Buenavista mine produces among the finest beryl crystals in the Chivor area.
Prisms are often dihexagonal.
Some of the matrix is a brown, brecciated mixture of calcite with layers of iron oxide, covering the black shale.

Hi Gerard. This emerald crystal has rather unusual facets. How often do you find such as these? IMG_7236nb.JPG

Hi Pierre,
Dihexagonal prisms are pretty uncommon in all districts.
I have only seen a handful of those in 20 years.
There is a similar prism (also from Buenavista) posted on page 10 (towards the end).
Another example - from Muzo this time - is visible on page 17 (first post).
That's about all the dihexagonal prisms I have in my collection :-(

This specimen is from one of the most significant finds of the last decade in the Chivor district.
Unfortunately these photos do not do justice to the exceptional quality of the beryl crystals.
It's a true miracle that some specimens from this find (I have seen a dozen or so) have escaped from their natural fate.
Host rock is black shale.

Definitely Pierre!
By the time I started working seriously on the inventory my backlog was already (very) bad.

Back to green pastures...
The beryl crystal (etched) is sandwiched between a calcite and pyrite crystal.
Host rock is grey shale.

From a recent find in Chivor.
Specimens from this find are easily recognizable for their elongated crystals and complex "step-like" terminations.
Host rock is black shale.
