Our process involves three stages: consultation to discuss preferences and budget, CAD visualisation for adjustments, and final manufacturing with optional in-person fittings.

Do you offer returns or guarantees?

We provide a 30-day money-back guarantee with full refunds available for undamaged items, including bespoke orders if adjustments aren't feasible.

Are your diamonds certified?

All diamonds receive certification from GIA or IGI, including grading reports for cut, clarity, colour, and carat weight.

The Diamond Ring Company were professional, understanding of what we were looking for and extremely helpful and accommodating. Alex was an absolute pleasure to work with and made sure that the ring was ready in an extremely quick turnaround time. The ring is perfect - exactly what we wanted! We will definitely be using the company again for our wedding bands!

My fiance and I had a pleasurable experience getting our engagement ring designed by Michael at the Diamond Ring Company. We selected the company based on the excellent online reviews and I can confirm that the reputation is well deserved. Michael was patient and accommodating with us throughout the process of getting the ring, didnt pressure us and helped to get the best value for money. When I was unable to collect the ring due to unforeseen circumstances, Michael was empathetic and reassuring. My fiance adores the ring and we are grateful to Michael for producing such a high-quality product

I had done my own online research and was pleased to hear The Diamond Ring Company recommended to me by a work colleague. Arranging an appointment was straight forward with my emails being responded to very quickly. Michael was extremely friendly and knowledgeable. With his help I was able to find the perfect engagement ring which looked exactly how Id imagined and (thankfully) suited my own budget. Michael ensured the ring and accompanying certification was ready to collect after two weeks. My now fiance was blown away with the engagement ring and has not stopped admiring it on her hand.

I can't speak more highly of my experience working with Michael at The Diamond Ring Company. He is one of the nicest and most accommodating people I've had the pleasure of dealing with - his experience, love of the craft and attention to detail are also amazing. I wanted a bespoke engagement ring for my fiancee and he was open to all my ideas and he ended up producing something which was stunning (and which she loved and still loves). The experience was so great that we came back for our wedding rings, which again were great! I would highly recommend going with Michael and the Diamond Ring Co.

Firstly, I can see exactly why Michael at The Diamond Ring Company retains such fantastic reviews. From my initial telephone call enquiry with Michael through to selecting a ring style and diamond, and all the way through to collection he was an utter gentleman. He is one of the nicest people you will meet, no pushy sales, no gimmicks, no flashy shop front, just a patient and honest man making high quality goods at very reasonable prices. A truly personal service, I can honestly say you cannot go wrong by choosing him. Kind regards

When I started looking for an engagement ring for my girlfriend I didn't have any knowledge of rings, styles or diamonds. Once I got into contact with Alex at The Diamond Ring Company that changed everything, he explained everything in a simple way, didn't up-sell or push my budget, showed me diamond/ring examples in person and over the phone, talked me through some industry terminology/standards and together we built the dream ring my girlfriend always wanted. I can't stress enough how amazing the service is, how beautiful their rings are and how much of a good price they give compared to everywhere
