About Syngenite
Hydrated potassium calcium sulfate, typically colorless or white. It's associated with clarity and purification.
Primary Hues
Colorless, White, Yellowish, Reddish, forms prismatic or tabular crystals
Geological & Scientific Details
Syngenite is classified as a sulfate mineral mineral which typically crystallizes in the monoclinic system. Its chemical formula is K2Ca(SO4)2·H2O. Common crystal habits include tabular to prismatic crystals, lamellar aggregates and crystalline crusts.
