0.43cts Infinity Diamond Engagement Ring

Our infinity diamond engagement ring is perfect for those looking for something a little unconventional. A 0.43ct round brilliant cut diamond is set within a demi-flush setting, which sits low to the finger and making it the perfect ring for everyday wear. Not only is your stone certified by the International Gemological Laboratory (IGL), but it actually has the measurements of a full half-carat diamond. Your diamond has also been graded K colour and SI1 clarity by the IGL, making it both a beautiful and sizeable stone. The double split shoulders on this design create a contemporary design, gliding down the finger into a perfect infinity-like design. This engagement ring is at an unrepeatable special offer price. Created in 950 platinum and in a finger size O1/2, your ring is available for immediate dispatch. It will be delivered straight to your door by a secure courier, presented in our beautiful bespoke packaging.

A Note on Diamond Cut Grade


We are regularly asked about the diamond cut grade of our diamonds. We will always provide a minimum cut grade of 'Very Good.' For fancy shaped diamonds (Princess, Emerald Cut, Pear-Shape, Marquise etc.) where cut grade does not appear on the certificate (under the GIA system) we ensure that an equivalent standard of cut grade is maintained.
