Mineralpedia Details for Aurichalcite
Named for the Latin word for “brass,” aurichalcum, which itself comes from the words for the colors gold, aurum, and copper, chalceus. Aurichalcite is a relatively common mineral with hundreds of widespread, worldwide localities including as good specimens from Russia, Italy, Greece, France, USA, Mexico, Iran, Namibia, and the Democratic Republic of the Congo. Aurichalcite can be found in oxidized copper and zinc deposits in association with rosasite, smithsonite, hemimorphite, hydrozincite, malachite, and azurite.
