Native tungsten is the mineral form of the metal tungsten, with the accepted name simply tungsten. In its pure metallic form, natural tungsten is very rarely encountered and quite exotic. Nanocrystals no bigger than 2 μm of native tungsten were identified in the lunar soil at the Luna 24 landing site Mare Crisium.
