There are many factors that contribute to diamond and gem appraisals. It can be a complex matter. Below, you can get an overview of some of the criteria we use in determining the value of diamonds.

Diamonds are appraised using the 4 C’s: carat, colour, clarity, and cut. This is a globally recognised method developed by GIA for evaluating any individual diamond. Read more about the 4 C’s further down on this page.

We use the Rapaport Diamond Report, an internationally recognised guideline.

About diamonds

The 4 C’s:

Clarity

Diamonds often contain inclusions or small flaws, which are a natural part of the stone. “Flawless” diamonds are rare. The fewer inclusions a diamond has, the more it’s worth. Often, there are some savings to be had in choosing a diamond with small flaws — as long as they aren’t visible to the naked eye. As a rule of thumb, clarities from “FL” (flawless) to “SI1” (small inclusions) may not have any flaws that are visible to the naked eye, only under 10x magnification. However, looking at diamonds strictly as investments, the diamonds purchased by investors and experts are often flawless.

Color

The whiter the diamond, the more valuable and rare it is. White diamonds are called “River”, “Top Wesselton”, or “Wesselton”. Yellow and black diamonds are cheaper, since these colours are much more common than white diamonds. “Fancy” colours, such as pink and bluish, are generally the most expensive. New finds in these colours are rare in the mines.

Carat

1 carat equals 0.2 grams. Larger diamonds are, of course, more
valuable than small diamonds — provided they’re equal in terms of the other 3 C’s. Here, you can see how an increase in carat is associated with a larger millimetre measurement of a diamond.

Cut

The right cut ensures that light is reflected optimally, giving the diamond the most sparkle and life. Diamonds can only be cut with diamond dust, as they are the hardest known mineral.Complex formulas and programs are often used to evaluate a raw diamond’s potential before cutting it into one or more smaller diamonds.

The round brilliant cut is the most commonly used, but there are many alternative cuts that can really make a piece stand out. You can see the different cuts here:

Round Cut
Heart Cut
Pear Cut
Oval Cut
Cushion Cut
Marquise Cut
Emerald Cut
Princess Cut
