Cubic millimeter boleite crystals covering the entire sample. On both sides of the sample can appreciate the deep blue crystals, excellent sample for a microscope or showcase.
Group of octahedral crystals of bornite truncated at their tips in calcite matrix and andesite. Another isolated hexagonal chalcocite crystals appear accompanying the bornite.
This is a very large and relatively thick sheet of natural silver, that is still attached to a chunk of bornite ore. Both the ore and the silver have a beautiful, colorful iridescence.
Silver wires with a bright patina are perfectly dispersed across a heavy matrix of eerily iridescent, purplish-blue bornite, accompanied with vein of chalcopyrite.

Spectacular chrysocolla geode covered by a layer of needle-shaped bronchantite urchins. This sample was collected around 2010 and is one of the finest extracted from this famous mine. Video of the specimen on Instagram
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.
Calcite crystals from this classic mine, featuring a single, semi-translucent, perfectly terminated crystal on a matrix of other crystals and earthy iron oxides.
Thousands of small colored crystals of caledonite cover the sample on both sides and accompanied by yellow-brown chlorargirite crystals and a bit of gypsum bark in the matrix.
