Anatase
Tälli glacier, Albrunhorn - Turbhorn area, Binn, Goms, Valais, Switzerland
A bicolor crystal, brown in the two end portions and gray-black in the central part, of anatase. It should be noted that the pinacoid, in its right side, has a bevelled edge due to the presence of the dithetragonal bipyramid. Collection and photo of Gianfranco Ciccolini.
