After a professional career alongside the best French and foreign crystal workers, Valéry Klein obtained his Companion 's certificate. In 1980, he founded the crystal factory "L'Artisan du Cristal" in the commune of Baccarat to perpetuate the tradition of working with this noble and fascinating material.

The crystal factory evolved and developed. It settled in Vallauris on the Côte d'Azur, a French town with an excellent artisanal and artistic tradition. Artistic creations, rare objects, or master pieces, all produced with the aim of ultimate perfection. Today, Artisan du Cristal pieces are sold all over the world.
