Azurite

Unknown Owner

A brilliant blue crystallized mass of azurite.The Bisbee mining district, located in the Mule Mountains of Cochise County, Arizona, is one of the most celebrated mineral localities in North America. Geologically, the area is famous for its massive replacement deposits where copper-rich hydrothermal fluids interacted with the Paleozoic Escabrosa Limestone, creating spectacular secondary oxidation zones filled with azurite, malachite, and cuprite. Historically, the district's industrial era began with the filing of the first claims in 1877, leading to the formation of the Copper Queen Consolidated Mining Company. For nearly a century, Bisbee was a powerhouse of production, transitioning from high-grade underground operations to the massive open-pit mining of the Lavender Pit in the 1950s. Major corporate operations, primarily under Phelps Dodge Corporation, continued until the mid-1970s, with the Copper Queen Mine and the Lavender Pit officially closing in 1975 due to declining ore grades and rising costs. Today, Bisbee remains a legendary site for both its historical role in the American Industrial Revolution and the world-class mineral specimens that continue to define the standard for copper carbonates in many museum collections.
