English French THE COMPANY TRADING SAVOIR-FAIRE GROSPIRON GUIDE CONTACT The story behind our company In 1931, at the age of 23, René GROSPIRON set up the Company rue Portefoin, in Paris’ 3rd arrondissement. Through his father in law, he belonged to a family of traditional stonecutters from Lélex, a village in the Valserine valley, and a hamlet called Les Moussières, located about twenty kilometers from Saint-Claude. His younger brother Jean, a synthetic stone lapidary, preferred to stay in the Jura. Years later, he would be the proud grandfather of Edgar GROSPIRON – the famous Olympic ski medalist. In spite of the difficulties of the Great Depression of the 1930s, the trade in semi precious and synthetic stones developed rapidly, and after several changes of location in Paris’ Marais district, René GROSPIRON finally settled down in 1946 at 34 rue Drouot in the 9th arrondissement. Founded in April 1945, LA PIERRE DU JURA (SARL) became a public limited company in 1954. The official name of the company would change as well in March of 1958, becoming GROSPIRON and Co. (SA), and at last GROSPIRON Establishments (SA) in 1968. The company adopted the SAS statute (simplified joint stock company) in February of 2001. Lire plus Home - Contact
