Poitevinite
Poitevinite is a hydrated copper iron sulfate mineral with the chemical formula (Cu,Fe)SO4 * H2O. It belongs to the triclinic crystal system and is classified under the Strunz system as 7.CB.05. This mineral is typically found in arid environments where evaporation processes occur. It exhibits a vitreous luster and can display a range of colors from green to blue. With a relatively low hardness and a moderate density, poitevinite is a secondary mineral that forms through the alteration of primary sulfide minerals. Its classification as a sulfate mineral reflects its chemical composition and structural characteristics.
Overview
Poitevinite is a hydrated copper iron sulfate mineral with the chemical formula (Cu,Fe)SO4 * H2O. It belongs to the triclinic crystal system and is classified under the Strunz system as 7.CB.05. This mineral is typically found in arid environments where evaporation processes occur. It exhibits a vitreous luster and can display a range of colors from green to blue. With a relatively low hardness and a moderate density, poitevinite is a secondary mineral that forms through the alteration of primary sulfide minerals. Its classification as a sulfate mineral reflects its chemical composition and structural characteristics.
Etymology
Poitevinite is named after Théophile Eugène Poitevin, a French chemist and mineralogist. The mineral was approved by the International Mineralogical Association (IMA), but no specific discovery year is provided in the facts.
How to recognize it
Poitevinite can be identified by its vitreous luster and characteristic green to blue coloration. It has a relatively low hardness on the Mohs scale, though the exact value is not provided. A streak test may reveal a pale color, and its density is moderate. Due to its similar appearance to other sulfate minerals, it can be confused with species like chalcanthite or brochantite, but its triclinic crystal system and chemical composition help in differentiation.
Trivia
Poitevinite is notable for its unique chemical composition, which includes both copper and iron in its sulfate structure. Its triclinic crystal system is less common among sulfate minerals, making it an interesting subject for mineralogical study. Additionally, the mineral is named after a notable 19th-century scientist, Théophile Eugène Poitevin, which adds to its historical significance in mineralogy.
Indicative prices
Poitevinite is a rare mineral and is not commonly traded as a gemstone or in jewelry. Indicative prices for mineral specimens may vary by source and depend on origin, size, and aesthetic appeal. High-quality, well-formed crystals or specimens from notable localities may be valued in the hundreds to low thousands of USD or EUR. Jewelry or cabochons, if available, are extremely rare and prices would be highly variable.
