A very aesthetic and contrasting specimen of the rare zinc and copper carbonate - aurichalcite. Fine, needle-like crystals of aurichalcite have formed in the fissures and on the surfaces of the highly iron-rich matrix, gathered into characteristic, radiating rosettes. Main Features: intensely blue color; radiating, needle-like rosettes; strong color contrast. Condition: Good. Delicate, needle-like crystals of aurichalcite are scattered over a large surface of the rock. Many of them, especially those hidden in deeper recesses, have retained excellent sharpness and structure.
