Graftonite-(Mn)
Graftonite-(Mn) is a rare phosphate mineral with the chemical formula manganese iron(II) diphosphate. It belongs to the monoclinic crystal system and is part of the phosphate mineral class. This mineral is typically characterized by its dull luster and earthy appearance. Its color is generally brownish or reddish, and it has a relatively low hardness on the Mohs scale. Graftonite-(Mn) is not commonly found in nature and is of interest primarily to mineral collectors and researchers due to its unique chemical composition and classification within the phosphate group.

How to recognize it
Graftonite-(Mn) can be identified by its earthy luster and reddish to brownish color. It has a low hardness on the Mohs scale, though the exact value is not specified. The mineral does not exhibit a distinct streak or notable density for practical identification. Due to its rarity and lack of distinguishing physical properties, it is often confused with other phosphate minerals. Careful chemical analysis is typically required for accurate identification.
