Jewelry Glossary
|
This setting surrounds a larger center stone with several smaller
stones. It is designed to create a beautiful larger ring from many
smaller stones.
|
|
Oversized ring with precious or semi-precious stones.
|
|
Diamonds are graded on a color scale established by the Gemological
Institute of America (GIA). Fancy colors refer to diamonds with hues
like pink, blue, green, yellow, and very rarely red. Fancy colors are
not included in this color scale and are considered extremely rare.
|
|
A human-made gem with nearly the same optical, physical and chemical properties of a natural gemstone.
|
|
This is the upper portion or the top of a diamond.
|
|
Round or oval bracelet with clasp and hinge.
|
|
The bottom point of the diamond. It may be polished in some stones.
Sometimes, a cutter may choose to make the culet a surface instead of a
point.
|
|
A chain with oval links that are twisted to lie flat.
|
|
A mixed-cut diamond shaped like a square pillow.
|
|
Cut refers to the angles and proportions a skilled craftsman creates in
transforming a rough diamond into a polished diamond. Based on
scientific formulas, a well-cut diamond will internally reflect light
from one mirror-like facet to another and, disperse and reflect it
through the top of the stone. This results in a display of brilliance
and fire. Diamonds that are cut too deep or too shallow lose or leak
light through the side or bottom, resulting in less brilliance, and
ultimately value.
|
|
Cutting styles are different than diamond shapes. The simplest and most
common way to explain cutting style is to categorize it into the
following three basic types: Step-cut, Brilliant-cut and Mixed-cut.
|
|
When a diamond is cut too deep, it will lose or leak light through the
side or bottom. This results in less brilliance and value.
|
|
A diamond is the hardest known natural substance. It is crystallized
carbon. Diamonds are mined in their rough form and then, cut and
polished to reveal their brilliance.
|
|
There are many recognized gemological laboratories that can grade your
diamond for a fee. The most well known is the GIA, Gemological
Institute of America.
|
|
When light enters a diamond it reflects off the facets and the angles
cut into the stone. This distribution of light is known as dispersion,
or the display of the spectral colors.
|
|
An accessory designed to decorate a stud earring.
|
|
The process of covering a base metal with a thin film of gold.
|
|
A rectangular or square-shaped cut-cornered diamond. A form of step
cutting, this cut is favored for diamonds and emeralds, as well as many
other stones, when the principle purpose is to enhance color rather
than brilliancy. It is also sometimes used to emphasize the absence of
color in diamonds.
|
|
In its simplest terms, all enamel is produced by fusing colored
powdered glass to metal to produce a vitreous or glass-like decorative
surface.
|
|
Any flat polished surface of a diamond or gemstone. This style of
cutting gives the stone many small faces at varying angles to one
another. The placement, angle and shape of each facet are carefully
planned and executed to show the stone's inherent beauty, fire, color,
and brilliance to the fullest advantage.
|
|
A diamond cut other than round: such as baguette, emerald, pear, marquise, square, oval, heart, etc.
|
|
A type of inclusion or flaw within a diamond. It is described often as a small crack or fissure.
|
|
A chain with long and round links that are not uniform in size.
|
|
Delicate, thread-like decoration.
|
|
Describes the exterior of the diamond. If a diamond is well polished, it has a very good finish.
|
|
Often a term used instead of "dispersion," it is the variety and
intensity of rainbow colors seen when light is reflected from a diamond.
|
|
Like the Gypsy setting, this setting has a band that is one continuous
piece that gets thicker at the top. A flat-top setting grows broader at
the top so that a faceted stone can be inserted into the ring at the
broadest part. The stone is held in place by metal chips attached at
the stone's girdle.
|
|
When exposed to ultraviolet light, a diamond may exhibit a more
whitish, yellowish or bluish tint, which may imply that the diamond has
a property called fluorescence. The untrained eye can rarely see the
effects of fluorescence. Diamond grading reports often state whether a
diamond has fluorescent properties.
|
|
A short chain with a decorative seal or other device attached to the end.
|
|
A process that injects a substance into a diamond to hide inclusions.
|
|
The outer edge of a cut stone, the dividing line between the crown and
the pavilion. Sometimes the girdle is polished and sometimes it is
unpolished. Ideally the width of the girdle should be even and
proportional to the cut of the stone.
|
|
These can be considered internal flaws, and can often be seen only by
rotating the diamond very slowly. They can appear and disappear almost
instantaneously. They appear as small lines or planes within the
diamond.
