Wheal Gorland near the village of St. Day in Cornwall was a treasure house of fine copper and iron arsenate minerals. Despite not being the Type Locality (that falls jointly to Tincroft mine and Carharrack mine in Cornwall) the world's finest crystals of Pharmacosiderite were found there, in the Wheal Muttrell section of the mine in the very earliest years of the 19th century. Most crystals occur in shades of green, with the most sought after being a deep bottle-green colour. This rich miniature specimen displays oxidized Quartz veinstone containing numerous cavities lined with glossy green cubes of Pharmacosiderite up to 2.5 mm on edge, with golden internal reflections. Minor greyish-blue to colourless Scorodite crystals occur in assocation. Ex Udo Harms collection.
