Blue Halite: Same Chemistry as Table Salt, One of the Rarest Colours in Nature

by Laura Konst

Blue Halite is a rare colour variety of Halite Sodium Chloride formed within ancient evaporite deposits. Its distinctive blue colour is caused by radiation induced structural changes within the crystal lattice rather than chemical impurities. This guide explores the mineralogical properties geological formation and care considerations that make Blue Halite a unique and fragile collector mineral.

Pink Halite: It's Salt, But Not the Kind for Your Kitchen

by Laura Konst

Pink Halite is sodium chloride — the same compound as table salt — but the specimen on your shelf is not the same as the pink salt in your kitchen. Where Himalayan salt gets its colour from iron oxides, Pink Halite is coloured by ancient halophilic microorganisms trapped within the crystal as it formed. This guide explores the biology, geology, and surprisingly complex science behind one of the most distinctive and fragile minerals in any collection.
