Summary:The invention relates to a method and an apparatus for manufacturing a workpiece (101), specifically a rough diamond, into a product, specifically a brilliant. The method is performed by an apparatus providing a laser beam (103) coupled into a pressurized fluid jet (104). The method comprises executing multiple cuts of the workpiece (101) with the laser beam (103) according to a predetermined cut-sequence (107) to remove workpiece (101) material with each completed cut. The method further comprises executing multiple rotations of the workpiece (101) around the same axis of revolution according to a predetermined rotation-sequence. Thereby, a rotation is executed after a completed cut, and for executing a cut the laser beam (103) is moved along a two-dimensional path.
