Physical properties
Hardness of 6 to 6.5 on the Mohs scale, brass-yellow color, metallic luster, and isometric crystal system forming distinct cubes.
Formation & geological history
Forms in hydrothermal veins, sedimentary rocks, and metamorphic deposits through the reaction of iron and sulfur under varying temperature conditions.
Uses & applications
Used in the production of sulfur dioxide and sulfuric acid, historical use as an ignition source, and popular in mineral collections and jewelry.
Geological facts
Commonly known as fool's gold due to its superficial resemblance to gold, though it is harder and leaves a greenish-black streak.
Field identification & locations
Identified by its brassy metallic color, cubic crystal habit, and high hardness that prevents scratching with a knife; found globally.
