Uranium glass ball

This listing is for one (1) uranium glass ~+/-1" sphere. A beautiful pearlescent peach color in regular light, and glows a bright green under blacklight! ✨ A stunning addition to any curio. Please note that marbles have slight differences, imperfections, and variations! These are vintage marbles and may have small folds from the manufacturing process or small chips.

For hundreds of years, glassmakers used small amounts of uranium to create yellow or green glass. The yellow tint of this glass led to the nicknames “Vaseline glass” and “canary glass.” Under an ultraviolet (UV) or “black” light, the uranium causes the glass to glow bright green
