Before bringing it to life under the fingers of the designer, your jewel evolves in 3D shapes.
You can bring any changing you wish and so, take fully part in the creation of your jewel.
On your request, we can email you photos from the different steps of the making, enabling you to follow up and better understand that fantastic journey !
