0.55 Carat Brilliant Cut Diamond, CRY-J, SI-1, GIA Certified

This is a natural round brilliant cut diamond of 0.55 carat, colour Crystal J, 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. 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. 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.

The specifications and the certificate are leading: they describe this exact stone.
