Ultra rare "Anhydrite tubes"
in Smoky Quartz
1.8 x 0.6 x 0.5 cm
One of the most rarest things to find in the Alps. One 5mm long tube goes throug the crystal (you can look through it), another 10mm long is semi-closed, as you can see on the pictures. And there is a 3rd one of 4mm, but also semi-closed.
I found this in summer 2002 within a vein at the Schwarzhorn, that had about 60 single crystals, but only 2 with Anhydrite tubes. One I keep for my collection, the other one I offer to you. In literature, I just found one Anhydrite tube specimen descripted, but that wasn't with Smoky Quartz.
