They were extremely helpful in answering all my queries. My ring arrived as quickly as they said it would, and it was absolutely stunning.


The ring is stunning. I have honestly never seen ring that sparkle and shine like this ring does. I contacted them a few times during the process and always received clear and prompt responses. Highly recommended!

Outstanding customer service. My issue was dealt with quickly and efficiently. I had to send off my fiancés ring for inspection, and Created Brilliance could not have been more fantastic - sent me a prepaid label to return the ring, emailed me less than 24 hours later with details of the replacement and then the ring arrived back with me Special Delivery by 1pm. In total, I think it took about 4 days total to resolve and replace the ring. Absolutely wonderful, could not recommend more highly.
