As gemstones in their natural state
are rather shapeless, their beauty is greatly enhanced by cutting them into geometrical
shapes, most of which provide numerous facets to reflect light that enters the stone
back out to the eye. The efficiency of the stone in reflecting this light
is based in large part on the shape of the facets and the accuracy of their
A pendant made up of two hinged pieces, which may be used to hold photographs, a
lock of hair, or some other small memento. At ViridianGold.com, all of our
lockets are felt lined, provided with clear photo protectors, and are suitable for
at least two photographs. Some lockets have a third hinged piece between the
front and back pieces which will hold two additional photographs. Lockets
are often engraved with initials or a short phrase--many lockets provide a space
for initials on the front. At ViridianGold.com, you will find
in an array of styles.
Not all jewelry metal
is finished the same way. There are several types of finishes which are applied
to the gold and platinum used in fine jewelry--here are a few which appear in jewelry
carried by ViridianGold.com:
A process by which the natural surface oxidation of some types of metal(such
as aluminum and titanium), is increased by electrical current, resulting in
a hard coating on the metal. The coating can also be color-dyed.
Once the surface is oxidized in this way, it is resistant to further oxidation.
Blacking, Antiquing: Some gold diamond rings have a black enamel applied
in recessed areas of the ring design. Because the gold to which it is
applied is naturally resistant to impurities, this enamel will wear off over
time. Therefore, the same care should be followed as for all diamond rings:
they should be removed for dish washing, swimming, handling chemicals, manual
labor and other activities which could damage the ring. Nail polish remover,
lighter fluid, Lava® soap and other common household solutions can damage or
remove the finish, also. Any jeweler will be able to refresh the black
enamel when you take your rings for routine cleaning.
A form of matte finish, bead blast is performed with a stream of high speed
air, mixed with fine particles (such as fine sand), which is directed at the
surface of the jewelry piece.
Similar to Matte finish, a brushed finish is composed of tiny striations,
or scratches, in the finish as made by a metal brush. If the striations
are very fine, the finish is similar to matte. The terms are often used
Cloisonné: A type
of finish in which areas of metal are separated by thin, metal strips which
outline the design. The areas are then filled with colored enamel and fired
at high temperatures.
cut: The surface of the metal is cut into highly polished facets
which reflect light at different angles, creating a sparkling diamond-like effect.
Die Struck: A die is a hard-steel tool
upon which an image has been formed. It is machine-pressed with great
force ("struck") onto a precious metal blank, creating a sharp, dimensional
design which is polished and further formed into the jewelry piece.
The design or text formed in the metal is raised above its surface,
the opposite of engraving.
The process of fusing colored glass or other very hard compounds onto the metal
to provide color that is not usually found in alloys of the base metal.
After covering the metal everywhere except where the design or text is desired,
a strong acid is applied to the piece which removes the unprotected sections
of the metal, forming the desired design.
Epoxy resin: An epoxide
polymer that cures when mixed with a hardener, creating a synthetic resin.
Epoxy resin is very durable, thus it is often used in jewelry inlays.
Etched: The design
or text is cut into the metal, thus being formed below its surface--the opposite
Intricate patterns of open work in the metal which are formed by fused gold
wire or by cutting through the metal.
Florentine: A cross-hatched engraved
design, more coarse than a brushed or matte finish
Gold Tone or Silver Tone:
Indicates that a non-precious metal is coated or plated to resemble gold or
silver. Often used in metal jewelry and keepsake boxes.
(pronounced ghi-LOWSH) An intricate interlaced pattern that is engraved by an
engine-turned lathe. When a translucent enamel is applied, as in a Faberge
Egg, the engraving can be seen through the enamel.
Random indentations in the metal either formed by the mold in which the piece
was formed, or by actual hammering.
All jewelry is polished to some extent in order to remove the rough
surfaces which are formed in the manufacturing process. This is a labor-intensive
step and is often compromised in lower-quality jewelry, especially on the underside
of the crown of rings and the backs of pins and brooches. Highly polished
metal has a mirror-like finish.
A non-reflective surface--the metal has been polished, but not to a mirror-like
finish. The effect is often achieved by abrading the surface with fine
materials after polishing. Similar to Brushed finish, though not
as coarse--the terms are often used interchangeably.
A sheet of woven fine, precious metal or steel wire.
The metal is formed with a texture resembling dentil moulding or a line of tiny
beads, depending on the style, which outlines a design detail or border.
Oxidized: The metal
surface, typically silver, is caused to combine with oxygen to create a darkening
of the metal--the same as tarnishing, except it is limited to only the desired
area to be darkened.
The metal has a softer shine than a highly polished metal, but not as dull as
a matte finish.
The surface is etched into a frosted appearance using a powerful laser beam.
