STAGE TWO : SAWING
The sawing process requires immense skill as the diamond exhibits very sensitive pressure points, and inaccuracy in any degree could result in the diamond shattering and being rendered worthless.

The marked diamond is set up in the sawing pot lined up to critical dimensions for the sawing process to commence. To saw a diamond in two can take as much as five days. In fact the first kerf can take up to 2 ½ hours alone.
The initial kerf (groove) is done with a short blade, needing to be done accurately so that that the high blade will saw through the diamond along the line of the marker.
Frans Swanepoel, an extremely experienced sawer who has been with FestDiam for some ten years, constantly checking the accuracy of the cut.
The long blade almost completely through the diamond.
