At the time of a diamond's formation tiny traces of non-crystallised carbon or other minerals and gases may have become trapped inside. These are broadly termed "inclusions" and are often referred to as nature's fingerprints. The clarity grade of a diamond is determined by the presence, size and positioning of these inclusions as they may impede the passage of light through the stone.
A diamond's clarity is determined by the degree to which it is free from naturally occurring inclusions. The fewer the inclusions, the rarer the stone and the higher the price will be.
As with all the 4Cs, there is an internationally accepted system for clarity grading, based on the size, colour and position of inclusions within a diamond.
This system is represented in the table below:
All the certificates which accompany our stones include a 'map' of the diamond indicating the exact location of any inclusions.
