The 4C’s of Diamonds


Only diamond cuts diamond and when a rough diamond is cut and polished up to 72% of the stone is lost in the process.


The colour of the diamond is determined by the different gasses present during the crystallization process.


Diamonds contain minute traces of inclusions, these consist of non-crystallized carbon, cracks, bubbles, feathers, clouds etc.


The word carat was derived from the carob seed, each carob seed weighs very close to 1 carat.

The captivating beauty of a diamond is in its ability to reflect light and sparkle like no other precious jewel can. ‘Cut’ with diamonds is not to do with the diamond’s shape, such as pear, oval, or round, but rather to do with how close to optimal the placement and proportion of the many facets of the stone is. The more skillfully the diamond has been cut, the more fire and brilliance will be apparent. Diamond graders work under laboratory condition to analyse how close a diamond has been cut to the ideal proportions. The grade the diamond is then given is referred to as the ‘Cut’ of the diamond ranging from ‘Excellent’ (perfect), ‘Very Good’, (indistinguishable from Perfect unless you’re an expert) At Grace Diamonds, we strive to provide diamonds that have maximum brilliance and beauty.


Almost every diamond has impurities called ‘inclusions’ or ‘blemishes’. The closer the diamond comes to flawless, the greater the value placed on it. These inclusions are often so tiny that they cannot be seen without 10x magnification. When buying a diamond, one should strive for at least eye-clear, that is inclusions that cannot be seen with the naked eye.


The colour of a diamond or rather the lack of it, is indicated by using an alphabet scale ranging from D = colourless to Z = very yellow or brown. Colour grading is done by measuring diamonds against a master set of stones under strict lighting conditions. Very subtle colour differences make a big difference to diamond value, but often they are so minimal that they are barely visible to the untrained eye and there is tremendous value to be had in the midrange of the scale.


Diamond carat weight put simply tells you about its size. Diamonds are already rare, and as size and carat weight increase, they become more scarce. At Grace Diamonds, our promise is luxury at an affordable price, which means we offer the best diamonds at a price that won’t break the bank. By adhering strictly to the standard set out by the 4Cs, and aiming to deliver the highest quality in luxury jewellery, the Grace Diamond experience is as unforgettable and high-class as the diamond itself.
