The purity of gold is measured in carats. 24ct is pure gold; any carat below this is a gold alloy, a mix of gold and other metals.
The colour of gold – yellow gold, white gold or rose gold – is achieved through the mix of metals in the alloy. By definition, it isn’t possible to find 24ct white or rose gold.
As an alloy with the lowest gold to metal ratio (9 parts gold, 15 parts metal), 9ct gold makes the most durable gold jewellery, suitable for daily wear and most resistant to scratching.
Chlorinated water (from swimming pools or hot-tubs) and household cleaning products can all damage your gold jewellery.
CARING FOR YOUR GOLD JEWELLERY
Gold jewellery can be restored to its former shine by polishing with a soft, lint-free cloth.
