2.7" Atacamite & Druzy Quartz Association - Peru

This fantastic specimen contains an association of druzy quartz crystals and vivid green atacamite. The atacamite looks to have formed large crystal clusters, only later to be coated in an aggregation of druzy quartz crystal. It was collected from the Lily Mine in Pisco Umay, Peru and is 2.7" wide.

It comes with an acrylic display stand.

Atacamite is a secondary copper mineral that's formed from the oxidation of copper minerals. It has the chemical formula Cu₂Cl(OH)₃ and forms as slender prismatic crystals, fibrous crystals and as granular to compact aggregations. Atacamite was first described by D. de Fallizen after specimens found in the Atacama Desert of Chile in 1801.
