Calcite with Hematite Inclusions

I pulled this large cabinet piece out of my collection only due to space limitations. I acquired it when Buck Keller passed away (formerly in his collection). There are some missing crystals and I have considered trimming it, but it is a survivor from a storied find, so it is what it is. The largest crystal is 2.7cm.

Locality: Banana Slide Fault Zone, Beckermet, Egremont, Cumbria England

Composition: Calcium Carbonate and Iron Oxide
