Description

An extraordinary, rare „native“ copper-aggregate of the Bolivian locality „Corocoro“ This interesting piece shows a kidney shape and because of the weathering, it shows it’s fantastic coloring: an intense green-cyan, which is typical for chrysocolla. Good Bolivian Coppers are not common on the market and therefore this green- coated branching sheet of copper is really something special!
