The ideal chemical formula of baricite is (Mg,Fe²⁺)₃(PO₄)₂·8H₂O. It crystallizes in the monoclinic system and most commonly appears in the form of large crystals, tabular on the side pinacoid. It is colorless to light blue, with the intensity of the blue color depending on the degree of iron oxidation. Its streak is white to light blue, turning blue after a few days. The luster is vitreous to pearly on fresh surfaces parallel to the side pinacoid. It has perfect cleavage on the side pinacoid and cleaves into thin, flexible sheets. The relative hardness of barićit is low, between 1.12 - 2, and its density is 2,42 g/cm³.
