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.

Hawaiian black lava salt draws on the tradition of incorporating volcanic elements into Hawaiian salt, which dates back centuries with alaea red clay. Modern black lava salt uses activated charcoal from coconut shells processed using volcanic heat sources on Hawaii's Big Island. The product was developed in the late 20th century as demand grew for visually distinctive finishing salts. The charcoal activation process creates an extremely porous carbon structure with high adsorptive capacity.
Best for: Dramatic food presentation, Sushi, Eggs, Grilled fish, Cheese plates.
