Comment évaluer la qualité d’un diamant ?

How do you assess the quality of a diamond?

Does a diamond always sparkle brilliantly? How can you recognize an exceptional stone?

A diamond is much more than a simple gemstone; it's a true work of art, shaped by nature and perfected by humankind. But how do you distinguish a quality diamond from a more ordinary one? Discover the four essential criteria for evaluating a diamond's value and avoiding common pitfalls.


1. The 4Cs : The essential criteria for a perfect diamond

Each diamond is evaluated according to 4 fundamental characteristics , known as the 4Cs :

• Carat (Weight) : The heavier a diamond is, the rarer and more expensive it is.

• Clarity : A diamond without inclusions is extremely rare and therefore more valuable.

• Colour : The purest diamonds are classified as D (colourless) , while those with more yellowish tints are less prized.

• Cut : A perfect cut optimizes shine and light reflection.

đź’ˇ Tip: Did you know that a well-cut 1-carat diamond can appear larger than a poorly cut 1.5-carat diamond?

2. The certificate: your guarantee of authenticity

A quality diamond must be accompanied by a gemological certificate issued by a recognized laboratory (GIA, HRD, IGI). This document attests to its characteristics and protects your investment.
