Know How

The GROSPIRON Company has been renowned for its stone cutting craftsmanship since its founding, and possesses the largest stone cutting workshop in France.

Two workshops, one in Paris, the other in the high Jura plateau, house 15 highly qualified stonecutters, amongst a larger team of 36 employees. Three of the stonecutters have been awarded “Meilleur Ouvrier de France”.

Our traditional approach to apprenticeship allows the maintenance and transmission of the deep craftsmanship intrinsic to the precision cutting of colored stones, both precious and semi precious.

We propose lapidary fitting of stones, placement on preexisting jewelry pieces, or on drawing (including watch boxes) and we are also specialized in recutting for invisible setting.

Our technique, which allows the stones to be shaped and cut so that they “fit” onto each other, permits all metallic support to disappear: it’s a hand-made cut that demands an exceptional craftsmanship.

GROSPIRON works on request for all major brands of French jewelry and Swiss watch makers, and has also participated in the manufacturing of some of the finest pieces of high-end jewelry in recent years.

GROSPIRON’s clients can be guaranteed of the entire protection of their exclusive models and a precision in work down to 2/100 mm, after an intransigent selection of the colored stones.

A wide stock of calibrated stones allows us to respond to most orders with very short notice.
