Himalayan pink salt is the purest salt in the world. Rock salt is extracted by hand from the heart of the Himalayan foothills, in the mines of Khewra, a region of Pakistani Kashmir. It is of marine origin and comes from fossil deposits left by the sea. Coming from deposits that are 500 and 1000 meters deep, this salt is perfectly protected from external pollution. The pink color comes from the high iron content, which when oxidized makes the salt pink to red. Very popular with gourmets, it is also a beauty ally in cosmetics and an air purifier.
