Rivsalt UK - Persian Blue Rock Salt Refill

Persian blue rock salt is the rarest and most exclusive salt and is extracted from a salt mine in northern Iran.

The intriguing blue color 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 creating an optical illusion that makes the salt appear more or less shimmering blue.
