925 Sterling Silver
Items made from 925 Sterling Silver are a combination of 92.5% pure silver and 7.5% of other metals, which is usually copper. The reason silver needs to be combined with other metals is because pure silver is too soft and flexible and will not hold its shape. A bit of hardness needs to be introduced, so that jewellers can make intricate and complex designs that can be worn on a day-to-day basis.
Why does silver jewellery turn black?
No matter what, nothing stops silver from tarnishing. When silver is exposed to the air and atmosphere, it causes a chemical reaction. This reaction creates something called silver sulphate. It is a thin build-up of sulphate lining your jewellery.
How to clean your jewellery.
The good thing is, the sulphate does not harm your jewellery, and it’s easy to get it off.
With every Zookkie order, you will receive a small Silver polishing cloth. This is made of high quality material impregnated with a silver cleaner and anti-tarnish agent. Rub the jewellery between your fingers, while within the cloth and you will obtain a brilliant polish with long lasting protection against tarnish. The small cloth remains effective as long as it is not washed.
What also should I do?
- Put your piece on after you have applied creams, sun screen or lotions.
- Take your piece off before bathing, playing in anything gunky or when sleeping.
- Wipe your piece clean with the soft polishing cloth when it starts to look dull to remove any oils from building up.
