These stunning 14 mm uranium glass spheres glow a vivid neon-green under UV and blacklight, making them a showstopping choice for jewellery makers, wire wrappers, and collectors alike. In natural daylight they display a gorgeous warm green-yellow hue — beautiful with or without a blacklight.
Why crafters love these spheres
Brilliant UV glow – intense neon-green fluorescence under blacklight or UV torch
Safe to wear – uranium content is lower than typical daily UV exposure from sunlight
Consistent 14 mm size – ideal for pendants, earrings, and wire-wrapped settings (slight natural variation may occur)
Versatile – perfect for wire wrapping, resin casting, macramé, and bead weaving projects
Great value – available in lots of 1, 3, or 5; buy 10 and get an extra sphere free!
