The journey begins as you walk into the historical Hôtel de Mercy-Argenteau on Paris’ Grands Boulevards. In the heart of this 18th century mansion, you meet your two guides: a gemologist and an art historian. 

The ruby, stone of fire and power, will unveil its secrets along with its scientific specificities, from inclusions to fluorescence.

Please note that it is mandatory to register for the whole cycle: it is not possible to follow a session in isolation.
