How to Clean a Diamond Pendant

How to Clean a Diamond Pendant

Diamond pendants are a popular piece of jewellery. They can be worn on special occasions or every day, and they add some sparkle to every outfit they adorn. If you own a diamond pendant, you want to make sure it stays sparkling and beautiful.

If diamonds are not cleaned properly, no matter the style—from diamond pendants on a chain to tennis bracelets—they can lose their shine. If you’re going to adjust any of your pieces, such as converting a diamond ring to a necklace, you need to be familiar with how to clean and care for your jewellery. In this post, we will explain how to clean your diamond pendant so that it always looks its best.

The Best Way to Clean Your Diamond Pendant

Diamonds are very durable stones, but they’re also very “magnetic” to oils and dirt. If you touch a diamond, it easily retains fingerprints and oils from your skin. Here is the best way to clean your diamond pendant:

First, gather the following materials: dish soap, a soft-bristled toothbrush, a cup of warm water, and a clean cloth. Start by mixing together some dish soap and warm water in a bowl. Then, soak your diamond pendant in soapy water for a few minutes.

After a few minutes have passed, use the soft-bristled toothbrush to scrub the diamond pendant gently. Be sure to pay special attention to any areas that seem particularly dirty. Once you have finished scrubbing, rinse the diamond pendant with warm water. Finally, use a clean cloth to dry the diamond pendant.

Besides soap and water, you can also use ammonia and cold water to loosen the oil and dirt. Create an ammonia-water mixture with a ratio of 50/50, then allow your diamond pendant to sit in the mixture for around one and a half hours. Once you remove the piece, allow it to air dry. 

Before using this method, read our article on how to tell if a diamond necklace is real — ammonia can destroy other gemstones. 

How to Keep Your Diamond Shining

After you have successfully cleaned your diamond, there are a few things you can do to keep it sparkling:

Denture Tablets

Denture tablets are a great way to clean and polish your diamond pendant. All you have to do is soak the tablet in some water, then use the tablet to scrub your diamond pendant gently.

After scrubbing the diamond pendant with the tablet, rinse it off with some water and dry it with a clean cloth. You can find denture tablets at most drugstores or online.


Vodka is not just for drinking; it can also be used to clean diamonds. Simply soak your diamond pendant in vodka for a few minutes then rinse it with clean water.

Vodka is a great option for cleaning your diamond pendant because it is strong enough to remove dirt and oil but gentle enough that it will not damage the diamond prongs. Plus, it dries quickly, so you do not have to worry about waiting for your diamond pendant to dry.

Club Soda

You can also soak your diamond in a club soda to keep it shining–all you have to do is dip your diamond pendant in a glass of club soda overnight. The next morning, remove it from the glass and rinse it off with some water.


Toothpaste is another great way to clean your diamond pendant. Apply some toothpaste to the diamond pendant and use a soft-bristled toothbrush to scrub it. After you have scrubbed it, rinse off the toothpaste with some water and dry it with a clean cloth.

Jewellery Cleaner

If you want to make sure your precious gem is extra clean, you can use a jewellery cleaner. Jewellery cleaners are designed specifically for cleaning diamonds and other precious gemstones.
