Algodonite is a rare mineral found in copper and silver deposits. It owes its name to its site of discovery : the Algodones mine (Chile). It is generally massive, sometimes with a botryoidal or reniform appearance ; it is extremely rare in developed crystals and always very small in size. Agodonite has a strong metallic luster and a silvery-white to steel-gray color that tarnishes quickly in air to iridescent brown-black masses that stain fingers. Algodonite concentrates arsenic from copper deposits (polymetallic veins, "red-bed" type deposits, clusters in basic lavas), in which it associates with domeykite, its most faithful companion, cuprite, native copper and frequently native silver. Locally it is an accessory ore of copper, it is sometimes cut into cabochons.
