Needle brochantite crystals on a set of quartz crystals, which are covered by goethite.

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.
