If your bezel split when you tried to close it, it may be that the
bezel is higher than needed. If it is only just as high as it needs
to be to hold the stone in, you shouldn't have to push it very far
before it contacts the stone.
Second, try pushing on the corners first. It is difficult to push
the corners down to the stone, but it is much harder to do it after
the sides are down.. If you close the corners first, then move on to
work on the sides, you should get a neater look.
If they still come apart, there is probably a problem with the

you are constructing the bezel from four pieces with seams at the
corners. If this is the case, those corners are going to be very
stiff. You might make your bezel out of one piece, with the seam in
the center of a side. If you are using thick material, you will need
to cut/score along the bend line halfway through or more with a
separating disc or one corner of a square file to get a neat, sharp

about what you're doing (I don't have the book you
