Pyrite with Quartz and Galena

Huanzala Mine, Huallanca District, Dos de Mayo Province, Huanuco Department, Peru

Overall size 31.0 x 16.5 x 13.0 cm. Deep grey semi-lustrous galena and highly lustrous striated cubic pyrite of rich golden hue overgrown with elongated quartz points with subtle frosted translucency. From the Huanzala mine, a prolific producer of fine pyrites and fluorite.

Iron Sulfide (FeS2), well known as the infamous “fool’s gold” and a prime commercial source of both sulfur and iron, is highly coveted by collectors intrigued by the lustrous, cubic and complex modified crystals that form both alone and in association with other minerals in rare conditions. Notable discoveries include Navajun, Spain and the Huanzala deposit in Peru, both very well represented in this collection.
