摘要： A method of determining an optimal target gemstone to be obtained from a rough gemstone comprises obtaining a first series of 2D images of the rough gemstone; providing a 3D model of a target gemstone to be obtained from the rough gemstone; and generating a second series of 2D images of the target gemstone from the 3D model thereof. The method then comprises comparing the first and second series of 2D images to determine an optimal transformation to be applied to the 3D model of the target gemstone.

摘要： A gemstone includes a crown, a pavilion, and a girdle disposed between the crown and the pavilion. The girdle has a pear-shaped cross-section with a rounded end a tapered end narrower than the rounded end. The surface of the gemstone is generally divided into a number of groups of interlocking facets disposed at a variety of angles. The groups of facets comprising the surface of the crown generally include star facets, upper intermediate crown facets, lower intermediate crown facets, main crown facets, and upper girdle facets. The upper girdle facets generally abut an upper edge of the girdle. The groups of facets comprising the surface of the pavilion include culet-adjacent facets, candle facets, main pavilion facets, and lower girdle facets. The lower girdle facets generally abut a lower edge of the girdle.

摘要： The present disclosure relates to the field of Chemical Vapor Deposition (CVD) diamonds and their processing after fabrication. In particular, the present disclosures provides a method for coring and slicing a CVD diamond product, wherein the CVD diamond product comprises a CVD diamond and graphitized material covering several side-faces of the diamond. The method is carried out by an apparatus that provides a laser beam coupled into a fluid jet. The method comprises, for the coring, cutting the product with the laser beam to remove the graphitized material from the side-faces of the diamond. Further, the method comprises, for the slicing, cutting off one or more slices from the diamond with the laser beam.

摘要： A circular cut diamond (10) comprising a girdle (20), a crown (30), and a pavilion (40). The crown (30) comprises a circumferential succession of eight main crown facets which extend upward from an upper edge (23) of the girdle at a crown angle which is greater than 19° and less than 25°. The pavilion (40) comprises a circumferential succession of eight main pavilion facets which extend downward from a lower edge (24) of the girdle at a pavilion angle which is greater than 41° and less than 43°. The circular cut diamond (10) can compete with the brilliance of an ideal cut diamond without a significant compromise in carat weight.
