This is a really super fluorite example from this classic American locality. The fluorite crystals are a deep purple colour with rich yellow undertones that are fabulous when backlit.
The scalenohedral calcite crystals are a lovely adornment and accent the piece very well.
Lots of interesting growth patterns and plenty to keep you enthralled for hours.
I added this to my collection soon after Peter Seroka , who had a superb fluorite sub collection, dispersed it before he moved from Germany to the US.
There are breaks to the back and underside consistant with removal from host matrix.
