Native copper is a mineral that occurs in nature in the metallic state of copper (Cu), without being bound to other elements. Such minerals are called "elemental minerals" and are not found in large quantities due to limited conditions for their occurrence. The crystal system is cubic, and they occur in a wide variety of forms, including massive, linear, crusty, and dendritic. They are known to form in particular in voids within basalt and at contact points with sedimentary rocks.

With a low hardness of 2.5 to 3 and excellent malleability and ductility, native copper is known as one of the earliest metals used by humans. Another major feature of native copper is that it can be processed as is without refining. It is also sometimes found as a secondary mineral along with malachite and azurite in the oxidation zones of copper deposits. Please enjoy the weight and texture unique to metallic minerals, and the appearance of "copper itself" created by nature.

This is a single piece of native copper (as shown in the photo), weighing an average of 22 carats.
