9ct white gold engagement ring with a 0.32ct H SI marquise shaped diamond and four 1.5mm sky blue heat-treated diamonds. Coloured diamonds like this get their beautiful colours when they are heated at very high temperatures and pressures to achieve this permanent colour change. Natural occurring diamonds of this colour are very rare and cost many thousands of pounds and so this treatment process brings these coloured diamonds within reach. This also means that the ring must not be heated up to very high temperatures (eg by a jeweller during resizing of the ring) 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.

Previous bespoke ring
This ring was created in our studios in the UK and was a unique design which means it will never be exactly repeated, however the ideas behind this design could form the basis of your own unique ring.
