Rather fantastic and unusual. Super gilt decorations on true cranberry glass. The bowl the tumbler/cup sits in is about 6 1/4" diameter, 2 5/8" to the rim, and the cup is about 4" tall and 2 7/8" wide. When assembled they are 5 1/4" tall assembled. Excellent overall condition. Has some roughness to inside rim of cup, as made. Both the base of the tumbler and bowl are cut flat and polished. Not sure who made it, but it is very high quality. About 170 years old too. Love the gilt.
