Hauerite
A variety of Pyrite Group
What is Hauerite?
Being a relatively rare mineral, hauerite is highly prized by collectors. This mineral is found in low-temperature environments such as solfataras, fumaroles, and marine and clay salt deposit rich in sulfur. The presence of this brownish-gray mineral is, in fact, used as an indicator of sulfur deposits in the area.
Etymology & Origins
It was discovered in Austro-Hungarian Monarchy in Kalinka (now Vígľašská Huta-Kalinka village) sulfur deposit near Detva in what is now Slovakia in 1846 and named after the Austrian geologists, Joseph Ritter von Hauer (1778–1863) and Franz Ritter von Hauer (1822–1899).
Market Value Factors
Pricing varies for every rock and mineral, so use these universal factors to gauge Hauerite before comparing listings or appraisals.
Size & Weight
Larger, intact specimens usually command higher prices.
Rarity & Demand
Scarce material or popular varieties sell at a premium.
Condition & Finish
Chips, repairs, and heavy wear lower value; clean prep helps.
Treatment & Provenance
Untreated specimens with documented locality are prized.

Key Characteristics
Characteristics of Hauerite
Under high pressure conditions (P>11 GPa), Hauerite undergoes a large collapse in unit cell volume (22 %) driven by a spin-state transition.
Formation of Hauerite
It occurs in low temperature, sulfur rich environments associated with solfataras and salt deposits in association with native sulfur, realgar, gypsum and calcite.
