Our excellent personal service goes beyond the moment of shopping. In the unlikely event that you’ve encountered some problems with your diamonds or jewelry, you want reliable customer service. With jewelry being a luxury item, you are in full right to expect a highly dedicated service. And with an established luxury diamond polishing factory such as Royal Coster, that’s exactly the kind of service we provide.
Our customer service is available from Monday to Friday, from 9:00 AM to 5:00 PM. Our reception is also available on Saturdays and Sundays. In our FAQ you can find the answers to most questions.
