What
elements should I look for when I purchase a diamond?
|
One
of the most important purchases an individual makes is
that of a diamond. We normally think of an engagement ring.
It is a very emotional and very personal purchase. While
price is a consideration, value is most important. Blind
faith should be left at the door when considering such
an important event. Of all purchases, that of a diamond
should be made by an informed decision. The things to look
for are what we in the jewelry business call the four Cs":
Cut, Clarity, Color and Carat/Weight.
Cut
This refers to the shape or style in
which a gem stone is cut. The depth of
the diamond as a whole, and the depths
of the crown and pavillion all affect the
brilliance of the gem. Through the efforts
of skilled craftsman, the proper cut reflects
the maximum amount of light back to the
eyes.
Most round brilliant cut or fancy-shaped diamonds possess 58 carefully
angled flat surfaces called facets. If the diamond is cut ideally, each
ray of light that strikes the diamond is refracted back out of the top
of the stone, adding fire, brilliance and ultimate beauty to your diamond.

Clarity
This refers to the extent to which
a diamond is free of imperfections, inclusions
and blemishes. Have the jeweler show you
the diamond under a 10X magnification.
Look for anything inside the diamond. A
diamond is like glass; it should be crystal
clear and you should note any small blemish
inside. For example, you may notice inclusions;
black dots or black marks, white lines
or feathers, or any chips around the edge
of the stone. Don't try to grade the diamond
yourself, but, have our sales associate
explain the various grades so that you
may understand where this particular diamond
falls within the grading scale. If you
can not see the inclusions, request that
we point them out.
As a rule of thumb, the easier it is to see the inclusion, the lower
the clarity grade should be. An inclusion in the center of the stone
receives a lower clarity grade than an inclusion of the same size, but
on the side of the diamond. A diamond that is virtually free of inclusions
is judged as flawless. In these diamonds, nothing interferes with the
passage of light nor spoils the beauty. What minute inclusions there
may be make every diamond unique. They do not mar the diamond's beauty
nor do they endanger its durability. Without high magnification, you
may never see these inclusions. However, the fewer there are, the rarer
your diamond will be.

Color
This refers to the color of a diamond when observed
from the top. Colorless or white diamonds are considered
the most valuable, normally. The color grading scale varies
from totally colorless to light color or tinted. The difference
between one grade and the next is very subtle.
Looking at the color is easier than looking at the clarity. To look
at color, ask our sales associate to show you a certified diamond
of the same color and compare the two colors. To do this, you need
a white backdrop and a white light. Have them turn the diamonds on
their backs (top surface or table down). Look for the slightest differences
in body color. Look for yellow, brown or grey. If the colors don't
match exactly, the grading is not accurate.
While the majority of gem quality diamonds appear to be colorless,
others can contain increasing shades of yellow and brown, some of
which are referred to as "champagne diamonds."

Carat Weight
This is the standard unit of weight, in metric terms, used
for denoting the weight of diamonds and gem stones. The abbreviation
to denote a carat is "ct."
One carat is equal to 200 milligrams (one fifth of a gram) and divided
into 100 "points" so that a diamond of 125 points is described
as a one carat and a quarter or 1.25 carats or 250 milligrams. Size
is the most obvious factor in determining the value of a diamond.
However, you now know that two diamonds of equal carat weight can
have very unequal prices depending on their color, clarity, and cuts.
Remember that diamonds of high quality can be found in all size ranges.
There are no two stones exactly alike.
