1.01 Carat Radiant Cut Diamond, CRY-J, SI-1, GIA Certified

This is a natural radiant cut diamond of 1.01 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. 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. 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.
