Calcite (twin)

These Tri-state twins are always such a treat to see. Save for the bottom, there is no damage, and the translucency is quite good. I love the frosted appearance at the V notch on one side and the Y formation on the other side. Tiny sphalerites(?) are embedded on several faces. Ex Jim and Paula Wilson.

Locality: Tri-state Mining District, Picher, Oklahoma
