Coloured diamonds, or “fancy” diamonds are something really special and often very valuable. If you’re thinking about one for your engagement ring then you’ll probably be thinking about how much you want to spend before anything else.

Colours available are yellow, cognac, green, brown, pink, orange, blue, black and purple and each has its own special characteristic.

Naturally Coloured Diamonds

Naturally coloured diamonds are very rare and can be an expensive purchase. Naturally occurring yellow diamonds are more readily available, whereas blues, greens and reds are very rare and sought after.

Heat Treated

These stones have been put under huge pressure and heated to very high temperatures, before they are then sometimes ion infused in a laboratory. This treatment produces a fabulous range of colours including blues, greens, pink and yellow.

Its important to remember that heat treated diamonds have to be handled carefully and cannot be reheated otherwise the colour will be lost. This means that if your engagement ring needs resizing, your diamond must be removed while the work is carried out.
