A fantastic journey in the heart of the gems

We offer you a fantastic journey in the heart of the gems.

Floating in the air, who has never dreamed of it. Here is a poetic world, that of gems, where you can discover a universe close to the cosmos, silent and luminous. In a confined space that might seem insignificant, flickering signs scatter light and geometric shapes for those who take the time to look at them.

So, equipped with a magnifying glass or a microscope, we can escape. We marvel at the beauty of gems. Esprit Joaillerie invites Marine Bouvier, a professor of gemology at the AGAT, to guide us through this fantastic universe by sharing her stunning photos of inclusions.
