Red Diamond
Natural red fancy colour diamonds are the rarest of the coloured diamond collection and are highly valued. Some say there may be less than 20 true red diamonds in the world. Only a handful have ever received the grade of fancy red, a red diamond in its purest form. Its red colour is caused by a process known as ‘plastic deformation’, a slipping or distortion of the atomic lattice.
Please note that a significant amount of treated diamonds exist on the market. The purpose of the treatment is to increase the colour.
