Choosing a round cut diamond ring

The round brilliant cut is the most popular shape for a diamond engagement ring. In fact, up to 75% of diamond rings feature round brilliant cuts, and this seems unlikely to change in the foreseeable future. If it has been well cut and polished, the round brilliant delivers unbeatable sparkle – something that never goes out of fashion.

Devised by Marcel Tolkowsky in 1919 to optimise the reflection of white light ('brilliance'), dispersion of light into different colours ('fire'), and scintillation (sparkle, which we jewellers call ‘life’), the round brilliant cut looks stunning in a wide variety of engagement ring settings. What's important is that you choose a design that takes into account the wearer's taste and lifestyle.

A guide to lab grown diamonds

Scientists first started to produce real diamonds in laboratories in the 1950s, but these were too small to be used in jewellery. As manufacturing methods improved, lab grown diamonds started to be produced in volume for industrial purposes. Still, it was not until the 1990s that larger, gem-quality crystals began to be produced. However, for […]
Diamond Certificate

Diamond certification

What is a certified diamond? If a diamond has been independently graded by a gemological laboratory and supplied with a report detailing the size and quality of the diamond, it is termed a certificated or certified diamond. Diamond certification is widely available for diamonds above 0.3ct. To cover the cost of certification, and because certification […]
Conflict Free Diamonds

Conflict-free diamonds & ethical diamonds

Consumer interest in ethical and conflict-free diamonds has been growing steadily over the last 20 years, driven by increased awareness of the horrors of 'blood diamonds', worker exploitation and environmental damage associated with diamond mining and processing. In the last five years, a dramatic increase in the availability of high-quality lab grown diamonds has also […]

Choosing the right ring size

Before you purchase an engagement ring, wedding ring or eternity ring, you'll need to decide on the size you want. Your ring should be snug enough that it will not come off your finger inadvertently but not so tight as to be uncomfortable. But choosing the right ring size isn't always easy. For most people, there are several ring sizes between uncomfortably tight at one extreme and obviously too loose at the other. This means that there is some degree of subjectivity to the question of what is the right size. Some people simply like to wear rings tighter than others. For this reason, your jeweller can advise you, but ultimately only you can say what size feels best.

I honestly cannot recommend Ingle & Rhode enough

Ben and I knew that we wanted a conflict-free and ethical diamond, and we were so delighted to find Ingle & Rhode (and I was so glad to be part of the process...!) Ellie was so warm and helpful, and clearly passionate and knowledgeable about what she does – we really enjoyed meeting her on several occasions, and she responded to all our questions and requests quickly and with such consideration; we really felt that we were getting a bespoke, personal, 1:1 process. I am beyond delighted with my beautiful Aria ring with my stunning lab-grown diamond – I'm 6 weeks engaged, and still don't stop staring at it in all different lights. Thank you so much Ingle & Rhode - you made the world of difference to us in the months before getting engaged, and we have not stopped telling people about you since.

Ingle & Rhode were exceptional throughout the whole process

I was purchasing an engagement ring, so I had a lot to learn. Their website is very useful and helps you build your own ring. I also had an appointment for initial discussions and consultations. They were great at talking through options, giving suggestions and advising on ring size. I work overseas and so the logistics were complicated but they were so flexible and helpful. Everything went well and the ring was even delivered to the house. Brilliant follow up service for additional questions and support. Beautiful products and great service.

Beautiful, ethical jewellery - can't recommend enough!

I am so glad that I found Ingle & Rhode when looking to buy my partner an engagement ring - they are superb, and the products are wonderful.

Buying an ethical ring was really important to my partner and I, and so I was immediately drawn in by Ingle & Rhode - unlike a lot of ethical jewellery companies, their rings are still very contemporary.. which was exactly what my partner wanted!

I had a couple of calls with Ellie during the process, who was so helpful - despite not having a great idea of what to go for, she was decisive and led me towards my own decisions; highly recommend speaking with the team, because they are wonderful (and lovely people too).

Can't recommend using Ingle & Rhode highly enough - my partner loved the ring that I chose, and we would definitely use them again for jewellery in the future.

My experience from start to finish was superb

I have my dream ring which is my 10 year anniversary ring and its STUNNING I can’t stop looking at it. It took about 4 months from start to finish but so worth the wait. We had to find the right diamond and it then had to match my image I had in my head for the setting. From my first phone call to picking up the ring Ellie has been fantastic and very informative along the way. Hayley, the designer was so patient with me going back and forth on design and also had amazing ideas to really elevate the ring. The product and service is truly wonderful so much so I want to buy a new piece every year ( just have to convince the hubby ;) !! Well done team I&R

Simply stunning!

I have just collected my beautiful bespoke ruby and diamond ring from Ingle & Rhode. The journey started with an email enquiry and a face to face meeting with Natalie, who was so helpful and talked through with me some ideas I already had. This ring isn't an engagement ring but more of a statement piece, and I knew that I wanted to find a product that fitted my ethical & environmental values. Hayley then took over with the design process which was so enjoyable, and I have loved watching and being involved with my ring slowly evolving from 6 initial designs. I was really happy with the final CAD artwork and now that it has been turned into the finished piece, it is simply stunning. I could not be happier with my purchase and would thoroughly recommend Ingle & Rhode to anyone looking for a bespoke design and ethical values for a special piece of jewellery, whatever the occasion. Thank you to the whole team!.
