Cyanotrichite
Cyanotrichite is a Copper Aluminum sulfate and well-crystallized specimens like this one are few and far between. It was found in the mid-1960s in the Grandview mine, which existed in the Grand Canyon. The mine is long defunct, but when specimens were being recovered, they were some of the most incredible, and brightly colored specimens from Arizona, or anywhere else for that matter. This specimen is filled with dozens upon dozens of excellent, bright blue color, acicular (needle-like) radiating aggregates or "sprays" of Cyanotrichite associated with dark green Brochantite, lighter green Malachite, pale blue Chalcoalumite and rich blue Azurite. There is also a small tabular colorless crystal which is most likely Gypsum or Baryte. The needles of Cyanotrichite are very delicate, but are equally stunning to view. Ex. Richard Kosnar Collection.
