Killer crystals of this amazing rare species, from the type locality! This is a 2.8 x 2.3 x 1.5 cm type locality specimen for Corkite. Collected in a fairly risky underground exploration to abandoned old mines here in the summer of 2019 by Robert Lawson (Allanton, Castle Douglas, Scotland, UK) co-author of the article: “The Mineralogy of Glandore Mine, County Cork, and a Re-Examination of Corkite from this, the Type Locality.” An exceedingly rare phosphate analogue of Beudantite within the alunite supergroup.
