How to Assess the Value of a 1-Carat Diamond?

The value of a diamond depends mainly on three factors:

• The type of diamond
• The diamond’s characteristics (the famous 4Cs)
• The certificate associated with the diamond

For example: a so-called investment diamond (i.e., a loose, unset stone that will not be worn in a piece of jewelry) is valued less than a set diamond. Similarly, antique diamonds have more value than recently acquired ones. Finally, a round brilliant diamond will always be valued higher than a so-called “fancy” diamond, such as the princess diamond. Generally, the diamond’s characteristics are found in its grading report. The certificate associated with the diamond plays a significant role in estimating the diamond’s price. For a highly valued diamond, the best possible certificate is from the GIA (Gemological Institute of America). Next, the certificates that add the most value to the diamond are those from the LFG (Laboratoire Français de Gemmologie), IGI (International Gemological Institute), and HRD. It should be noted that below 0.5 carat, it is unnecessary to have the diamond certified when selling, or to purchase a certified diamond when buying. Other gemological laboratories, such as AIG (Antwerp International Gemological Laboratories), have a poor reputation and are often valued at 0. If you wish to sell an expensive diamond, it will be more advantageous to request a new certificate from the GIA rather than trying to sell it with an AIG certificate. The diamond’s characteristics are the last major factor in estimating its value. They include the 4Cs:

• Weight (Carat)
• Cut
• Color
• Clarity

Generally, weight, cut, and color are more important in giving a diamond value than clarity. Thus, the more perfectly cut the diamond is and the more colorless it is, the higher its value. Other characteristics may be taken into account, such as symmetry, polish, or fluorescence.
