Diamond Engagement Rings, Eternity Rings, Wedding Rings & Diamond Jewellery



Unlike our competitors, we do not work from mass produced mounts, we master every piece, we 3D print each piece to the precise dimensions of the diamonds and coloured gem stones selected and used. Our products are on average 25% heavier than the mass produced items sold by others. The difference in quality and balance achieved is remarkable, however please don't take our word for it

About Us

Very much a family affair

Over 50 years in diamonds, this father and son business historically served the trade, supplying diamonds and diamond jewellery to the very best jewellery manufacturers and retailers, in the UK, Australia, the States and Germany. Indeed we still do have a healthy trade business and are open to new trade enquiries.

Our very first website was a business-to-business diamond sourcing website and was launched in 1994, the very day the Internet went WYSWYG. We became consumer facing in 2002 and made our online name as diamondgeezer.com but changed the name to ComparetheDiamond.com when the world lost its sense of irony.

Dragon Slayers? It's true, in 2009 we turned down the highest-ever offer made on the BBC's Dragons' Den at the time. Inevitably those cheeky Dragons, James Caan, Theo Paphitis and Peter Jones wanted too much of our established family business.

Use our skill and contact and we promise you a unique shopping experience, unquestionable value, remarkable product quality and amazing choice. The average diamond passes through 11 pairs of hands from source to consumer, we have reduced that journey down to just 2 to 4 middle men.

A family business


We have been designing and making fine diamond jewellery for over 50 years, procedures and technology have changed but the driving forces remain the same and are based firmly on knowledge, experience, skill and of course the immense talent of our designers. The whole procedure is simple, fast and efficient. Our opposition is quoting weeks to do what we achieve in days. That level of efficiency is achieved through massive experience and intelligent, unique systems and procedures
24 hours
How long does it take?

We aim to have photo realistic images, as per the example above and/or a video of your unique design with you and indeed approved by you within 24 hours.

14 Days

Our aim is to have your designer piece made and completed and on your or their finger, neck, wrist or maybe ears within 14 days of you approving the design.

10 minutes

First we chat, that's via phone, Zoom, WhatsApp or our web site Live Chat, just click the bottom right-hand corner of any of our web pages. You will be talking to one of our design and diamond experts, each with a minimum 20 years’ experience in fine diamond jewellery and they will be working with you, guiding your creation from start to finish.


If you already have design ideas and needs then simply upload or email sketches, images, drawings, photographs and a narrative and let us get started.


If you are not sure what you are looking for, we will instantly create a mood-board with hundreds of ideas to inspire. Swipe right to like, left to dismiss. We will use both likes and dislikes and using this very powerful information we can start design work with a clear direction and have the first photo-realistic images for your feedback with you within hours.


After initial introductions we will explore ideas, needs, timing and budget. Usually at this time we will identify which stone or stones will be the star of the show, not just type and shape, but the actual diamond or coloured stone, because the design will be created to the actual dimensions of the chosen stone to an accuracy of 1/10th of a millimetre.


Once the brief is clear our designers go to work. Many, many hours of dedicated computer-aided design work now follows. They are not merely creating pretty pictures but the actual production model from which we 3D print the production master. We don't charge for the design work, it is our speculative investment in the job and is a demonstration of our skills and an assurance for you that you are indeed working with the right people.


We will create a unique online private, dedicated 'viewing-room' for you, here we will share photo realistic images of your completed design and if required a video of the finished piece. Explore with smart-phone, tablet, laptop or desktop machine.


We will accommodate and action any tweaks or changes you require as the design evolves into you unique and special piece. You will be working with photo-realistic renders of the actual production model which, once approved will be 3D printed to an accuracy of 1/10mm.


Once we have final design approval production will commence. There are 12 processes involved in making your special piece. Fear not we will not disappear into a black hole during the 2 weeks of production, you will be advised of the progress as your design moves around our onsite workshop and joins the queue for the next artisan's skill set.


When completed and passed the final quality control inspection the piece is on its way and will be with you the very next day if you are in the U.K, allow a couple of days if you are outside the U. K.
