About Melanterite
Hydrated iron sulfate, forming green to bluish-green crystals that dehydrate to white powder; water-soluble. It's associated with energetic cleansing and vitality, but mainly a collector's mineral due to instability.
Primary Hues
Green, Bluish-Green, White, Yellowish (dehydrates to white powder), (Water-soluble, handle with care)
Geological & Scientific Details
Melanterite is classified as a sulfate mineral mineral which typically crystallizes in the monoclinic system. Its chemical formula is FeSO4·7H2O. Common crystal habits include encrustations and capillary efflorescences; rarely as equant pseudo-octahedral, prismatic or tabular crystals.
