Morenci Mine, Greenlee County, Arizona, U.S.A.
This hand specimen consists of a classic Morenci Mine specimen- scores of shiny Azurite crystals line hollows in a brown host rock. These crystals do not exceed 0.2" (5 mm) in diameter, but are in excellent condition, showing almost no damage. Their monoclinic bladed form is excellent, with straight, well-defined edges and clean faces that possess a bright, almost adamantine luster. Their blue coloration is so dark that it is difficult to determine any translucence, let alone transparence. The cavities that they line are coated with a pale blue, almost white crust that has a dull luster, and sometimes with a dusting of almost microscopic malachite needles.
