Cyanotrichite is a Copper Aluminum sulfate and well-crystallized specimens like this one are few and far between. It was found in the mid 1960's in the Grand View 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, electric blue color, acicular (needle-like) radiating aggregates or "sprays" of Cyanotrichite with minor Malachite on matrix. The needles of Cyanotrichite are very delicate, but are equally stunning to view. Please note that there have been almost no specimens from this locality available on the market for a very long time. Ex. Richard Kosnar Collection.
