This isn’t strictly true – there are definitely other differences between the Princess cut and the radiant – but their square shape and the brilliant cut mean that they do look very similar once mounted in a ring. Instead the GIA calls radiant shaped diamonds “cut corner modified brilliant”, which is basically saying that they are a Princess cut diamond with the corners trimmed off. The Gemological Institute of America (GIA), the world’s most prominent gem grading lab, doesn’t recognise ‘radiant’ as an official name for a shape of diamond. While other diamond shapes give different names to the square and rectangular version of them (an ‘Asscher’ cut is basically just a squared-shaped ’emerald cut’) the name ‘radiant cut’ covers everything from a perfectly square stone to one that is twice as long as it is wide.Īctually, saying that we have one name for radiants is a bit misleading. Radiant cut diamonds have some of the greatest variety of any of the diamond shapes – they can either be a perfect square, or much more rectangular.

This guide will show you how to get a top quality stone that sparkles brilliantly. With the increase in the number of diamonds being produced has come a reduction in the cut quality, and therefore the brilliance of the stones. Radiant cut engagement rings are actually a fairly recent development – the shape of the diamond was invented in the 1970s and the patent on the design only recently ran out, which meant that many more diamonds could be produced. It was originally developed to combine the best bits of the extremely sparkly round brilliant shape, the trimmed corners of the Asscher cut and the openness and elegance of the emerald cut and definitely manages to do all of this.

The radiant diamond combines the very best parts of several other diamond shapes.
