Many older traditional men’s onyx rings were bezel set with a bezel
set diamond in the center of the onyx. In this case the onyx is
drilled, with a hole smaller than the diamond bezel The bezel is then
is soldered to tubing that will fit threw this hole. The diamond is
set into the bezel, then the tubing on the underside of this bezel is
pushed threw the hole and burnished tight. The larger stone can be
counter sunk to set the bezel down neatly, and often the hole on
underside of the onyx was countersunk slightly, or cross grooved to
allow the burnished metal a better hold to prevent rotation.
We used to solder the bezels onto the tubings, hold each in a
watchmaker’s lathe to set and tighten the diamond, and then assemble
them on thefinnished onyx ring.
Today with access to a laser many variations on this bezel set on to
be= zel set could be immagined, with little risk of damage to heat
