Digenite, Djurleite

Digenite and djurleite are both sulfides of copper. While seemingly simple in chemistry, they are both complex structurally. Breithaupt (1844) named the mineral after the Greek for both, since the mineral seemed to contain two valences of copper. Morimoto (1952) named djurleite after Dr. Seved Djurle (1918-2000), Professor of chemistry at Uppsala University, Sweden, who first synthesized the compound. This specimen shows the characteristic matrix of the benitoite locality, with blue schist rock veined with white natrolite. The natrolite has been partially removed by acid treatment to reveal complex digenite crystals to 5 mm and smaller tablets of djurleite to 3 mm. The djurleite has a black alteration on its surafce, while the digenite crystals are sharper and metallic gray. Digenite is rare at this locality.
