Most of you will be familiar with colourless or near colourless diamonds and these would be the most popular when a person chooses to purchase a diamond engagement ring.

Coloured diamonds are even rarer than colourless diamonds and therefore trade at a premium. What causes this colour to occur in diamonds? These colours are present due to the presence of certain trace elements such as nitrogen, boron, hydrogen etc. which were introduced when the diamonds were being formed deep within the earths mantle.
