Langbanite is a very rare complex silicate, and this superb, old-time specimen is from the famous Langban, Sweden, the Type Locality. There are two excellent, euhedral crystals set in a calcareous schist that is highly fluorescent. These two elongated, prismatic crystals are 1.2 cm long, which is simply amazing for the species.
