he 4Cs - Cut, Colour, Clarity and Carat - play an important role in the valuation and authentication of diamonds.

Although all 4Cs are important, the question arises as to which ones are most important when searching for the perfect diamond. In this article, we look at the importance of cut and clarity and explain how these factors can influence your choice and your budget.

The 4Cs of diamonds: focus on cut and clarity

Diamond cut: the key to brilliance

The cut of a diamond determines its beauty more than any other factor. It describes the symmetry, proportions and polish of the stone and influences how light interacts with it.

The three most important properties of the cut are fire, brilliance and scintillation:

Fire: The distribution of light in different colours.
Brilliance: The total amount of light reflected by the diamond.
Scintillation: The flashes of sparkle or light.
A well-cut diamond maximises these properties and gives the stone a breathtaking sparkle.

Diamond clarity: flawless or unique?

The clarity of a diamond refers to the number and visibility of inclusions and flaws in the stone. These inclusions can be tiny cracks, dark spots or white dots.

Whilst a flawless diamond (FL) may appear flawless, this is very rare and expensive. For most people, a diamond with SI1 or SI2 clarity, where inclusions are not visible to the naked eye, is an excellent choice and offers excellent value for money.

Conclusion: the interaction of the 4Cs

All 4Cs play a role in the valuation of a diamond. However, the cut is the most important factor for the beauty and brilliance of the stone. Clarity should also be taken into account, but small inclusions that are not visible to the naked eye do not significantly affect the value or appearance of a diamond.

When choosing a diamond, look for a good balance between all 4Cs. A well-cut diamond with a good clarity (SI1-SI2) and a colour grade of G or H can be a stunning piece of jewelry without putting a strain on your wallet.
