In this second mini-video, I explain in great detail what happens when I use a H.S.S. 90 degree angle setting bur. In this video I also show what a piece of metal called ‘shards’ can be formed during the ‘bearing-forming.’ process. There many methods in removing them, I will show you two of the easiest. If your stone has a thicker girdle, again more explanation in preparing the bearing for that diamond.
