The theater, a historical building, is one of the emblematic places of the event. In this prestigious setting, 21 internationally renowned traders occupy the ground floor for selling beautiful and often very rare minerals.
The theater is also a privileged meeting place: either at the bar, on the terrace or on the exterior steps you will enjoy a welcoming atmosphere, encouraging encounters and exchange.
In 1962, the theater was already a mineral exchange place. Today, it is a trading place where the big names of the sector come to propose their most beautiful pieces.
