Black Kyanite from Ribeirao de Folha, Minas Gerais, Brazil. These black kyanite fans with their radiating symmetry and silky luster seem to me to be often overlooked at gem shows and other markets. But they certainly hold a striking beauty, especially when multiple fans intersect as in this larger combo piece. A mineral curiosity to be sure and inexpensive as well!
