A beautiful sample of chrysocolla on a tourmaline breccia matrix. In the center, a cavity filled with perfectly shaped acicular brochantite crystals can be seen.
Acicular and prismatic crystals stand out for their color and brilliance, covering a large part of the sample. The Brochantite is found in a cavity of chrysocolla and chalcedony druse, a classic feature of this mine.
This specimen is difficult to handle with your hands because it's full of cavities running through the specimen and beautiful acicular brochantite crystals on a druse of chrysocolla. The actual specimen is much better than the photographs.
