Superb complex crystal of blue-black prismatic azurite lying on the classic carious gangue of the deposit. Brilliant crystal, absolutely intact, airy and with a very pronounced color. An exceptional specimen for the locality and for the mineral species.
Such specimens represent a new standard of quality for azurite.
Azurite crystal, from the well known Milpillas deposit in Mexico.
The Milpillas copper mine began operations in 2006. Currently the production is about 26,000 tons of copper metal per year.
