Unlike sea salt which is extracted from salt ponds, Persian blue salt is a salt fossile or gem, whose crystals were formed 100 million years ago in the precambrian seas. This sapphire blue salt formed as inland seas and lakes evaporated. This Persian blue salt existed a hundred million years ago along with species which disappeared at the time of the extinction of the dinosaurs at the end of the Cretaceous period due to an asteroid, a volcanic eruption or the retreat of the oceans: large marine and flying reptiles, the ammonites (ancestors of the nautilus) and dinosaurs.
The blue colour of this Iranian salt comes from sylvinite, a potassium mineral, only present in the halite salts. They are normally pink and the blue colour is extremely rare. Persian blue salt is extracted from the mountains of the Semnan province in Northern Iran and more specifically in the Ergourz mountain range.
Persian blue salt is rich in nutritients. The mineral extracted from the Iranian mountains is rich in calcium, magnesium, iron and potassium. As only a few tons are extracted per year, it’s one of the world’s rarest salts.
The package contains the appropriate salt grater.
