Description

Looking in detail on this matrix specimen, you can find groups of transparent needle quartz, golden pyrite and colored chalcopyrite.

Beneath this lies sphalerite, which has formed beautiful large crystals.

These triangular sphalerite crystals with smooth faces are only noticeable upon closer inspection, as the other minerals have grown on top of them.
