Miniature, 4.1 x 3.3 x 3.0 cm
Bou Azzer, Morocco

While this fairly uncommon, cobaltoan arsenide occurs in deposits around the world, it is rarely found in exceptional crystals like this one, which is jauntily perched on a matrix composed of drusy skutterudite. The modified cube of brilliant, metallic silver, skutterudite measures more than 2.0 cm across. Just outstanding!
