A tool to pry bezels away from stones:
I have found that old burs are great for this task, but, of course
you have to modify them. Take an old round bur and grind it away on
two sides parallel to each other to create a flattened fan-shape.
Then grind away the remaining bur edge. After this is done you must
make the edge into a knife edge. Do this by grinding one side of
the “fan” making one side rounded while the other side stays flat.
Polish the bur sides so the stone and bezel are not scratched.
Place the bur in a pin vise and use the knife edge to pry the edge
of the bezel away from the stone, keeping the flat edge toward the
stone. The size of the bezel will determine the size of the bur you
need to use, but I found the most useful size was about 2.75 mm.
After you make and use the first one you will find that the burs can
be modified in all sorts of ways to make just the right tool for
many bezel sizes and stone shapes.
This tool is best used on silver bezels. Gold is generally too hard
to move after it has been work hardened over a bezel, unless it is a
thin, tall bezel.
Hope this is clearer than mud. And, never throw away a dull or
broken bur. You never know what you can use it for. Any other uses
for old burs?
