RM2415   Covellite

Leonard Mine, Butte, Butte-Silver Bow, Montana, United States of America

Laminar rosette-shaped covellite crystals, excellent luster and with an intense violet to purple color, with an aesthetic iridescence. They are disposed on a matrix with pyrite and quartz. The covellite crystal specimens from Butte are highly appreciated by collectors and possibly the best in the world for the species, with only a few exceptions like Sardinia ones, but even those are not as sharp. The quality of this piece is simply excellent. Nowadays, specimens with this fine crystals are rarely seen.

Size: 9.2 x 8.5 x 4 cm.
Main crystal: 2.2 cm.
Found in ca. 1941.
