The 4Cs of diamond grading - cut, colour, clarity and carat weight

Inclusions and blemishes are very common in diamonds, but they do have an impact on their value. Clarity is one of the factors that affects a diamond’s value, but it is not the only one. Since diamonds are the most prestigious and precious gemstones, they are subjected to a very thorough valuation. Value determination is based on four factors, known as the 4Cs, which stand for: carat, colour, clarity and cut.

Carat weight: This factor is the easiest to determine, as the stone just needs to be weighed. 1 carat is defined as 0.2 grams and the diamond’s value increases with weight. However, the value does not increase in a linear way, as large diamond crystals are much rarer than smaller ones. That is why a 1 carat diamond will cost more than twice that of a 0.5 carat diamond, assuming their quality is equal.

Colour: Most stones are pale yellow, and the range of colour distinctions from white to yellow are so subtle that they can be difficult to see. The colour distinctions cannot be described by the usual colour names, so a colour scale is used. The most commonly used is from the GIA: the "GIA Colour Scale". There are no ‘good’ or ‘bad’ colours of diamonds, just rare and less rare colours.

Clarity: Clarity and transparency vary greatly from stone to stone. If there are too many inclusions and blemishes in a diamond, it can reduce the transparency to the extent that it cannot be used as a gemstone, but instead can only be sold as an industrial diamond. Very few diamonds are flawless, and these are extremely rare and precious.

Cut: The cut of a diamond is a man-made factor. While the other Cs can be described as rarity factors, cut is more of a quality factor. A diamond’s appearance only truly comes into its own once it has been cut.
