Cassiterite after Orthoclase$675.00




Wire transfers available, to set up
A loose twinned crystal of what was once orthoclase now replaced by cassiterite. In good condition all around. A very good example for this famous Cornish pseudomorph specimen collected in the 1820s. The specimen comes with an antique label as shown at the end of the video. Note that this label gives a collection date in the 1840s, I do believe these were collected earlier. There is a slight fracture line as seen in the picture and video, this is completely natural and the piece is very solid. It is more of a growth feature than anything.
