How to maintenance and clean your diamond jewellery? 3 pieces of advice from our experts

As one of the hardest materials in the world, a diamond can withstand a lot. But to keep them shining forever, it's important to maintain and clean diamond jewelry properly. Royal Coster experts provide you with three valuable tips to maintain and keep your diamonds clean.

1. Keep it clean

Jewelry that is worn daily naturally gets dirty. There are multiple diamond cleaning methods. Regular polishing with a soft microfiber cloth can make a significant difference. Note: Avoid using high-pile microfiber cloths as they can catch on the setting of your jewelry and leave fluff behind.

When the diamonds start losing their brilliance, it's time for a cleaning. There are different cleaning solutions for diamonds. You can soak the jewelry in lukewarm water with a little dish soap at home. You can add a few drops of ammonia if desired. Use a soft toothbrush to reach the lower facets, then dry the jewelry with a dry cloth or cold air from a hairdryer.

You can also visit Royal Coster Diamonds for a thorough cleaning with our Resparkle Service.

2. Handle with care

Jewelry is made to be worn, but it should be handled with care. Diamonds can withstand a lot, but they can still chip. In addition, all diamonds purchased at Royal Coster Diamonds are set in 18-karat gold, which means the gold can get scratched. Don't worry, a professional jeweler can easily clean and polish your jewelry.

Our experts recommend taking off your jewelry during the following activities:

  • Engaging in labor-intensive work
  • Taking a shower, bath, or visiting a spa
  • Sports and fitness activities
  • Gardening

3. Have your jewelry regularly serviced by a jeweler

One of the most important tips is regular diamond inspections. Our experts recommend having your jewelry checked by a professional annually. They will clean, examine, and re-polish the jewelry, ensuring the preservation of diamond brilliance and shine. At Royal Coster Diamonds, we offer this service as the Resparkle Service.
