If the back is to be open, the method
I know is to make the bezel and then make an
inner bezel and solder it in, or make the bezel
and solder it to a backplate and saw a small
distance in from the inside of the bezel
and remove that piece.
Both require more time and effort, it is done
with pendants more than rings or bracelets,
there are structural issues, and what is
saved by removing metal is lost by using thicker
metal to compensate for support of the
surface area of the backplate.
Some cabs have beautiful pattern and color
on the back that warrants the use of an
open back. Some people pierce designs in the
One issue with the concept of making things
that can be taken apart, when a cab is set
in a bezel, that would involve prying open
the bezel, and that usually causes more damage
to the bezel than any benefit gained.
Riveting could be used, that becomes an
issue of design and esthetics.
There are settings that are made for

and negatives to that method.
Traditional Navajo silver pieces with turquoise
are usually very heavy substantial pieces,
durable pieces that can be passed down
through generations, no repair or
modifications needed for the life of the piece.
There is also a difference which technique is
used, fabricating or casting.
Some parts are cast and used for fabrication,
they are soldered (brazed) together and it
is not practical to engineer the pieces to be
There are pieces from the old days, these
pieces were fabricated and the last part was
soldered with lead solder to be taken part
I hope this give you an insight into the
methods used to create jewelry and the
long history of traditional manufacture and
construction of jewelry.
I would like to hear from jewelry makers
on this forum who do incorporate the ability
for their pieces to be altered.
