Proustite from Uchucchacua Mine, Peru
from the Uchucchacua Mine occupies a special place among modern “ruby silver” specimens: it is not usually the biggest proustite in the world, but the best pieces have a unmistakable Uchucchacua look—steel-gray to mirror-bright trigonal crystals that suddenly flash cherry- to blood-red when a strong light enters the crystal. That contrast is the appeal. In normal cabinet lighting the crystals may look metallic, almost blackened silver; under backlighting they reveal the saturated internal red that makes proustite one of the great optical pleasures of silver mineral collecting.
