Arizona Azurite - 4259s
Azurite is a soft, deep blue copper mineral produced by weathering of copper ore deposits. The search for mineral wealth defines Arizona’s human history. There is evidence that Arizona’s earliest known inhabitants mined turquoise, cinnabar, coal, and other minerals and pigments as early as 1000 BCE. For centuries, Native Americans used heat to melt copper and shape turquoise into jewelry and other decorations. Over the years, approximately 400,000 mining claims have been filed in Arizona, and about 4,000 companies formed for mining. Minerals drew settlers and explorers, built towns, created railroads, and wowed the world with semiprecious stones.
