Erythrite

（重定向自Red cobalt）

Erythrite or red cobalt is a secondary hydrated cobalt arsenate mineral with the formula (Co₃(AsO₄)₂·8H₂O). Erythrite and annabergite (Ni₃(AsO₄)₂·8H₂O) (nickel arsenate) form a complete series with the general formula (Co,Ni)₃(AsO₄)₂·8H₂O.

Erythrite crystallizes in the monoclinic system and forms prismatic crystals. The color is crimson to pink and occurs as a secondary coating known as cobalt bloom on cobalt arsenide minerals. Well-formed crystals are rare, with most of the mineral manifesting in crusts or small reniform aggregates.
