crown IMA grandfathered

Haidingerite is a calcium arsenate hydroxide mineral with the chemical formula Ca(AsO3OH)·H2O. It belongs to the orthorhombic crystal system and is classified under the Strunz system as 8.CJ.20. This mineral typically exhibits a vitreous luster, a white to pale yellow color, and a hardness of approximately 3.5 to 4 on the Mohs scale. Its density is relatively low, ranging from 2.8 to 3.0 g/cm³. Haidingerite is a member of the nesosilicate group, though it is not a silicate but rather an arsenate, which is chemically analogous to silicates.
