This is an old Onganja specimen from the old dealer stock of Gary Hansen. You can see sharp faces on the malachite-coated cuprite crystals. The crystals are not complete on the sides, but this allows you to see the glassy interiors of the cuprites (which are actually a very deep red). In addition to these two copper minerals, the Onganja is known for some fine crystallized copper specimens. 4.6 x 3.2 x 2.3 cm
