Before putting on your piece of jewelry, examine it for a moment:
- check that the clasp (and its safety catch if it has one) is not "loose":
check that the settings of the stones have not moved, as follows:
- either by shaking the piece of jewelry close to your ear: if you hear a slight noise, this means that the stones are no longer perfectly secured;
- or by rubbing the piece of jewelry against a thin cloth: if the cloth catches, this means that the prongs have moved.
If you are in the slightest doubt, it is advisable not to wear your piece of jewelry until you have had it checked at a Cartier boutique.
