Cassiterite pseudomorph after Orthoclase Wheal Coates, St Agnes, St Agnes District, Cornwall, England 2.42cm x .72cm x .71cm Ex. Sal Avella Collection

Description/Interesting Notes: A classic, old time example of this highly prized pseudomorph from Cornwall!!! These old cassiterite after orthoclase pseudomorphs came from a small, one time find in Wheal Coates around 1828 and have been highly sought after by collectors ever since!!! This specimen consists of a sharp orthoclase crystal with a second tiny orthoclase crystal perched on its termination - that have both been completely replaced by cassiterite!!! Upon close inspection one can see that the crystal appears to be a baveno twin!!! Additionally, with a loupe or scope one can see the minute, darkly colored crystals of cassiterite that this prized pseudomorph is comprised of!!! This specimen has considerable heft for its size!!! These old time, historic specimens are extremely difficult to obtain!!! Don't miss out on this rare opportunity!!! This specimen is from the personal collection of Sal Avella!!! The pics hardly do it justice!!! Must be seen in person to be fully appreciated!!! Good luck and be sure to check out my other exciting mineral auctions on ebay!!! STAY TUNED!!!
