This is a large specimen with one face partially covered by crude to formless dark orange Andradite (EDS). Amongst the Andradite are tiny red spheres of an unknown mineral. These crystals are likely covered by Quartz, imparting a crystal ball-like appearance. I have not bothered to test these, and have chosen to leave these to your imagination.
