Sorry I didn't have pictures last night. So a photographer I'm not. I rushed to cut a small stack of these diamonds, so they are not stacked as nicely as they could have been.
For this marking to show up for the camera I used a ball-point pen. Normally I would use a #2 pencil.

Piercing the mark with unthreaded needle (repeat on all marked spots)

Wiggle with needle down to enlarge pierced holes

You can now see where to stop and start at by how the holes line up
