Description/Interesting Notes:
A fantastic, 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!!! These specimens are quite difficult to come by today and we have acquired every
one we have ever come across!!! This specimen consists of a sharply twinned orthoclase crystal that has been
completely replaced by cassiterite!!! Although the specimen is not fully complete, it is doubly terminated with sharply defined
features, significantly sized, and displays fantastically in person!!! The sharpness
and detail are much more significant then they appear in the pics!!! Upon close inspection one can see some
eye-visible crystals of cassiterite embedded within the crystals' surface!!! Interestingly, the crystal shows some unusual
features suggestive of some kind of concentric growth - as there is a second twinned termination visible in the v-shaped notch on one end!!!
As one would expect, this specimen has considerable heft for its size as well!!! These
rare specimens are considered to be "Holy Grail" pieces among Cornwall and pseudomorph collectors!!! Simply a magnificent example of this rare and highly sought
after classic!!!
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!!!
