A superb, old-time mimetite (variety: campylite) specimen from the historic Dry Gill Mine of Cumbria. Lustrous, olive-green, curved barrel-shaped mimetite prisms (campylite) richly and thickly cover the undulating matrix of milky quartz. The coverage is about the most I have seen on one specimen. Dry Gill was active as an ore producer from 1830-1869. Fine pieces were recovered in recent times, but this is definitely a 19th century piece. Ex. Robert Whitmore Collection.
