This is a natural radiant cut diamond of 2.01 carat, colour Fancy Yellow, clarity SI-1, with a GIA certificate. It comes from Royal Coster Diamonds in Amsterdam, the oldest still operating diamond polishing house in the world, founded in 1840.
The cut. The radiant cut is rectangular or square with cropped corners. It has the outline of an emerald cut but the facet pattern of a brilliant, so it returns much more sparkle than a step cut. The cropped corners make it less vulnerable than a princess cut.
Colour. This is a natural fancy coloured diamond. The colour is part of the stone itself and is described on the certificate. In fancy diamonds the colour, not the absence of it, determines the value.
Clarity. SI-1 stands for Slightly Included. The inclusions are visible under 10x magnification. Our diamond specialists can tell you where they are located in this stone.
Certificate. The diamond was graded by GIA, an independent laboratory. The certificate confirms that the diamond is natural and records its weight, colour, clarity and cut.
Setting. We can set this diamond in a ring, earrings or a pendant in 18K white, yellow or rose gold. Our diamond specialists advise you in our boutique in Amsterdam or online.
Please note. The image shows a rendering of this diamond shape, not a photograph of the stone itself, so colour, clarity and proportions of the actual diamond may differ from what you see here. The specifications and the certificate are leading: they describe this exact stone. Our diamond specialists will gladly send you photos or a video of the diamond, or show it to you in our boutique in Amsterdam.

The 4C's
The 4C's of a diamond are the four key characteristics that determine the quality and value of a diamond: cut, carat weight, color, and clarity. Together, these four characteristics are used to evaluate the quality and value of a diamond, and are considered when determining a diamond's price.
Carat
The weight of a diamond is expressed in carats and points (1 ct = 100pt). ‘Carats’ come from ‘Carob’ seeds, which were originally used for their constant weight in nature (1 ct = 0.2 g). The carat and the color are the factors that influence the most the final price of the diamond.
Clarity
The clarity is a gemstone's relative freedom from internal imperfections. These imperfections are observed with a x10 magnifier ('loupe') and affect the final value of the diamond differently.
Color
Diamonds are found in nature in different colors. White diamonds can be more or less yellow and are categorised with a letter between D (commonly known as ‘River’) to Z . The different naming systems vary depending on the certifier. Diamonds are also found in all colors; the rarest colors are classified as Fancy-colored diamonds.
Cut
The cut is the diamond’s shape. A cut grade describes the proportions of the cut and the quality of its symmetry and polish. A perfect cut makes the best sparkle.
