Bruce Museum Collection 2019.4.49 Gift of Robert R. Wiener

Malachite gains its rich green color from copper, and was used to produce pigments for thousands of years. Malachite can be found in many forms, ranging from rounded botryoidal clusters, to fibrous deposits, stalagmites, and rarely crystals. This specimen shows the classic silky texture found at the Milpillas Mine in Sonora.
