0.25cts red heat-treated diamond engagement ring

This elegant engagement ring is simple and beautiful. This wonderful heat-treated diamond sparkles with stunning flashes of red, orange and burgundy. The 0.25cts brilliant cut red heat-treated diamond has been set in a simple 4 claw setting that also allows you to see the diamond from all angles. This design reminds Harriet of a glass of fine red wine on a winters evening - with the contrast of the intense red and icy-white of plaitnum.

The diamond uses state of the art technology - a naturally cognac coloured diamond has undergone a form of ion induction colour treatment that substantially enhances the colour of diamond and this actually changes the surface layer of diamond. The treatment means that the ring must not be heated up to very high temperatures (eg by a jeweller during resizing of the ring) or cleaned in an ultrasonic cleaner so special care needs to be taken when resizing this ring in the future and the stone must be carefully removed and re-set during any future resizing work.
