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.
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
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.
One 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.
