In learning about diamonds there are four items that when combined give the appearance and value
of every diamond. These are the four "C's".
The four C's are Cut, Clarity, Carat Weight, and Color. (Follow this link to more information.)
===========================================================================
Diamonds Definitions:
- Brilliance: Total amount of white light returned to the eye from a gem marerial as a result
of
internal and external reflections
- Carat: Unit of weight for gems. Equal to 200 milligrams

- Clean: Free from noticeable flaws
-
- Crown: The part of the gemstone above the girdle
-
- Facet: One of the plane, polished surfaces placed upon a gemstone, fashioned as brilliant cut, step cut, etc.
-
- Feather: Almost any flaw inside a stone
-
- Flaw: An inclusion of another substance, cleavage or fracture
-
- Fracture: A break or chip in any direction

- Inclusion: Any optically detectable irregularity of a gem material

The difference between a Diamond
Certificate and an Appraisal:
A Diamond Certificate is
a document that describes the physical characteristics of a loose
Diamond and is issued by a Gemological Laboratory.
A Diamond Certificate issues a "grade"
indicating the physical properties
of the Diamond "at the time of evaluation",
and remains valid as long as the Diamond is not chipped or otherwise altered.
An appraisal can be
performed on a loose Diamond, a mounted stone, or jewelry. If the
stone is not loose, the physical properties are estimated using
various estimation techniques. Most importantly, an appraisal
indicates the Dollar Value of the piece under consideration.
Obviously, the Dollar Value can easily change considerably over a
relatively short period of time. Appraisals are most often used for
insurance purposes.
===========================================================================
Diamond Enhancement:
Diamond clarity can be improved, but not all enhancement techniques are permanent.
The two most popular treatments are:
Laser Treatments:
A laser is used to remove some types of inclusions.
An experienced jeweler can usually see the trail left by the laser. Laser treatments are permanent.
Fracture Filling:
Tiny cracks in a diamond are filled with a colorless substance.
Fracture filling is not considered permanent. In fact, many times when a ring is cleaned in an ultrasonic bath
the flaw becomes very apparent.
Treatments allow us to own a diamond that appears to be of a higher clarity than it truly is.
Treated diamonds should cost less, so it's important to do business with a jeweler you trust, one who evaluates and discloses any type of enhancement that's been performed. Return to Pioneer and Jewelry Home Page
