Gold is a soft, malleable metal, and so gold jewellery is often made from a combination of gold and other metals to make the material strong and robust.

18-carat gold jewellery is one of the most high-purity strains of gold jewellery, made up of 75% gold and 25% other materials (9 carat is 37.5% gold). Metals like zinc, copper, and nickel are commonly used alongside gold, with different tones creating a yellow, white, or rose gold finish.

The high concentration of gold used in 18-carat gold jewellery makes it an upmarket choice compared to jewellery made using 14ct or 9ct gold.

Pure 18-carat gold jewellery tends to be on the higher end of the price scale, making it a perfect for a special gift or shopping for something to wear to a memorable event.

It also could be a safe choice for those with sensitive skin who have allergic reactions to other metals.

While it's more durable than 22-carat or 24-carat gold, the high concentration in 18-carat gold jewellery means it's still a precious and delicate material that needs to be looked after. With a bit of care and maintenance, you can keep your gold jewellery in beautiful condition:

  • Keep it away from harsh chemicals and products - always remove jewellery before bathing, swimming, and cleaning.
  • Because gold is a soft and malleable material, it can scratch easily, so be careful when wearing rings and bracelets that may get caught on something.
  • Store your pieces in soft jewellery bags or boxes to prevent them from scratching and tangling with each other.
  • To clean your gold jewellery, use a soft brush or cloth and warm water. Allow it to dry completely before putting it away.
