Fairfieldite is a phosphate mineral with the chemical formula Ca2Mn2+ (PO4)2 · 2H2O. It crystallizes as light-colored, often prismatic crystals with a vitreous to resinous luster and forms a relatively soft mineral in the monoclinic system. Specimens are commonly found as small, tabular crystals that can occur in compact aggregates, sometimes displaying a pale yellow to colorless appearance.

About Fairfieldite
Notable specimens have been reported from localities in the United States, where Fairfieldite is among the rarer phosphate minerals seen by collectors. The rarity and specific paragenesis contribute to its appeal, as it showcases distinctive calcium and manganese-rich phosphate chemistry that contrasts with more common phosphate species. Collectors value Fairfieldite for its delicate habit and its role in representing the diversity of phosphate minerals found in pegmatitic and hydrothermal environments.
