Caring for silver jewellery 

Although silver is a precious material, it is still sensitive to environmental influences. Over time your silver jewellery may become dull or tarnished. This can be caused by contact with perfume, soap or the acidity of your skin. To care for your silver: 

• Don't shower, bath or swim with the silver jewellery on
• Apply perfume, make-up and lotions first before putting on the jewellery 
• It’s best to remove your jewellery at night before bed and put it away in a jewellery box or pouch
• Tarnishing is a natural property of silver but is easily remedied by an occasional polish with a silver cloth.
