Physical properties

Hardness: 5-6 (Mohs scale), Color: Pale greenish-white in light, vibrant green glow in dark, Luster: Vitreous/Resinous, Structure: Amorphous/microcrystalline

Formation & geological history

Synthetic creation; manufactured in industrial laboratories. It mimics natural phosphorescence but is most commonly mass-produced from a base of alkaline earth aluminates.

Uses & applications

Primarily used for costume jewelry, decoration, clock dials, safety signage, and metaphysical collecting.

Geological facts

While some natural minerals like Willemite or Autunite are fluorescent or phosphorescent, the high-intensity glow seen in this specific pendant shape is almost always a result of synthetic rare-earth dopants like Europium.

Field identification & locations

Identify by exposing to a UV light or bright sunlight; if it glows intensely for several minutes to hours in total darkness, it is synthetic glow stone. Not usually found in this crystal shape in nature.
