Very fine indeed! Such a transparent and lustrous gwindel is a treasure for every quartz collector like me, and that it's from Mt. Blanc makes it even more desirable. And though I like older finds with a "classic" touch, I love the fact that this is a recent find from this summer!

Great piece, Philippe!

Quartz
It was very difficult to have a photo of this one (poor lighting, poor skills, poor background, and so on ... and totally water clear)

Please, can you clarify the exact locality.
I have Penas Blancas Mine in Santander Department
but Penas Blancas seems to be in Boyaca Department

It has many horizonal striations on the prism faces, and I would say it is Muzo habit.

Bonjour Philippe !

If this is Colombian, it's likely from either San Cristobal pegmatite, Suaita Municipality, Santander Department
or
Peñas Blancas Mine, San Pablo de Borbur Municipality, Boyacá

Bergur could provide more insights than I on this one.

Gérard.

Either Muzo or Tessin, a magnificent crystal.

Hi Philippe.

I would bet on Peñas Blancas Mine.

I believe surely someone has confused the department.

PostPosted: Nov 15, 2021 10:09    Post subject: Re: Collection of Philippe Durand  

The way the crystal is broken at the bottom is typical of Peñas Blancas
(not from extraction, they are broken like that and encrusted in limonite and more, then treated with acid to get them clean)
I'd say that Belleza/La Playa area in Santander is a possibility as well, but most likely Peñas
...and as Firmo suggests, someone may have gotten confused with depts.

Peñas Blancas isn't technically a single mine but a whole mountain in Boyaca.
It has many small workings from quite low down though most are higher up.
Different areas produce different things, and the quartzes come mostly from some of the higher areas worked (as far as I know)...as do the fluorites from there.

Thank you a lot for your input Gérard, Bergur, Firmo, Sante :)
I had no doubt that our Colombia specialists could have the answer.
so if a gentle administrator could enter the Penas Blancas locality, it would be great :)

thank you Dany
the specimen is better than on the photo (crystals going in front of the camera that I can not catch ...

it is a relatively new specimen (just a couple years ago)
