St. Austell District, Cornwall, England
An old Cornish classic, this pseudomorph is a complete and sharp replacement of the original twinned Feldspar. No damage or missing areas, this is a perfect floater. Textbook form much like a crystal model. Sometimes called "pig's ears" these are not "beauty" type display minerals but they are distinctive and unique to these old finds. Not many turn up for sale, this one is the best and sharpest example we have seen available.
