Sternbergite - Sold

Sternbergite is a silver iron sulfide, named by Haidinger (1827). The mineral name honors Caspar Maria Sternberg (1761–1838), Czech botanist, of the National Museum in Prague, Czech Republic. Sternbergite forms stubby black crystals to 1 mm in a dense aggregate 1.2 cm across on this specimen. Peacock (1936) performed a morphological study of sternbergite and made line drawings. Later work by Czamanske & Larson (1969) showed the polymorphous relationship between argentopyrite and sternbergite. Later, Pertlik (1987) solved the crystal structure.
