About Persian Blue Salt
Persian blue salt is one of the rarest salts on earth. It is found only in a few salt mountains in Iran's Semnan province. The blue coloration occurs when the halite crystal lattice is compressed under extreme geological pressure over millions of years, causing a structural change called sylvinite that refracts light to appear blue. Annual production is only a few tons.
Best for: Finishing seafood, Foie gras, Truffle dishes, Desserts, Specialty cocktails.

Volcanic salts have emerged from regions where volcanism and ocean meet. In Hawaii, the tradition of incorporating volcanic elements into salt dates back centuries with alaea clay. Modern volcanic salts extend this concept with activated charcoal from volcanic coconut shells, Icelandic lava salt from geothermal brine, and Mediterranean varieties from volcanic islands like Sicily and Santorini.
Best for: Finishing grilled meats, Dramatic presentation, BBQ, Tropical dishes.
