How to clean diamonds 

Cleaning your diamonds and diamond jewellery at home is a simple process, that you can undertake with a few items you may already have around the house. Cleaning your diamonds is an important process to keep your jewellery looking its best, as well as a good measure to ensure your jewellery isn’t becoming damaged from daily wear and tear. Follow The Diamond Store’s expert advice to keep your diamond jewellery sparkling. 

Clean diamonds with a mild detergent and a toothbrush 

Firstly, ensure you have everything necessary to clean your diamond jewellery. 

We recommend having on hand: 

  • A bowl of lukewarm soapy water (using a mild detergent, such as washing up liquid) 
  • A bowl of lukewarm water (plain) 
  • A soft toothbrush, reserved exclusively for cleaning your diamonds 
  • A soft, lint-free cleaning cloth 

How to clean diamonds at home 

Firstly, check over your jewellery for any loose stones, or any prongs that look like they may have been damaged. Introducing water to damaged jewellery may cause further problems, so if you think there’s a problem with your piece, hold off on cleaning, and take to a professional jewellery for further inspection. 

However, once you’ve assessed your diamond jewellery and are sure it is in good condition to clean, follow the below steps. 

  • Place your diamonds or diamond jewellery in the bowl of lukewarm water containing the detergent and leave to soak for around ten minutes. The degreasing agent will help to remove the build-up of grime and dirt. 
  • After ten minutes have passed, remove your jewellery, and place it in the bowl of plain lukewarm water, for a further ten minutes. 
  • Once your jewellery has soaked, remove it from the water, and buff over the diamonds with a soft toothbrush (like those made for children). Ensure you get into all the nooks and crannies but use a light touch – vigorously scrubbing could damage the prongs holding your stones, or scratch gold pieces. 
  • Then, simply dry your piece with a clean, lint-free cloth. If intending to store after cleaning, leave to air on a towel until bone-dry. 

Care tips to keep your diamonds in top condition

  • Don’t use harmful chemicals on diamond jewellery 

Diamonds are very resilient – but harmful chemicals and cleaning products can still damage your diamond jewellery. Certain chemicals can affect the metals your diamonds are set in and could – for example – make the prongs loose, leading eventually to you losing your jewel altogether. So, unless recommended by a professional jeweller, always use mild detergents, shampoos and dish soaps on your diamond pieces. 

  • Clean diamond jewellery regularly  

Our experts recommend that, in an ideal world, jewellery worn daily would be cleaned once a week. However, we know that sometimes these things can slip our priorities list – so just ensure you give them a clean whenever you notice your diamonds are looking a little lacklustre.  

  • Take your diamond pieces to a jewellery for yearly maintenance 

A yearly maintenance check to ensure everything is in working order for your most precious pieces is always a good idea. A professional jeweller can spot faults and problems and can – in some cases – stop the damage happening before it does.  

  • Store diamonds with other diamonds 

Diamonds are the hardest of all the gems, which means they can actually scratch other, softer, gems, as well as metals. Ensure you store all your diamond pieces together, and separately from other gems. Ideally, no pieces would be touching each other inside your jewellery box.

  • Treat your diamonds as ‘jewels, not tools’ 

When jewellery can be worn every day, we tend to take this literally – and sometimes forget to ever remove it! It’s important to remember that when doing normal daily activities, your jewellery will bear the brunt. Ensure that at least when you do any sort of high impact activity that could damage your jewellery (such as gym classes) or when using chemicals that could degrade it (such as when using bleach and other harsh chemicals to clean) you remove your treasures, to keep them safe. Want to read our tips for wearing diamond jewellery?
