This salt is probably one of the most unusual salts on the market today. Its colour is not caused by a specific mineral. It’s extracted from a salt mine in the northern province of Semman in Iran.

The intriguing blue colour occurs during the forming of the salt’s crystalline structure, as intense pressure is exerted on the salt deposits. The individual crystals fracture the light in an unusual way and the resulting blue (which is caused by an optical illusion), becomes visible.

This same blue effect can be seen in compressed glacier ice. Its flavour is described as an initial bold taste, but quickly becomes mild and pleasant.
