Kogarkoite is a rare sodium sulfate fluoride mineral, sometimes found as pale-blue grains or aggregates. First recognized by Russian geochemist Liya Nikolaevna Kogarko in material from Russia’s Lovozero massif and reported in 1961 as “chlorine-free schairerite,” it was formally described as kogarkoite in 1973 and named in her honor. Known locations include Russia’s Kola Peninsula, Colorado’s Hortense Hot Spring, Mont Saint-Hilaire in Quebec, Lake Magadi in Kenya, and Lake Natron in Tanzania.

Care and handling

Kogarkoite is a fairly soft mineral that can be sensitive to water, so keep it dry and never soak or rinse it. Wipe it with a dry soft cloth, handle it gently, and store it in a padded, closed container away from humidity, heat and rough contact. Wash your hands after handling it, and keep it away from children and pets.

Individual experiences with Kogarkoite vary and are personal. Treat it as the rare, quiet treasure it is, and let it teach you what it can in its own soft way.
