All our Medeore jewelry is cast and assembled in our workshop in Perpignan, so we specify that when you order a Medeore piece of jewelry you are purchasing care before purchasing a piece of jewelry. The jewel is only the receptacle of the programmed care which allows you to measure the evolution of the care in the material. In order to precisely measure its evolution, we advise you not to wear your jewelry when it can be altered or torn off or during sporting activities.
