The 4 C's

The 4 C's and the style of the engagement ring should be considered in close harmony. The type of setting of the ring should maximise the beauty of the diamond you have selected: while the 4 C's of the diamond should compliment the design you have chosen.

CUT - This comprises both the shape and proportions of the stone that the diamond polisher has been able to unveil. While the 'Round Brilliant' cut yields a diamond of symmetric proportions, fancier shapes might prove more suitable to your taste.
COLOUR - The colour of the diamond you choose may be influenced by the colour of the metal in the design of your ring. The average ranges from colourless through to dark yellow. Other colours such as red, blue and green are more rare.
CLARITY - Also referred to as the 'purity' of a diamond, is graded under x10 magnification according to universal standards. A flawless diamond will command a higher price than that of one with blemishes and inclusions.

CARAT WEIGHT- This indicates the size or weight of the diamond. The design of the ring and finger size of the wearer will be of importance when determined the carat weight of choice.
