Fairtrade red gold Twist ring with Argyle cognac diamond


A modern rose gold 'Twist' engagement ring, set with a stunning 0.63 carat pear shaped cognac Argyle diamond. Hand-forged from 18-carat Fairtrade red gold bar, the ring tapers and twists around the finger to form an open band. At one end the cognac-coloured Argyle diamond is set in an open bezel, while the other end tapers to a delicate flick. The metal has been brushed to a soft satin finish, which emphasises the colour of the Fairtrade red gold.

The 0.63ct GIA certified diamond is beautifully cut and perfectly proportioned for the design of this ring. With clean lines and a stunning coloured diamond, this signature piece from McCaul’s Fairtrade collection would make a striking engagement ring. Crafted to last generations, this ring is perfect for everyday wear. 

This Fairtrade rose gold and cognac Argyle diamond engagement ring can be worn on its own or paired with a matching Twist wedding band. Twist wedding bands are hand-forged and fitted perfectly to the curve of the engagement ring. If desired, they can be pave-set with diamonds
