Jewelry and Watches
From archaeological excavations, we have learned that jewels have been favored by humans since as early as 20,000 B.C. Materials such as shells, ivory and wood were crafted into imaginative ornamentation.
Symbolic purposes of jewelry:

commemorate the deaths of
aristocracy.
Jewelry is functional as well as an
adornment

Production Techniques
After the design has been conceived
and sketched, it is ready to be
transformed into a piece of jewelry.
Fusing – liquefying the metals and
joining them without the use of another
metal.
Soldering – requires the use of a
separate metal that has a lower
melting point to join metallic parts.
Drawing – jewelers make thick
wires into thinner gauges.
Casting – this process involves
making a cast or mold into which
molten metals are forced.
Stone Settings
Tiffany setting – is typically used
for stones that are to prominently
displayed without the intrusion of too
much metal.
•4-6 prongs in U-shaped openings
are used to hold a stone in place.https://youtu.be/3HOVVXdU_w0
Illusion setting – is used to give
the impression that the stone it
holds is larger than its actual size.
It uses a metal border that features
a design that surrounds the prongs.
This patterned design creates the
illusion of a larger stone.
Cluster setting – generally six
stones used to surround one in the
center.
Pave setting – has extensive blank
areas that are tooled into little bead-
like surfaces that surround a number of
small stones (paved with stones) – gives
the surface a brilliant effect.
Channel setting – the stones are
lined up next to each other with no
metal between them and set into
grooves or channels.
Bezel setting – holds a stone in
place by a rim of metal that goes
around its entire perimeter.
Sometimes it is called a flush
setting.
Buttercup head setting – has six
prongs that rise from a scalloped base
and resemble a flower bud. It is used
for pendants and earrings
Paste settings – used for
inexpensive jewelry. The stones
are glued into the setting.

use, watches achieved acceptance
in the mid 1800’s
Mechanical watches – dates
back several hundred years.
•Mainspring barrel used
•Loud ticks
For precision, use jeweled
movements. (eliminates the noise)
17 jewel movement – uses 17 jewels
as friction points on watches.
Electronic – first electronic watch went
into production in 1956 – power cell
used.
Advantages
•Elimination of ticking sound
• Keeps better time than jewel movements
• Fewer parts
Digital watches – a timepiece that uses
solid-state components instead of
moving parts and displays the actual
time whenever a button is pushed
Quartz Watch- a timepiece that
has accuracy 10 times greater than
that of the conventional watch.
