Uranium glass - Sphere/Orb - 12 mm

Uranium Glass Sphere - Orb – 12 mm - UV Reactive Bead

These stunning 12 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.
