This cabinet specmien consists of a rusty limestone base on which rest scores of tiny native Copper crystals. These crystals do not exceed 1 or 2 mm in diameter and are generally in excellent condition, showing almost no damage. When viewed with a loupe, one can see reasonably good tetragonal and octahedral forms, along with some intergrowth and even some possible twinning. All have the standard bright coppery red color and metallic luster. They rest on a black oxide coating that partly covers the base. Oddly enough, there are not even visible traces of any secondary copper minerals on the piece.
