Item Description

Vivid blue spherical aggregates of tiny cyanotrichite needles with complimentary botryoids of powder-blue chalcoalumite richly cover all sides of the sculptural small cabinet matrix crust. This very colorful and uncommon combination is from the old and extinct Cu-U Grand View Mine, which was only active from 1893-1907. The mine lies within the current boundary of the Grand Canyon National Park and is off limits for over 20 years, to collectors. Ex Allen Dillwith Collection. Classic and desirable Arizona combination material.
