Well formed green gemmy to translucent cubic crystals of Pharmacosiderite are seen to abundantly cover two cavities on the display face of the specimen, from Wheal Gorland, St. Day, Cornwall. Crystals of Pharmacosiderite measure to nearly 2mm. On the reverse and under side of the specimen are also to be seen just as well formed crystals of Pharmacosiderite, but much more scattered. A Ferruginous Quartz matrix is the host for the Pharmacosiderite crystals.
