1. A method (10) for coring (21) and slicing (22) a Chemical Vapor Deposition, CVD, diamond product (11), the product (11) comprising a diamond (11a) and graphitized material (11b) covering a plurality of side-faces of the diamond (11a), wherein the method (10) is performed by an apparatus (30) providing a laser beam (14) coupled into a pressurized fluid jet (13), and wherein the method (10) comprises:
for the coring (21), cutting the product (11) with the laser beam (14) to remove the graphitized material (11b) from the side-faces of the diamond (11a);
for the slicing (22), cutting off one or more slices (12) from the diamond (11a) with the laser beam (14).
