A lustrous, flattened crystal tree or leaf-like structure of oriented Descloizite crystals in super condition. A textbook example of epitaxial arrangement or stacking. The individual crystals are a dark red color in strong light but in normal light they look black to metallic silvery. The crystals are undamaged, some are also transparent. Great form and sparkling luster, these fine Berg Aukus specimens have become rare in this quality. The Descloizites from this closed mine are regarded as the best ever found and are modern classics.
