A significant East Coast kyanite of display quality! This specimen is terminated (if crudely so as the species usually shows), and is a rare large survivor from these old quarries. It has good blue color, although dampened a bit by the natural brown oxides adhering - though I have chosen not to clean the stains and pocket clay off to preserve the antique look of the piece and thus help distinguish it from Brazilian material. However, it does have associated muscovite, as well, which in person looks quite different than anything Brazil produces with the contemporary kyanite - so I think even if cleaned to spitfire shine, this would be a distinct piece to the trained eye.
