The Restoration Service allows an extremely damaged piece of Cartier jewelry to rediscover its aesthetic attractiveness and original appearance.
Performed by a Cartier specialist jeweler, the Restoration Service includes the following operations:
- the diagnosis;
- the preparation of an estimate.
After the estimate has been accepted:
- the restoration process is carried out in a succession of stages:
- soldering: this involves fitting together two parts of a piece of jewelry with a piece of metal that has been heated to a very high temperature using a blowtorch; the jewel is then immersed in an acid bath so as to remove any trace of oxidation.
- reshaping: the piece of jewelry's original shape is restored using a boxwood mallet.
- the setting of the stones: this extremely delicate stage sometimes involves rebuilding the prongs and the mounting so as to create a secure setting.
- polishing, using brushes saturated with three different abrasive pastes, until a dazzling surface is obtained;
- the cleaning of the piece of jewelry, particularly its less accessible parts, by immersion in an ultrasonic tank filled with lukewarm soapy water. All jewelry creations may be subjected to ultrasound treatment, except for those containing emeralds, pearls and certain other gems that are considered too delicate.
- rhodium plating: to reinforce the whiteness and brilliance of white gold, it is sometimes covered with a fine layer of rhodium, a rare precious metal of the platinum family.
This operation consists of the following stages:
- before polishing, the remaining layer of rhodium is removed so as to obtain a naked surface to which the new layer can be applied;
- after polishing, the immersion of the piece of jewelry in a rhodium bath to deposit a new fine layer of metal on the surface of the white gold.
- a technical and aesthetic inspection is carried out in accordance with Cartier quality criteria.
Please note that during the polishing process a fine layer of metal is removed. This is why we recommend you not to have this service carried out more than twice in the lifetime of a piece of jewelry made of white or yellow gold. It should also be noted that certain deep scratches cannot be removed. Please also note that it is technically impossible to polish white gold so as to give it a black finish.
