Product description+
Organic Coarse Celtic Sea Salt from Guérande
Our Organic Coarse Celtic Sea Salt, traditionally known as Sel de Guérande or Celtic grey sea salt, is harvested from the coastal salt marshes of Guérande on the Atlantic coast of France.
Seawater is naturally evaporated by the sun and wind before the salt is carefully collected using traditional harvesting methods. It is left unrefined and free from additives, preserving its naturally grey appearance, characteristic moisture and robust coarse texture.
Crystal Health & Beauty packs this traditional French sea salt into a convenient 500g resealable bag. Shop Celtic sea salt UK from our Daily Essentials range.
Why Choose Our Celtic Sea Salt?

- Nothing added: Free from added anti-caking agents, preservatives and bleaching agents.

Why Is Celtic Sea Salt Grey?
The salt’s characteristic grey colour comes from its contact with the clay-lined salt ponds in which it forms. Its appearance and slight natural moisture are normal features of traditional Sel de Guérande.
Because this is a naturally moist, unrefined salt, the crystals may occasionally clump together. This is completely normal and does not affect the quality or usability of the product.
