Tarnishing is a natural process that is caused when sterling silver is exposed to humidity and chemicals such as hydrogen sulphide in the air. To minimise the speed of this process we advise you to do the following:Remove jewellery when bathing, showering or swimming as water and chemicals (especially chlorine) can affect the longevity of the gold plating or encourage silver to tarnish.Chemicals in make-up, hair spray, scent and moisturisers can also affect the beauty and shine of your jewellery, so apply these before wearing your jewellery.Remove jewellery when doing household tasks such as cleaning, playing sport or other strenuous activities since jewellery may become scratched or harmed by sharp blows.Do not wear your jewellery whilst on the beach or sunbathing since extreme temperatures and strong UV rays can cause gemstones to fade in colour and lose their original beauty, whilst sand can damage their surface.CLEANING SILVER JEWELLERY.At Cara Tonkin we use an oxidised finish on many of or silver pieces. If you piece is partially oxidised we advise cleaning the bright silver areas by rubbing with a silver polishing cloth. Jewellery that is comprised of just silver without an oxidised finish can also be dipped in silver dip. This is an effective and easy method of getting a bright finish back on your jewellery.
