Abstract: Cut product manufactured from a rough (semi) precious stone material, more particularly from diamond, comprising a lower part (pavilion) with a bottom end (culet); an upper part (crown) with a number of facets and a top end (a point with table width 0 or a top surface (table) with a table width); and a girdle between lower part and upper part, wherein the lower part comprises a number of girdle pavilion facets which describe a first angle a1 relative to the plane of the girdle and a number of culet facets which each describe a smaller second angle a2 relative to the plane of the girdle; wherein the average second angle a2 lies between 28 and 38 degrees; and wherein the ratio of the table width and the width of the girdle is 0 to 0.40.

Abstract: Cut product manufactured from a (semi) precious stone material, more particularly from natural or synthetic diamond, comprising a lower part (pavilion) with a bottom end (culet); an upper part (crown) having a number of girdle bezel facets and a top end (a point with table width 0 or a top surface (table) with a table width); and a girdle between said lower part and said upper part, wherein said lower part comprises a number of girdle pavilion facets which describe a first angle ?1 relative to the plane of the girdle and a number of culet facets which each describe a smaller second angle ?2 relative to the plane of the girdle; and wherein the girdle bezel facets are in a twisted position with respect to the girdle pavilion facets in the sense that the bezel facets have perpendicular bisectors which are not coplanar with the perpendicular bisectors of the girdle pavilion facets; and wherein the ratio of the table width and the width of the girdle is 0 to 0.40.
