Diamonds are undeniably one of the most beautiful gemstones on earth, and will often be part of the most expensive pieces of jewellery youown. That’s why it's so important to look after your diamonds and keep them looking their dazzling best. In this guide, we explain how to clean and care for your diamond jewellery, whether it’s that all-important engagement ring or a treasured tennis bracelet. 

Cleaning your diamond step-by-step: 

The most magical thing about a diamond is its sparkle. That’s why it’s important to maintain it as much as possible. Wearing a diamond daily, in an engagement ring, for example, means it will require special care to help it stand the test of time. Dirt can build up easily from everyday activities, so if your diamond is looking a little duller than usual, it could be time to give it a much-needed clean. It’s important to remove dirt so that it does not build up and damage your diamond, and restoring it will enable it to transmit light as beautifully as it can. Here’s how to clean your diamond pieces. 

Step 1: Bathe your diamond in lukewarm water and washing up liquid for 10 minutes to allow dirt to break down, making it easier to remove. 

Step 2: Leave your diamond in the soapy water for approximately ten minutes. This gives enough time for any built up grime to break down allowing for easy removal of dirt.

Step 3: Prepare a cup of glass cleaner, making sure it’s ammonia-based and not chlorine-based so not to react with your diamond or precious metal.   

Step 4: After 10 minutes of soaking, place your diamond in the cup of glass cleaner. 

Step 5: With a toothbrush or soft bristle brush, gently clean the diamond, focusing on the edges and back. 

Step 6: Continue to brush your diamond while back in the soapy water so the dirt becomes looser and washes off. 

Step 7: Run clean water over your diamond, though make sure to put the plug in the drain first! 

Step 8: Dry your diamond piece with a lint-free cloth, or a hairdryer. 

How to clean a diamond ring

We all know that there’s nothing more mesmerising than watching your diamond ring dazzle and glisten in the light. That’s why it’s essential to keep it at its very sparkly best! As an engagement ring, in particular, is worn every day, it’s easy for it to become dirtied by common cosmetics such as makeup, creams, perfume and hairspray. 

The first step to take to ensure your engagement ring always shines bright is to soak it  in warm (almost hot) water and dishwashing soap or shampoo for 20 to 40 minutes. You can use a soft toothbrush to brush the stone before rinsing with warm running water. 

Note: It’s important to remember that whatever you choose to wash your ring with, make sure it’s not moisturising, as this can leave a film. You must also never use household cleaners such as bleach, chlorine and acetone, as these can break down base metals. Abrasive products such as toothpaste and baking soda can also scratch metal, particularly gold. 

When drying off your ring use a soft cotton cloth or leave to dry naturally. It’s best to avoid paper towels as they can scratch the rings metal.

How often should a diamond ring be cleaned? 

For a diamond engagement ring to stay looking beautiful, it’s a good idea to give it a clean at home once a week in order to get rid of daily oil and buildup. In the long term, it’s advised that you have your ring professionally cleaned by a jeweller twice a year. 

If your lifestyle involves spending a lot of time being active outdoors, or working in a kitchen, it’s advisable to get your ring professionally cleaned even more frequently. The jeweller will use a professional-grade product to restore the brilliance of the diamond.

How to clean a diamond tennis bracelet 

With different jewellery comes different cleaning methods. If you own a diamond tennis bracelet you will want to fully enjoy how much it sparkles on your wrist so it is important to keep it clean from any dirt and oil that it might come into contact with.

Here’s our tips on how to clean a diamond tennis bracelet.

Mix washing up liquid with warm water into a small blow. You only need about an inch of water to cover your bracelet and just enough washing up liquid to make some bubbles. You should allow the bracelet to soak for about 15 minutes.

Use a soft toothbrush to scrub the diamonds over the bowl of water. Get between the diamonds but be careful around the prongs. You should then rinse the bracelet in warm water over a mesh strainer, this way it allows you to catch any diamonds that may come loose and fall out during your cleaning process. 

Pat your bracelet with a lint-free cloth but be careful not to get any of the fabric on the prongs.

Pour your soapy water through the strainer and look out for any diamonds that could have fallen out. This method doesn’t cause them to become loose but if they were already loose without you realising then, cleaning them could cause them to come out so be careful.

Tip: Do not wear your bracelet while cleaning, showering, putting on lotion, or gardening because it will increase the residue that builds up on your bracelet.

How to clean diamond earrings 

Diamond earrings can also become dull and dirty because of frequent wear. The oil is picked up from your hair and skin which then causes the metal to become worn and the stones can sometimes come loose.

1. Buy yourself a jewellery cleaning kit. These kits contain a special solution that is designed for cleaning earrings, so you know that it won’t harm your jewellery.

Pour a small amount of the solution into a bowl, soak your earrings in the solution overnight. Rinse the earrings with warm water in the morning, dry and polish with a lint-free cloth.

2. Get yourself the right brush and cloth. You need a brush that has soft bristles. This is important because if your brush is too hard it will damage your jewellery.

Buy yourself a soft toothbrush; a child's toothbrush is probably the best type as the bristles are really soft.

Use a microfiber cloth/hand towel to dry your earrings with.

3. Do all this on a flat surface. If you clean your earrings near the sink the chances of you losing one down the drain is pretty high. So choose any flat surface that is not near a sink.

If you don't have a jewellery cleaning kit or can’t find one, there are many home products you may already have in your cupboards that will restore the shine to your diamond earrings.

Mix together one cup of lukewarm water with one teaspoon of dish soap. Stir it together until you can see bubbles. Make sure your washing up liquid is perfume or dye free because it could harm your earrings. Soak them for about three to four minutes.

Take your soft toothbrush and in the wet mixture gently brush your earrings for another one to two minutes. You should then remove your earrings and then place them on a paper towel. Get yourself a bowl of clear water and rinse the earrings off.

Another great home cleaning product is Windex. Spray this on a toothbrush and then gently brush the diamonds. Rinse them with water and wipe dry with a soft cloth.

The key to cleaning diamond earrings is to be soft and gentle. 

Ultrasonic cleaners for diamonds

Ultrasonic cleaners are often used in jewellers to professionally clean diamonds, therefore is a popular choice for cleaning diamond engagement rings that have become dull over time. Take your ring into your local jewellers and let the ultrasonic cleaner work its magic. It’s important to remember, though, that is a process used only for diamond jewellery; and secure, sturdy ones at that. Though this type of cleaner works wonders for diamonds, they should not be used on the following: 

  • Pearls, coral and ivory 

  • Coated gemstones

  • Heat treated gemstones 

  • Soft gems easily affected by heat like opal, iolite, moonstone emerald or tanzanite. 

Now you know all the best top tips, start cleaning your jewellery and watch it sparkle like the day you brought it.
