Fantastic from start to finish. The shop is located in a beautiful part of London which is easy to get to. Inside the shop itself I felt comfortable and relaxed. Being the first time buying an engagement ring I thought I might feel pressured but that was not the case. After ordering the ring communication was great throughout and delivery was on time. Upon opening the box I was taken aback by the how flawless the ring looked. I was genuinely lost for words. Thanks to all the staff at Ingle and Rhode that helped me pick the most perfect ring.

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 and Rhode highly enough - my partner loved the ring that I chose, and we would definitely use them again for jewellery in the future.

Excellent process for bespoke engagement ring Excellent process, from start to finish. I emailed to begin the process of designing a bespoke ring. Within 2 days I had an in person meeting to discuss ideas. I was shown some examples and given brilliant advice by Ellie, who I found extremely reassuring throughout. The designer, Hayley, sent me initial sketches 1-2 weeks after the in person appointment. Hayley was very patient and again provided brilliant advice. Hayley was quick to create new design iterations based on my feedback. After many back and forward emails, the design was finalised and CAD mockups were provided. The mockups were extremely accurate when comparing with the finished product. The entire process, from first email to collection, took 6 weeks for a bespoke ring made with recycled platinum and a beautiful pear diamond (which was 2-4 weeks faster than their estimate). Communication was excellent and they were very keen to fit deadlines around plans I had in place. Ring resizing was required (my estimations were 4 sizes off!). I rang to book an appointment for a professional measurement and was able to meet the same day with short notice. The ring is to be collected within 7 working days. Overall the entire process was excellent. I felt very well looked after, very reassured and found all staff genuinely trustworthy. Above all else, my partner loves the ring and we are both extremely happy.

From Russia With Love Cannot express how grateful I am to have ended up using Ingle & Rhode to construct an engagement ring for my now fiancé! I was absolutely clueless how to go about finding a ring but quickly realised I knew what style I wanted and enquired about designing and constructing a ring. From the moment Ellie got in touch she made the whole experience effortless and with Hayley's design help produced drawings of a ring that were exactly what I had pictured - all this achieved via email from an oil rig in Eastern Russia! I received the ring once home and upon opening the box I could not believe Ingle & Rhode were able to turn a few emails into such a perfect and incredible ring that was just a thought I my head only weeks before. We are now very happily engaged and the ring could not mean more to us given the nature of how it came to be and what it now represents. Once again, I cannot thank Ellie enough. All the best Ally

Perfection. From the initial meet to the final ring, ever step of the process was incredibly. I surprised my (now) fiancé with a diamond ring and everything was perfect. Would highly recommend to anyone who is looking to get an engagement ring for their partner.

Why is ethical sourcing so important?

Without proper ethical sourcing, you may unwittingly buy a blood diamond, helping finance criminal armies in war-torn areas. The only way to guarantee a diamond is ethical is to go beyond the flawed  Kimberley Process and trace it to its source, which we do for all of our diamonds.

Ethical sourcing also means protecting the environment and human rights, which is why we use recycled or Fairtrade gold, as well as Fairmined silver and recycled platinum.

How to choose a round brilliant cut diamond

The round brilliant cut is the most popular shape for a diamond engagement ring. 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. We’ve provided some guidance below to help you decide whether a round brilliant cut diamond is the right option for you, but you may also wish to read our general guidance on diamond grading.

round brilliant cut diamond plot

Optimising reflection and refraction

The round brilliant cut diamond consists of 58 main facets: 33 on the crown (top half of the stone), and 25 on the pavilion (bottom half of the stone). Often, extra facets are added around the the girdle (the widest part of the diamond, where the crown meets the pavilion).

The pattern of facets was devised by Marcel Tolkowsky, a Belgian maths student whose family owned a diamond business. In 1919 Tolkowsky published his thesis, “Diamond Design: A Study of the Reflection and Refraction of Light in Diamond”. He had looked at the way that light is reflected within a diamond, and designed the round brilliant cut to optimise the combination of ‘fire’ (refraction of light into different colours) and brilliance (reflection of white light). A well made round brilliant cut diamond will also exhibit exceptional scintillation (sparkle), which jewellers call ‘life’.

Tightly defined proportions

Round diamonds existed before Tolkowsky’s innovation, but these ‘old cuts’ or ‘old European cuts’ were shaped differently to the round brilliant – they tended to be deeper, they generally had a smaller table facet, and an open culet (the tip at the bottom of the stone). Rather than work to a rigidly defined formula, a cutter was allowed some flexibility to maintain as much of the rough weight as they felt was sensible. Looking at old cuts, you can expect to see significant proportional variations. Over the last few decades, many of these older diamonds have been recut to modern round brilliant.

Unlike an old cut, the proportions of a modern round brilliant are tightly defined. If a stone deviates far from the theoretical ideal, it won’t score a high ‘cut grade’. For example, if a stone has been cut too deep or too shallow, light will tend to ‘leak’ out of the back of the stone, and it won’t sparkle as well as it should do. 

Round diamond proportions and anglesOne area which is subject to some debate is the ideal width for the table facet (expressed as a percentage of the diamond’s width across the girdle, its widest point). A smaller table allows for more ‘fire’ or rainbow light, but comes at the cost of some ‘brilliance’ or return of white light. Tolkowsky was aware of this trade-off, and different opinions exist as to what exact table width produces the most aesthetically pleasing diamond.

Aside from this, there are very few areas where cutters are afforded significant latitude if they want to achieve an ‘Excellent’ or ‘Very Good’ cut grade.

Priced at a premium to other diamond shapes

Partly because rough diamonds tend to be octahedral in shape, and partly because of the limited scope to adapt the proportions of a round brilliant cut diamond, a diamond cutter would be doing well if he retains 50% of the rough weight in the finished stone. For this reason round brilliant cut diamonds tend to trade at a premium, sometimes costing 30% more than comparable diamonds in other shapes. In spite of this, there is never any shortage of demand!
