This stunning Green Uranium Russian Vaseline Glass Dessert Coupe Goblet presumably by Fedorovsk Bros GLOWS under UV light. Also known as Canary (Yellow) Flint Glass, this very old glass is in great shape. There's one small chip and various textured areas along the edges and inclusions in the glass, likely from production. The glass is 6" tall and very solid. The bottom is marked 1/4. See photos for details.
