A stunning and highly beautiful contrast of black, white and vivid green, I like it :-)

Thanks for your nice comment Tobi.
This is a good example of the typical bluish-green hue found in some of the Chivor crystals.
This color is rarely seen in the crystals from the Western Belt (Muzo, Coscuez, La Pita, Peñas Blancas).
This also explains why the Chivor faceted stones are less sought-after than the Muzo/Coscuez/La Pita ones which have generally a much higher green saturation.
Useless to say that these are just general trends and there are many exceptions to this 'color rule' in both belts.

Cubic pyrite, calcite, 20+ emerald aggregates in parallel growth, set on a druse of sparkling white granular albite.
Host rock is an albitite rock i.e. a whitish albitized black shale matrix.
From a recent find (May 2018).
