Tips on the process of flush setting?

Hi there! I’m learning how to flush set diamonds. I am having
trouble with getting the stone unstuck if the seat isn’t the right
size. How do you get a stone “unstuck” in order to correct the seat.
Also, could any one give me tips on the process of flush setting?

a nice waxed piece of dental floss or tape does it for me…lay it in
before the stone. It compresses well enough to check the level,
depth of bearing, etc…

I know many prefer a tight fit of the diamond in the seat. However I
like a just slightly loose fit. The reason being if you force fit the
diamond you run the risk of breaking the girdle. Also if the stone is
just a little bit loose you can see your progress as you tighten it
and know that its not just the press fit holding the diamond in
place. Remember to drill out the hole large enough so that your stone
is not resting on the main part of the pavilion but just at the
girdle. To tighten I start with a medium point (but it depends on the
size of the diamond) carbide burnisher held at an angle so that the
metal plows over onto the stone. I finish off with a finer point and
an end brush if needed.

And if you get in the frustrating position of having the stone set
so its in there and won’t come out but its still a tiny bit loose,
its cheating but, you can go in with a fine point tool behind the
stone to raise the seat a tiny bit.
