This specimen consists of dozens of minute crystals of proustite scattered throughout the matrix with flecks of native silver. This association is not surprising, considering that proustite is a silver arsenic sulfide. The crystals on this specimen are too small to study, even with a loupe. Proustite is named for the French chemist, J. Proust.
