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.

It is a piece with tiny crystals but bullies, I would not mind having a piece so small.

Thank you Jose Luis - I am assuming "bullies" is the English translation for "muy bueno".
These crystals are indeed small but muy bueno - they are so bright!
