Most important exhibitions Sainte-Marie-Aux-Mines

Like every year during the last week of June, Sainte-Marie-aux-Mines unveils a thousand and one wonders from the bowels of the earth, treasures as mysterious as they are fascinating. We discover minerals from the ends of the earth and precious stones whose purity and rarity can reach new heights. Mineral & Gem raises Sainte-Marie-aux-Mines to the^2nd place in the world, with a thousand exhibitors from about fifty countries. Professionals and amateurs alike can admire and acquire minerals, fossils and fine stones.
