ⓘ Proustite

Proustite is a sulfosalt mineral consisting of silver sulfarsenide, Ag 3 AsS 3, known also as light red silver or ruby silver ore, and an important source of the metal. It is closely allied to the corresponding sulfantimonide, pyrargyrite, from which it was distinguished by the chemical analyses of Joseph L. Proust in 1804, after whom the mineral received its name.

The prismatic crystals are often terminated scalenohedron and the obtuse rhombohedron, thus resembling calcite dog-tooth Spar habit. Scarlet-Scarlet and the glitter of the diamond crystals are transparent and very brilliant, but on exposure to light they soon become dull black and opaque. The Scarlet streak, hardness of 2.5 and specific gravity 5.57.

Proustite occurs in hydrothermal deposits as a phase in the oxidized and supergene zones. It is associated with other silver minerals and sulfides such as native silver, native arsenic, xanthoconite, stefanita, acentic, tetrahedrite and chloramphenicol.

Magnificent groups of large crystals have been found at Chañarcillo in Chile and other settlements, which gave wonderful examples of Freiberg and Marienberg in Saxony, Joachimsthal in Bohemia and Sainte-Marie-AUX-mines in Alsace.
