Brochantite from Milpillas Mine, Mexico
from the Milpillas Mine is one of the great modern surprises in copper-mineral collecting: a species long appreciated as green sprays and crusts, suddenly appearing from Sonora in sharp, lustrous, display-quality crystals of exceptional color and scale. Milpillas is better known to many collectors for its azurite and malachite, but the mine also produced brochantite that serious species collectors routinely compare with the finest known examples for the mineral.
