This superb old classic millerite has a large spray of golden-metallic crystals showing, embedded in the chalcopyrite matrix around it. The tips of the freestanding crystals stick out the top of the piece, showing that this is not a contact cleavage fragment but rather a natural grouping of intact crystals enmashed partly int he matrix. Note the beautiful old original label from Carl Bosch, dated on the backside May 13, 1909. He prided himself on his German classics suite and it was all donated to the Smithsonian, from which this specimen was later exchanged out.
