Avoid keeping your jewellery next to a strong heat source or in direct sunlight as this can cause fading over time.
From time to time, you can rub the jewellery with a soft cloth to restore the original lustre and keep the piece in the best possible condition. For the wooden part of the pendant, apply cooking oil with a soft cloth once in 3 months. The surface can get scratches from extreme abuse.
To care for sterling silver chains:
Warm water and a soft cloth are the best ways to maintain the beauty of your jewellery. For a thorough, occasional cleaning, a drop of soap is all that is needed to restore the lustre. Many chemicals offered for cleaning jewellery tend to be abrasive and caustic and can damage your jewellery or change its colour. After cleaning, make sure you have dried your jewellery well with a clean and dry soft cloth. Salt water and chlorine in swimming pools will attack all jewellery.
