At Royal Coster Diamonds, we believe that fine jewelry should be treated with the utmost care and attention. That's why we offer a lifetime yearly walk-in cleaning service for all of our jewels, to ensure that they stay sparkling and beautiful for years to come.
Our cleaning service includes rhodanizing of rings to restore their shine and protect them from tarnishing.
At Royal Coster Diamonds, we are committed to providing our customers with the highest level of transparency and trust. That's why all of our jewels come with a Royal Coster Diamonds Certificate of Purchase and Authenticity.
