This specimen has two nice sphalerite crystals (one on top, the other on bottom), plus a scattering of small ones. The sphalerite is nearly transparent. In some places, I can see into the crystal for some depth (with the aid of a loupe). The sphalerite is reddish-brown in color, and in a few places I can see a characteristic red flash in the crystal. The host rock is composed (or at least covered) with tiny white opaque prismatic quartz crystals.
