Moolooite, Whewellite & Humboltine on Copper ex Vajdak Coll.

Item Description

The extremely rare organic oxalates moolooite (copper-rich, bluish-green), whewellite (calcium-rich, white) and humboldtine (iron-rich, amber-yellow) are richly scattered as crusts on all sides of the sculptural, floater, native copper specimen from the Ahmeek Mine of Copper Country. To find all three of these rarities on the same piece is very rare for this locale. Ex Josef Vajdak Collection. Not pretty to look at, but is still a significant Michigan combination rarity. Value???
