Colourless to white bubbly Allophane covers much of the Pyrite rich specimen from Wheal Hamlyn, near Bridestowe, Devon. Associated with spherulites of Malachite and Ferruginous Quartz. A rare Devonshire specimen from this little known copper mine on the edge of a Limestone Quarry near Bridestowe. It is not certain which quarry the mine is near, as there are two near Bridestowe, and one a little further away.
