Description/Interesting Notes: A large and impressive old time example of kaolinite after orthoclase from Cornwall!!! This specimen consists of a group of several intergrown, twinned orthoclase crystals that have been completely replaced by kaolinite!!! This specimen is complete and in fantastic condition all around!!! The crystals exhibit characteristic twinning and have sharply defined features!!! This large and impressive old time pseudomorph displays fantastically in person!!! These unique pseudomorphs were known to miner's as "pigs' eggs" (although I am not sure why this is)!!!
