Cassiterite pseudomorph after Orthoclase

ID: CC21590
A charming thumbnail pseudomorph of Cassiterite after Orthoclase Feldspar from Wheal Coates at St. Agnes on the north coast of Cornwall, due north of the town of Redruth.  Although only tiny, measuring 1.4 cm long, the pseudomorph is sharp and well defined, displaying nicely the original Carlsbad twin.  These famous specimens were found around 1828 and are a mixture of Cassiterite and Quartz in varying proportions, this specimen appearing Cassiterite-rich.  It is accompanied with a Maurice J.E. Grigg label which states ex. the collection of Sir W. Sargeant.  The specimen comes in a small card box with a beautifully written label, presumably in Sargeant’s handwriting.
