General Care

A professional should regularly check jewellery for damage or wear. If you have any concerns about your jewellery condition, take it to your local member of the NAJ. They will take great pride in helping you keep yours looking as good as the day it was bought. Here are a few tips on some of the things you can do to keep it in great shape:

  • Take your jewellery off if you're involved in any activity which could scratch, knock or damage it. If in any doubt, take it off and keep it safe.
  • Take it off when you go to bed.
  • Keep it well away from chemicals, especially chlorine. If it does come into contact with chemicals, rinse it in water immediately.
  • Bathe and apply any lotions or perfumes before you put your jewellery on. Organic gemstones like pearls and opals are particularly vulnerable to acids, even perspiration.
  • Store it separately, ideally in a soft-lined box or case, so that your favourite pieces don't tangle, rub or scratch one another. Pearls in particular should be kept separately as they are easily scratched by hard gemstones.
  • Make sure chains and necklaces are fastened when storing to avoid tangling.
  • Remove jewellery while cooking and cleaning.Keep it well away from chemicals, especially chlorine. If it does come into contact with chemicals, rinse it in water immediately.
  • When storing jewellery, please keep it away from sunlight, excessive heat or damp conditions.

Gemstone Cleaning

Gemstones are bought for their sparkle and colour, so it's essential to keep them looking their best. However, it is important to know what type of gem you are cleaning and how to get it back to looking like new.
Many coloured gemstones have been treated to enhance their appearance. These treatments can negatively interact with some cleaning products and damage the jewellery. If in any doubt, take your jewellery to a jeweller for advice.
Although a gemstone may appear tough, many can be susceptible to heat. Whenever cleaning, make sure that you use warm water rather than hot or boiling water. Inclusions within gemstones can weaken their structure if aggressively cleaned. Gemstones, such as emeralds that have been oiled to improve colour, can be negatively affected by mechanical cleaning such as steam and ultrasonic cleaning.Gemstones are bought for their sparkle and colour, so it's essential to keep them looking their best.

For nearly all coloured gemstones cleaning with warm water, a couple of drops of washing-up liquid and a soft brush will be more than adequate. Make sure to avoid hard and rigid brushes. A toothbrush is usually an excellent tool due to head size and flexibility. If using a toothbrush, it is important to buy one labelled with a soft or extra-soft brush.
When cleaning malachite, use cool water as it is particularly sensitive to heat and hot water may damage the gemstone.

Diamond Cleaning

Despite being the hardest naturally occurring substance on Earth, diamonds require care and attention. They are hard, but they can still fracture and be scratched by other diamonds due to their directional hardness. Oil deposits from fingers and general dust and grime can quickly adhere to the diamond surface and affect a diamond's brilliance.
Handle the diamond carefully and store it away from other jewellery to avoid scratching the other pieces, including other diamond jewellery. Keeping the diamond in individual small plastic bags or a fabric-lined case will help reduce damage, wear and a build-up of dirt.
Clean the diamond regularly. Soak in warm water with a degreasing solution (a couple of drops of washing-up liquid will suffice). Gently brush with a soft, clean toothbrush before drying with a lint-free cloth. Be extra careful with the stone's setting as this may be fragile. Avoid using bleaches or other hard abrasives. This can easily damage the precious metal in which the diamond is mounted.When cleaning malachite, use cool water as it is particularly sensitive to heat and hot water may damage the gemstone.
