First-class crystal grade - PYRIT xx with high-gloss SPHALERIT xx.
This specimen comes from an old find from the famous HUANZALA mine in the Peruvian Andes.
Very well formed PYRIT crystals with the typical, characteristic striation, with many SPHALERITE = ZINC BLENDE - sitting on crystals.
We photographed these steps in the shade, in the sunlight the shine is so intense that the camera (and we have a very good one) can no longer reproduce it properly.
Weight of this beautiful crystal step: 1.4 kilograms
Size: 14.5 x 10 x 6 cm xx up to 2.5 cm edge length
The last picture shows the underside of the step, also with many xx with beautiful end faces!
