A sample of native (naturally-occurring) copper. Native copper usually occurs in compact, filiform or dendritic masses, although tetrahexahedral or octahedral crystals are occasionally found. Copper is a soft, heavy, ductile, maleable, pinkish-red metal. It is an excellent conductor of heat and electricity, and is used in electrical cables and wires and in alloys such as brass and bronze.
