How to evaluate the value of a 1-carat diamond?

The value of a diamond mainly depends on three factors:

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

For example: an investment diamond (i.e., an unmounted, unset stone that will not be worn on a piece of jewelry) is valued less than a set diamond. Similarly, antique diamonds hold more value than recently acquired diamonds. Finally, a round brilliant diamond will always be valued higher than so-called “fancy” diamonds, 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 give the most value to the diamond are those from the LFG (Laboratoire Français de Gemmologie), the IGI (International Gemological Institute), and the HRD. Note that below 0.5 carat, it is pointless to have the diamond certified if selling, or to buy a certified diamond if purchasing. Other gemological laboratories, such as the 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 thus 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:

• The weight of the diamond (Carat)
• The cut of the diamond (Cut)
• The color of the diamond (Color)
• The clarity of the diamond (Clarity)

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