This is a natural round brilliant cut diamond of 2.07 carat, colour Crystal J, clarity VVS-2, with an HRD certificate. It comes from Royal Coster Diamonds in Amsterdam, the oldest still operating diamond polishing house in the world, founded in 1840.
The cut. A round brilliant has 57 facets: 33 on the crown and 24 on the pavilion. The proportions of this cut were worked out mathematically in 1919, with one goal: light that enters through the top should be reflected inside the stone and leave through the top again. That is why a well cut brilliant looks bright across its whole surface.
Colour. Crystal J is near colourless, at the lower end of that range. The stone has a slight warmth that can be visible in a white setting. In yellow or rose gold that warmth blends in with the metal.
Clarity. VVS-2 stands for Very Very Slightly Included. The inclusions are so small that even a trained grader has difficulty finding them under 10x magnification.
Certificate. The diamond was graded by HRD, 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.
