The state is the type locality for a large number of mineral species (over 100), including many rare and unusual minerals that are of particular interest to systematic and advanced mineral collectors.
Colorado is internationally renowned for the diversity and quality of its mineral specimens, especially those from classic mining districts such as Leadville, Cripple Creek, Ouray, Silverton, and the San Juan Mountains. The state has produced world-class specimens of rhodochrosite, fluorite, amazonite, smoky quartz, silver, and gold, many of which rank among the finest examples known.
Rhodochrosite is the state mineral of Colorado, officially designated in 2002. Aquamarine is recognized as the state gemstone, while Yule Marble is designated as the state rock.
The Rhodochrosite of Sweet Home Mine is a hot pink-red, and likely the best in the world for crystalline rhodochrosite, sometimes in association with quality Fluorite. The state is also known for excellent specimens of native silver and gold, high quality Amazonite and Aquamarine, and fine Garnet.
Colorado has yielded exceptional alpine and pocket specimens, particularly quartz, feldspar, and fluorite crystals from high-elevation localities, as well as historic precious-metal ores.
In addition to its mining heritage, Colorado is home to geological and mineralogical sites that are popular with tourists.
These include areas such as the Florissant Fossil Beds National Monument, Great Sand Dunes National Park, and the Garden of the Gods.
Colorado exploits a broad range of mineral resources including molybdenum, gold, silver, coal, uranium, industrial minerals, construction aggregates, and gemstones. The state also plays an important role in the production of minerals critical to modern technologies, including those used in renewable energy and advanced manufacturing.
