To preserve their brilliance, special care must be given to each type of gemstone based on their mineral properties.
We recommend that you bring in your fine jewelry every year to a CHANEL boutique. It will be carefully taken care of by our expert jewelers.
Advice for each type of stone or precious material is further detailed in below.
PRECIOUS METALS
Gold
To avoid scratches, keep your gold jewelry from rubbing against other set pieces of jewelry. Polishing and rhodium plating can restore white gold to a like-new condition, removing any signs of wear and tear. Do not hesitate to come into a CHANEL boutique to request these services. Clean your gold jewelry with warm water and a soft brush before drying it with a soft cloth.
Platinum
To avoid scratches, keep your platinum jewelry from rubbing against other set pieces of jewelry. Clean your platinum jewelry with warm water and a soft brush before drying it with a soft cloth.
CERAMIC
As a non-oxidizing material, ceramic is hard to scratch. However, deposits of materials giving the appearance of scratches can form upon contact with other pieces softer than ceramic, such as gold or titanium. A simple cleaning in our workshops can remove these marks. Clean your ceramic jewelry with warm water and a soft brush before drying it with a soft cloth.
PEARLS
Pearl is an organic material which needs to be worn regularly and is very sensitive to chemical substances. In order to preserve its brilliance, avoid putting it in contact with cosmetics that could alter the shine (perfumes, creams, etc.). Store your pearl jewelry in its original case, away from other pieces of jewelry and covered with a soft cloth in a humid place.
To humidify the air, you can also put a small glass of water close to your piece of jewelry.
Clean with a damp soft cloth.
PRECIOUS STONES
DIAMOND
A diamond can only be scratched by another diamond, but it can easily scratch every other metal or stone with which it comes into contact. In order to avoid scratching, it is recommended not to wear multiple pieces of jewelry on the same finger or wrist. Despite its hardness, the diamond remains a delicate stone, likely to break in the event of a strong impact.
Clean your diamond with warm water and a soft brush before drying it with a soft cloth.
EMERALD
Since it is particularly sensitive to temperature changes, avoid exposing your emerald to thermal shocks or extreme heat sources.
Emerald is a delicate stone. It requires particular care, only available through our expert jewelers. We therefore recommend that you visit a CHANEL boutique for any maintenance of your emerald-set jewelry.
