How
Was That Made?
Forging........
The
design called for manufacture in 22K gold to match
an existing chain belonging to the client’s spouse.
Since it was an anniversary gift, a heart was chosen
on consultation with the client as the "theme" with
a diamond to "set off" the design. The client picked
the diamond, and the process began. What follows,
is how it’s done…
(Click
on the thumbnail pictures to see the full size image.)
22K
gold grain is melted and poured into a mold in the
shape of a rod, which is then drawn into a rod about
6mm in diameter.
The
gold rod is then annealed (softened) on a fire brick
or pumice surface so that it can be shaped without
exceeding its stress limits.
Since
the design concept called for unusual flowing shapes,
an offset triangular shape was chosen for the cross
section. A steel forging plate is designed and milled
to this cross section.

The
gold rod is then forged (beaten into shape – with
several annealing steps) into the offset triangular
shape. The rod, now triangular in cross section, is
shown laying in the groove in the steel forging plate.
The
rod is cut into two pieces and shaped into the two
halves of the design. To add movement and flow to
the shape, one half is curved with the apex of the
triangular cross section "up" (right hand piece) and
the other with the apex "down" (left hand piece).
The two pieces are then filed and shaped to conform
to the design.
The
two pieces are soldered
together, filed and shaped even further, and then
polished.
A
small "tab" is soldered to the inside curve on the
left-hand side. This will hold the diamond.

The
hole is drilled in the tab to accept the "head"
that holds the diamond. The diamond is shown to
the right, already mounted in a platinum head
to emphasize its color and clarity. The unusual
shaped metal on the left hand side is what will
become the "bail." This is the part that the chain
threads through. It attaches to the small ring
soldered to the top of the heart. |
The
finished piece! After a final polish the pendant
is ready for the customer. Note that the bail is also
in the shape of a heart – a small touch to accent
the individuality of the piece.
