<p>Provided is a diamond polishing device that is capable of preventing damage of rough diamonds by limiting the generation of impact forces between the polishing plate and the rough diamond. The diamond polishing device is provided with: a polishing plate (40) having a polishing surface (41) that rotates horizontally; a holder (10) that holds a rough diamond, which is the object of the polishing, in contact with the polishing surface (41) of the polishing plate (40); and a screw base (20) that supports the holder (10). The holder (10) has two supporting parts (11A, 11B) that are supported on two screws (21A, 21B) that stand on the screw base (20), and a mounting part (12) on the tip of which the rough diamond is mounted. By rotating each of the screws (21A, 21B), the positions of each supporting part (11A, 11B) with respect to the respective screws (21A, 21B) in the axial direction can be adjusted. For the polishing plate (40), the surface roughness of the polishing surface (41) is 1 µmRa or less.</p> |
