Diamonds come in an array of different colours, such as pink, blue, and yellow, all of which have an effect on price. The rarer the colour the higher the price. Most gem quality diamonds are in the white to yellow spectrum ranging from colourless (the absence of colour) to slightly tinted yellow. These diamonds are graded using the alphabet starting with the letter D for colourless, and then E, F, G...etc as the stone becomes more tinted with yellow. This scale is only used for the spectrum of white to yellow. All other coloured or "fancy" diamonds have their own descriptions such as "Fancy Intense Purplish Pink"!

Clarity describes the purity or the inclusions and imperfections that can be found within a diamond. All clarity grading is done under 10 times magnification, using a special magnifying glass called a "loupe". Diamonds are graded according to the size and location of the internal features. The fewer inclusions that can be seen, the more expensive the diamond.

The cut is the only one of the 4Cs to be influenced by man. The other "3Cs" namely the clarity, carat, and colour are determined by nature! The cut is what gives the diamond its brilliance and fire, and is an extremely important feature to consider when purchasing a diamond.

The proportions and symmetry are written on the certificate and can range from poor to excellent. 4Cs Diamonds highly recommends that you purchase your diamond with a certificate issued by a reputable gemmological laboratory.
