Datolite, calcium boron silicate hydroxide, is a rarity in Copper Country and Copper Falls mine is one of the few places where it is found. This cabinet-sized specimen of Native Copper is also richly invested with white to colourless Datolite, some showing inclusions of Native Copper. The Datolite is crystallized and as crystals, but none are especially well-formed. However, the combination of rich, dense, hackly Native Copper and glassy Datolite is unusual and scientifically interesting. Ex David Hardman collection, no. 2027.
