ABSTRACT:
A polycrystalline diamond is prepared by chemical vapor deposition (step 101). A surface of the polycrystalline diamond is metallized (step 102). The metallized surface of the polycrystalline diamond is grooved with a YAG laser (step 103). A wedge or the like is driven into the grooves of the polycrystalline diamond to pressurize the same, whereby the polycrystalline diamond is divided along the grooves (step 104). Alternatively, a surface of a polycrystalline diamond prepared by chemical vapor deposition is grooved with a YAG laser (step 112), so that the surface of the polycrystalline diamond is metallized (step 113) after the grooving.
