A fine classic specimen from the Tintic District, ex Northwestern University Museum, Charles Noll, David Crawford etc. Bright Cuprian Adamite crystals sparkle against Azurite and Conichalcite on a gossan matrix with traces of Cuprite. Comes with several labels, is in fine condition, undamaged, and clearly a very old specimen. Almost never seen on the market today, from a significant US locality.
A rich vug of nearly pure Cornwallite surrounded by Azurite. Outstanding form with fine and distinct sheaves and spherical masses. With several old labels dating to the late 19th century, (Erinite was the old group name for Cornwallite and Chalcophyllite). Dense coverage with no damage, an unusual and attractive USA specimen of this uncommon Copper mineral.
