Estimating the value of a 4-carat diamond
It is important to know that the value of a 4-carat diamond varies enormously from one diamond to another, depending on several criteria:
- The type of diamond
- The intrinsic characteristics of the diamond
- The certificate associated with the diamond
Regarding the type of diamond, it should be noted that some diamonds are more valuable than others:
- The so-called "round brilliant" shape is more valuable than fancy shapes (pear, princess, cushion, oval, etc.)
- A set diamond is more valuable than an investment diamond
- The older the diamond, the more valuable it is.
Regarding the characteristics of the diamond, we will base our assessment on the 4Cs to determine its quality:
- Carat (weight): here between 4 and 5 carats
- Cut: round brilliant, princess, emerald, oval, pear, cushion, etc.
- Color: from D (colorless) to Z (tinged with yellow) on the GIA scale
- Clarity: i.e., the number of inclusions and their visibility under a 10x magnification loupe: from FL (flawless, i.e., without any inclusions) to P1 / P2 / P3 (piqué).
Finally, the value of a 4-carat diamond will also depend on the grading certificate associated with it and especially on the gemological laboratory that issued it. Many laboratories around the world can issue such certificates, but few are truly recognized; among them, we find GIA (the GIA grading certificate is the one that gives the most value to the diamond), HRD, IGI, and LFG. Conversely, other gemological laboratories have a poor reputation, and their certificate will therefore have no value (this is particularly the case with AIG).
