Diamonds are chemically pure in that they are made entirely of carbon. However, they can also have trace elements that cause them to be black, white, and absolutely every colour in between. Typically, the less colour a diamond has, the more pure and rare it is, the higher its intrinsic value. That said, coloured Diamonds are even more rare!

The standard Diamond colour scale is broken into segments.It starts at D - a complete lack of colour and ends at Z – light (yet obvious) colouration. The colouration referred to in the standard scale deals with traces of yellow, brown and grey. Traces of nitrogen within Diamonds causes them to appear yellowish or brownish and traces of hydrogen causes a greyish colour.
