Diamond care

To avoid dulling your diamond's optimum fire and natural brilliance, it is best to remove any jewellery when using skin oils, soaps and cosmetics. The best way to keep your diamond jewellery looking pristine is to occasionally polish it gently with a soft, dry jewellery cloth.

Although diamonds are very durable, we recommend removing your diamond jewellery when carrying out strenuous work or activities to avoid it being chipped by a hard knock. To avoid tiny scratches, it is advisable to store your diamond jewellery in separate pouches from other diamonds and jewellery.

It is also important to ensure that your diamond does not come into contact with chlorine bleach as this can damage the setting. Visit your local Ernest Jones store annually to have your diamond jewellery checked for weakened or bent claws.

Our diamond sources

The source of our diamonds is an issue we take very seriously. You can be confident that concrete and comprehensive measures are taken to ensure the products we sell do not include conflict diamonds.

We require all our trade suppliers of diamonds and diamond jewellery to provide us with a warranty that they do not supply us with conflict diamonds.
