“This small cabinet specimen hosts soft purple colored, sharp, lustrous, gemmy cubic crystals of fluorite which are associated with starkly contrasted black prismatic crystals of ferberite plus a gentle coverage of golden muscovite crystals and some small white albite(?) crystals. The largest fluorite measures 1.7 cm on edge and the largest ferberite measures 2.5 cm. Ex Dr. Stephen Smale Collection. Along with amassing one of the finest private mineral collections in the world, Steve is a renowned mathematician. His accomplishments include being awarded the Fields Medal in 1966 along with being the awarded the Wolf Prize in mathematics in 2007.
