We have, at Dalloz Joaillerie, developed a quality control department that guarantees conformity of every piece all over the production process, and we are on the way to obtain ISO 9001 certification. Our collaborators are trained internally on a permanent manner, in order to maintain the same requirement level. We employ expert jewellers, expert polishers, expert setters and gluers indeed, who dispense their competences and give support on every 4 production sites.
