Neptunite is a silicate mineral characterized by the formula KNa2Li(Fe2+, Mn2+)2Ti2Si8O24. It forms a series with mangan-neptunite as manganese content increases, while watatsumiite is a variant where vanadium substitutes titanium in the composition. First identified in 1893 from the Narssârssuk pegmatite in West Greenland, neptunite is also located in natrolite veins within glaucophane schist in San Benito County (ORIGIN OF THIS SPECIMEN), California, as well as in Mont Saint-Hilaire, Quebec, and the Kola Peninsula in Russia. The mineral derives its name from Neptune, the Roman god of the sea, due to its connection with aegirine, named after Àgir, the Scandinavian sea deity.
