Some people are lucky and find during a walk mineral treasures. At low tide, in all seasons, we see these treasure seekers searching for fossils and marcasites.
These pebbles, of exceptional quality, are exported to more than 90 countries.

Their physic-chemical quality concerns very varied purposes such as roads, buildings, but also sanitary ware, cosmetics and dental prostheses.
