In the case of the ring that we are making
today we are going to use a cabochon moonstone and a silver bezel setting for a cabochon
but where we are using a setting such as this platinum tapered bezel we would have to cut
a seat perfectly to match it so the first thing that we would do is take our gemstone,
say something like this sapphire right here, drop it in to our measuring tool, measure
the exact size and this happens to be exactly a 4 and 1/2 mm stone and then we would use
an exactly 4 and 1/2 mm setting bur to cut a seat that would match that perfectly. But
in the case of today’s cabochon setting we don’t need to cut a seat because the mounting
already fits it perfectly. If we were setting that faceted stone into this tapered bezel
were it in a ring or an earring or a pendant or anything we would use an exact size bur
with a flat side such as this one that happens to be exactly 4 and 1/2 mm and we would cut
a seat right into the setting. Now we want to cut this deep enough so that the top of
this bezel will roll over relatively easily and will protect it but not so deep that you
bury the stone inside the setting. Another important factor to think of is how thick
the walls of the setting are going to be because after you are finishing it you don’t want
to cut your way through the file or polish your way through the edge of the stone. The
ring that we are working today is a cabochon style setting and to prep the bezel a little
bit I’m going to drop this ring right into my GRS bench mate which is a really handy
tool for anyone who is looking for a great vice for their bench. I’m actually going to
use a sanding stick with a 400 grit sandpaper on it and I’m going to finish the top of it
so it will make for a nice smooth edge once we actually set the stone. There we go, smooth, clean, and ready to go.
