Phosphorescence (in the common meaning of the term) seen by naked eye:

No Data


Most fossils are composed of calcite, aragonite or crytocrystalline quartz (chalcedony) or even opal. All these species can be fluorescent and form beautiful samples of fluorescent fossils: mollusk shells filled with calcite crystals, fossil corals with very decorative patterns, silicified wood, internal turret molding in chalcedony, belémnite in calcite / aragonite or in opal, etc. .

Main Activator(s) and spectrum:

Most Common Activator: Organic impurities

Other activators:            (UO2)2+ (Uranyl ion) as impurities ,

No spectrum for the moment
