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

No Data


De Ment make an association between the name collinsite and quercyite a discredited name today (carbonate-rich hydroxylapatite donker than collinsite).

Collinsite is sometime associated with scholzite;

Most Common Activator: Organic impurities

No spectrum for the moment

Comments on activators and spectra:

Collinsite from François Lake, BC, Canada is associated to bitumen which could be the cause of fluorescence.
