The mineral Pyrite, also known as "fool's gold," is an iron sulfide celebrated for its striking metallic luster and pale brass-yellow hue, which gives it a resemblance to gold and its iconic nickname. Pyrite typically forms in cubic crystals, with rarer occurrences of cubo-octahedral and pyritohedral shapes. Some exceptional specimens with beveled edges originate from Navajún, Spain.
Since the 1980s, Pyrites from Navajún have become world-renowned for their remarkable quality and perfection. This unique locality has been a cornerstone of international mineral fairs, attracting collectors, mineralogists, and enthusiasts from across the globe. Over the years, these exceptional pyrite specimens have solidified their reputation in the international collecting market, becoming highly sought after and a symbol of Spanish mineralogy, particularly in La Rioja.
With the mines now closed, Navajún pyrite specimens have become increasingly rare and valuable, making them a prized addition to any collection.
