S is for sterling silver
If sterling silver jewellery is not worn for a long time, the silver may become slightly blackish and discoloured due to its reaction to the surface environment. This is not a quality defect, but an ordinary chemical reaction that occurs when the alloy meets water, air and materials containing saline or sulphur (e.g. rubber and paper).
This can be counteracted by:
1. Using the most airtight storage to minimise oxidation. Aluminium foil and pouches also help.
2. Protecting jewellery from salt water, shampoos and aggressive materials such as cleaning agents.
3. Wearing jewellery regularly to counteract oxidation.
Jewellery can be easily cleaned in a silver dipping bath or with a special silver cleaning cloth. Care should be taken when cleaning jewellery that also uses delicate materials, e.g. pearls. These materials may be attacked in the silver bath, so these should be polished with a silver cleaning cloth only.
Tip: Have your pieces professionally cleaned free of charge in our THOMAS SABO shops.
