Diamonds and the Four C's
 
Understanding diamonds requires knowledge of the four C’s: cut, colour, clarity and carat weight. It is the interplay of these various characteristics that will determine a stone’s beauty and value.
 
Colour
Many people think of all diamonds as white although they actually vary considerably in colour and in fact most diamonds carry a slight yellowy colour. As well as the more common stones, diamonds can also be found in deeper colours known as fancy colours, although these are very rare. Fancy colours in diamonds include yellow, green, brown, blue, orange and pink.
