One would think that no chromium-rich minerals would grow next to emeralds.
This Cr-bearing variety of pyrophyllite comes from San Gregorio, a locality known for producing the most intense green emeralds of the Chivor mining area.
Host rock is black shale.
| Mineral: | Pyrophyllite (variety Cr-bearing), Pyrite |
| Locality: | | Chivor mining district, San Gregorio Mine, Municipio Chivor, Eastern Emerald Belt, Boyacá Department, Colombia | |
|
| Dimensions: | 117x72x27mm |

Elongated, translucent double terminated crystal, on a partly oxidized black shale host rock.
The beryl crystal rests on a druse of light bluish-grey scalenohedral calcite - a very uncommon form in Chivor and in the 2 emerald belts at large.
This well-balanced specimen is from a recent find in the Chivor area but the exact locality name is guarded more closely than a state secret (as usual...).
Best bet is that it's from Palo Arañado mine.

I'm glad you like it Pierre!
Coscuez has a wide variety of crystal forms - elongated prisms are certainly not the most common form.
