Each gift box contains an anti tarnish tab which should protect your jewellery for up to six months.
The most effective way to keep your jewellery looking its best is to wear it. Wipe with a soft cloth after wearing and it will look like new at all times.
Should your silver lose a little shine it can be restored by gently polishing with a silver cleaning cloth or cleaned gently using a very soft baby's toothbrush dipped in some warm water with a drop of washing up liquid (don't use harsh chemicals). Rinse and dry carefully with a soft cloth.
I would always recommend removing jewellery before showering, bathing, swimming and applying perfumes, body creams, lotions etc. Always allow perfume to dry before putting on your pieces.
