Calcite, with strong "brief intense phosphorescence" - Estrie, Quebec, Canada

Updated: Jul 12, 2021

This calcite specimen, with the typical red fluorescence (best MW, then SW, then LW, as it's often the case with red fluorescing calcites), is not quite exceptionnal. But I still thought it was worth showing, first because fluorescent calcites from the Estrie region (formerly "Eastern Townships") are not often shown online, but also because it has a stronger than usual "brief intense phosphorescence" upon exposure to longwave.


I remain vague on the locale because the occurrence where this specimen was found was discovered by a friend of mine, who asked me not to disclose it.


Size: 7,7 cm X 6,7 cm X 2,7 cm
