Diamond – The Birthstone for April

There is a globally accepted standard for describing diamonds based on the 4 Cs: Colour, Clarity, Cut, and Carat Weight. This is the universal method for assessing the quality of any diamond, throughout the world.


Carat is the weight of the diamond and should not be mistaken for the size of the stone or gold carats.


Clarity describes how free the diamond is from inclusions which are the naturally occurring flaws found in a diamond. This also accounts for the type, positions and number of inclusions.


Colour is graded using the GIA colour guide (Gemmological Institute of America) on how close a diamond is to being colourless – colourless diamonds are generally more valuable, though special coloured diamonds or “fancies”, can be very valuable.


Shape and quality are considered when discussing the cut of a diamond. Round brilliant cut is the most popular cut.
