Aquired this beautiful sample from a vintage collection.
Group of Adamite clusters in Limonite matrix, with another botryoidal mineral i wasnt able to ID yet
//origin: Ojuela mine, Durango, MEXICO
//size: 7 cm ( 3 inches )
//weight: 165 g
//UV: 365 nm
Acquired one of my dreams, an exceptional Adamite cluster on Limonite, from a vintage collection.
Under 365 nm UV light.

My grandfather worked in oil drilling industry, and collected a ton of interesting samples from the sites he worked at. I think the matrix is some kind of schist, but i have no clue about the crystals.
There is a label that says “pirrhotin”, but i think thats a stray label belonging to another sample…things got mixed a bit
It was collected in the 70s , most likely in Hungary, or another neighbouring soviet satellite state
I have a lot of samples that i would like to ask for your help with, but i dont want to flood this subreddit.
So i will post about them in 1-2 week intervals
Thanks in advance 😊
I love this sample, as it’s color is much richer than usual in that region, and for its strong growth zonings.
I also appreciate the almost water-clear , smaller crystals around the edges.

Color-zoning Verdelite Tourmaline in natural matrix ( some kind of Feldspar? )
[size: 56 mm]
[origin: Stak-Nala mine, Haramosh-mountains, Pakistan]
I really love this sample, as it shows how tourmaline occurs within its natural matrix, before it gets separated into single crystals and sold individually
Twin Aquamarine on Tourmaline , with Quartz and Muscovite flakes
[location: Shigar valley, Pakistan]
[size: 65 mm]
I love this sample for its great contrast in colors and statue-esque composition

I have this nice Beryl ( Aquamarine? ) in feldspar matrix.
My question is, do you think the crystal tip/termination is natural, or has it been polished by a human ?
The edges are very straight and sharp, i would be interested to learn the truth.
Thank you in advance !
