The Price of Quality
The world of fine jewelry is not a simple one. There
are many factors involved in determining jewelry value and
the values can vary greatly within any given size of diamond
or other gemstone. For example, a 1/2 carat diamond may vary
from another by hundreds or even thousands of dollars because
of the quality of cutting, color and clarity. Colored gemstones
also vary greatly in quality and price.
Two
other factors involved in jewelry pricing are design and
workmanship. You would expect to pay more for a finely-made
piece than for one poorly made. You must also expect to pay more
for a hand-made or custom-designed item than for a mass-produced
design.
The Look of Quality
The workmanship of a piece is important for both its beauty
and your security. Well-balanced and interesting design and
smooth polishing and finishing characterize the well-made
item. Stones must be properly set with prongs that are secure
yet small and uniform. Safety catches, pin stems, clips and
earring backings must work well. Chain links must be firmly
closed or soldered.
Since
jewelry is not all the same, you are safest in patronizing a
retail jeweler that is well established and has highly trained
associates on staff. A skilled jeweler or gemologist understands
the safety factors necessary to protect you, the customer. Not
only can you rely on such a jeweler for securely made items, but
you can also trust in his or her judgment on the nature and
quality of gems and metals used in a jewelry piece.
The Artistic Process
The making of fine jewelry is truly an art from concept
to execution of the design. After the initial sketches and
models are made, one of the following processes is used to
create an enduring piece of jewelry who's beauty will give
continuous pleasure.
Hand
Wrought
This is
the term used for the fashioning of an item of jewelry entirely
by hand, including melting the metal in a crucible, hammering
and bending it to the desired shape, boring and sawing the
necessary holes, using special tools to engrave texture on the
metal, welding and soldering parts together, and burnishing and
polishing the metal.
Cast
For
most fine jewelry pieces that are to be made in quantity, the lost
wax, or centrifugal casting, method is employed. Here, the
model is carefully sculptured in wax, then placed in a flask
into which plaster is poured. The plaster investment is placed
in a vacuum to remove bubbles, then allowed to harden. The wax
is burned out in an oven (lost), leaving behind a cavity which
duplicates the original model in all its detail. The flask is
then placed in a centrifugal casting machine which throws molten
metal into the cavity. If many castings are desired from one
model, the first casting is carefully finished, and a flexible
rubber mold is made from it. Then, as many wax replicas as
desired are made in the rubber mold and reproduced in metal like
the original. Large molds may be made by placing many wax
replicas together in the same flask and casting them at one
time. A hundred or more pieces may be made by this process,
allowing for large production of a quality product.
Die
Struck
Finely
machined dies are made to the desired design and shape from a
piece of unhardened steel to form a hub. The hub is
then hardened and forced into another piece of unhardened steel
to make a sunken die. Bar metal is shaped between the
two dies by tremendous pressure or a drop hammer. This type of
manufacture is used for fine quality, mass-produced items such
as basic ring mountings and standard designs.
Popular
Settings
-
Prong
- Six
and four-prong settings are the most popular for ladies'
rings. A tiffany setting is a six-prong setting using long,
slender prongs. (The term is sometimes used to describe
four-prong settings.)
-
Bezel
-
The stone is set within a wall of metal. This is usually
used for cabochon-cut (dome-shaped) stones.
-
Gypsy
- The metal contains a groove to hold the lower
portion of the stone.
-
Bead
- The stone is dropped into the setting and held
securely by added beads of metal.
-
Pavé
- This is a form of bead set in which many very
small diamonds are set closely together, preferable in white
gold or platinum, to give the impression of a continuous
diamond surface.
The Well-Made Jewelry Item
Classic examples of beautiful settings that enhance
gemstones in rings are bezel set, pavé set, and a combination
of prong and head set.
-
Rings
Mountings
must be sturdy enough for wear yet not clumsy looking.
Settings for stones must be smoothly drilled, round, with
the underside of the ring shank polished to give a finished
look. Prongs must be pushed up close to the stone to hold it
securely and must be smoothly rounded. Stones must be set
flat, not tilted.
-
Necklaces
Holes
in beads must be smoothly drilled and accurately centered.
Links must be firmly closed and of good quality metal to
withstand wear. Clasps should be relatively easy to open and
close, yet secure. The best have some type of safety
attachment to prevent loss.
-
Earrings
Both
earrings must match closely in design, be neatly
constructed, well balanced and comfortable to wear. Earring
findings - screw back, clip, pierced ear wires, threaded
post, or friction back - must be sturdy and in good working
order.
-
Bracelets
Joints
must be arranged so they do not rub or interfere with
stones. Hinged bracelets must be very well machined so as to
function smoothly. Catches and clasps also must be well made
and strong enough to hold up under usage.
Precautionary
Measures
Settings
must be periodically checked by a jeweler for security. Clasps
must be repaired or replaced at the first sign of trouble.
Pearls must be restrung occasionally to avoid weakened string.
An
Ancient Art
In earliest Egyptian and Greco-Roman eras, the jeweler's
art was a revered vocation. Modern jewelers, craftsmen and
manufacturers continue the same fine traditions. The personal
joy and pride derived from the possession of jeweled works
of art have also been carried down through the generations.
