Quintinite-2H from Iron mine, Kovdor Massif, Kola Peninsula, Russia

Orange hexagonal crystals to 1.5mm. The locality is probably one of the better localities of just a handful reported worldwide. This geo-environment is more like a skarn than a carbonatite as in Jacupiranga. The crystals display perfect basal cleavage giving the appearance of a micaceous mineral but is not.
