Spiroffite - Sold

Spiroffite is a manganese tellurite. The mineral name honors Professor Kiril Spiroff (1901-1981), Bulgarian-American mineralogist at Michigan Tech, Houghton, Michigan, USA. Mandarino (1962) first announced the species and its complete description followed in Mandarino et al. (1963).

The manganese content of spiroffite imparts a rose red coloration to the species. This example has cleavage plates to 6 mm on a fragment of bull quartz matrix. This specimen came out in 2007, when exploration for gold around Moctezuma enabled collecting of a ton or two of tellurate bearing rock.
