Hola Firmo!

Muchas gracias for your kind appreciation.
These ones were recently "found" in the Bogota market which is scarcer than ever.
This shortage is due to a low supply of cut stones which automatically leads to a scarcity of quality specimens on the market for the average buyer.

We need to organize a mine tour on my next visit!

Aggregate of acicular pale-green emerald crystals, with traces of limonite.
This is a very unusual habit for Colombian emeralds.
It was sold to me by the dealer as from Gachalá but after some investigation it appeared that this specimen comes actually from a recent find in the area of San Pablo de Borbur.
When asked on the locality of a recent find, most of the Bogotá-based dealers either don't know or prefer to mislead the buyers by giving approximate or even false information.
This is often part of a long tradition of secrecy to keep the real locality undisclosed.

Very strange beryl - at first glance, I would have said gypsum from Australia. LOL

This forum is really a nice way to enlarge the mineralogical culture.

Thanks

Hello Phlippe!

I was confused too when I saw this specimen.
Hexagonal shape can be sensed for some crystals through magnification.
Green crystalline gypsum is unknown in any of the Colombian deposits.

This forum is definitely a wealth of information and knowledge!

Thanks Michael!
Chivor has often wider and more attractive combinations than Muzo, Coscuez, or La Pita.

The oxidized calcite adds an unusual touch to the traditional color palette of the Colombian specimens.

Beryl crystal literally "embraced" by a druse of laminar albite.
Upper part of the crystal etched.
Unusual beveled termination due to a large contact area.
