Azurite  

MXA74CD4: A historical piece. Fine sharp tabular Azurite crystal aggregate with very visible flat faces of very brilliant luster and intense blue color forming rosettes crisscrossed with each other. The specimen stands out both for its good size as well as for its origin, the primitive 'Mine Bleu' opened by miners in 1811, and which yielded numerous vugs full of Azurite, as evidenced by this specimen.
