Hi, Dany.
Thank you, I'm fine, although waiting for the vaccine...
As far as I know, needle quartz often occurs with the Dauphiné habit in Val Bedretto (and many other Alpine localities).
It is not difficult to distinguish it. A rhombohedral face (of the termination...) is quite larger than the others, sometimes a little and sometimes a lot, creating in the second case, a so called flute beak shape.
I'm sure now you will find some among your Alpine quartzes. Good luck.
Stay safe.
Sante

For example, in the needle quartz from Bedretto Valley that you posted on july 10th 2019 there are many. :-)

Hi Dany,
are you sure, that your last needle quartz is really quartz? I am quite sure, that I see some dovetail twins, and also the overall habit makes me think of gypsum. What is the hardness of these crystals?
Maybe I am wrong, my eyes sometimes are not that good as I want.

I agree, it looks a lot like Gypsum

Thanks James, Jordi and Volkmar.
You're right. "The Chinese Fluorite won the fight against the Swiss Gypsum". You must not always trust the seller.
Could someone change the mineral name and keep only Switzerland for the provenance ?
Have a nice Sunday and keep safe.

Sorry Dany,
Your first hematite (with quartz) is not hematite, but nice silvery muscovite plates, as far as I see.

Thank you for your message. I need to be more careful and still to learn a lot.
Have a nice day and keep safe.

| Hi Dany, I'm sorry to have some doubts that this specimen is from Dalnegorsk. Sure, there are many many kinds of fluorites and combinations with sulfides from that giant deposit. But it is one of my favourite localities and I must confess that I never saw anything like that from Dalnegorsk.
No guarantee, just a doubt!

Hi Dany,
I had a similar thought to Tobi when I first saw your fluorite from Dalnegrosk. I have been a collector of Dalnegorsk minerals for more than 30 years and I have never seen a combination specimen of fluorite and pyrite like this. The spherical pyrites on the fluorite make it look more like the ones from El Hammam Mine in Morocco. Nice specimen in any case.
Michael

Similar fluorite combination with pyrite is also found in Moscona Mine, Asturias, Spain.

I agree with Michael and Josele, Moscona and El Hammam were my first thoughts, maybe also Freiberg ... maybe you could provide a photo of the matrix?

HiTobi, Michael and Josele,
I had some doubts too when I posted the photo. I'll take a picture of the back this weekend.
Thank you for your comments.
Have a nice evening.
