What is Picromerite?
Picromerite (synonyms: schoenite, schönite) is a mineral from the class of hydrous sulfates lacking additional anions, and containing medium to large cations according to the Nickel–Strunz classification.
Market Value Factors
Pricing varies for every rock and mineral, so use these universal factors to gauge Picromerite 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 Picromerite
Picromerite dehydrates in dry air, and crystals then show dull, spherical dehydration zones. Progressive dehydration leads to leonite.
Formation of Picromerite
Picromerite is found on comparatively few places, currently (2015) only about 40 localities are known. It was first identified in active volcanic fumaroles on Mount Vesuvius by Arcangelo Scacchi in 1855 and has also been found in volcanic deposits on Mount Etna and on Hawai'i. It is more commonly found in the kainite zones of some marine salt deposits, among them salt mines in Thuringia, Lower Saxony and Saxony-Anhalt (Germany), near Hall in Tirol, Hallstatt and Bad Ischl (Austria), near Whitby (UK), and in the Carlsbad Potash District (New Mexico), also on salt lakes in western China. Picromerite can also form in sulfate-rich hydrothermal ore deposits and is found in slag heaps of some ore and coal mines. Picromerite is often accompanied by anhydrite, epsomite, halite, hohmannite, kainite, metasideronatrite und metavoltine, depending on the locality.
