heart IMA grandfathered

Butlerite is a rare sulfate mineral with the chemical formula Fe^3⁺(SO4)(OH)·2H2O, consisting of iron in the +3 oxidation state, sulfate, hydroxide, and water molecules. It belongs to the orthorhombic crystal system and is classified under the Strunz classification as 7.DC.10. Butlerite typically exhibits a vitreous to pearly luster, a pale yellow to brownish color, and a relatively low hardness of approximately 3.5 to 4 on the Mohs scale. Its density is moderate, and it is generally found in association with other hydrous iron sulfates. As a sulfate mineral, it is of interest in mineralogical studies due to its unique composition and formation conditions.
