The Museum aims to collect, classify and make known the minerals of the Aosta Valley and a number of crystals and semi-precious stones from around the world.
It currently has about 750 pieces on display, most of which come from the mountains near Saint-Vincent, in particular from Mount Barbeston, from Emarèse, from Brusson and Champorcher, all sites known to be rich in minerals.
The rarest and most beautiful pieces come from gold, iron and magnetite mines, now abandoned.
The museum also has a collection of about 170 fossils.
