estate dirt.
