Thierry Courtadon sculpts a gray lava stone specific to Auvergne and its chain of puys. He comes from a family of stonecutters but he is the first in his lineage to make Volvic stone artistic, malleable and luminous. This unique, charismatic sculptor combines the life of an artisan and the life of an artist. While becoming one with nature, through his creations, he gives this heritage stone its letters of nobility.
