Choosing
a diamond can be an exciting and sometimes confusing process. ARK
Jewelers can help in this important decision.
THE
DIAMOND'S VALUE
The
three qualifications of a gemstone are durability, rarity and beauty;
and a diamond is the most prized of all gemstones. Diamonds are
durable; they are the hardest gemstone known to man. Only a diamond
can scratch another diamond. On the Moh's scale of hardness of
one to ten, the diamond is a ten. A diamond is rare, given that
there are only a few diamond producing areas in the world, that
diamonds are difficult to find, and that diamonds are expensive
to extract from the ground. A diamond is an object of beauty. Even
in the rough, the diamond crystal is beautiful and its beauty is
only enhanced upon cutting and polishing. Just like everything
in nature, each diamond is unique and no two are alike. The diamond's
characteristics (the clarity, color, cut and carat) give each diamond
its own identity. ARK Jewelers utilizes the Gemological Institute
of America's diamond grading system. The GIA is a scientific and
educational institution for diamond resource information, and its
grading system is recognized worldwide.
THE
DIAMOND'S QUALITY-The Five C's
Cut
The cut of the diamond is perhaps the most important of the C's
because the quality of the cut is what gives the diamond its brilliance
and beauty and strongly contributes to the diamond's value. The
cut of the diamond is fashioned by human hands and is the only
C that is not determined in nature. Diamond cutters cut and polish
diamond rough by hand into objects of beauty. It requires a master
stone cutter to fashion an ideally cut diamond. Facets are the
tiny planes on the diamond's surface, which give it sparkle and
fire. The manner in which the facets are angled to each other and
the diamond's proportions determine the brilliance, dispersion
and scintillation, or its light refraction, display of spectral
colors and their movement, respectively.
The
cut can contribute up to 40% of the diamond's price. Therefore,
the better cut diamonds will demand a higher value and price.
Color
Color
is the inherent body tone color in a diamond when viewed table
down through the pavilion with a cool white light and white background.
The less color the diamond has, the more rare it is and, therefore,
the more valuable.
The
color scale starts at D and follows the alphabet down to Z. D,
E and F are in the "colorless" range, and are the most rare color
ratings. G through I are labeled "near colorless"; these stones
will face up colorless when mounted. Color grades K through M are
faint yellow. N through R color graded diamonds are very light
yellow. Diamonds S through Z have an obvious yellow tint. A diamond
with more color than Z would be considered a fancy yellow diamond.
Other fancy colors can occur, such as pink, blue, green, red, purple
and orange.

Clarity
The
third C of diamond grading is clarity, which refers to the diamond's
natural characteristics, or inclusions, and blemishes. Inclusions
are internal while blemishes occur on the surface of the diamond.
The vast majority of diamonds have inclusions and blemishes. The
size, number, position, nature and color or relief of these characteristics
determine the clarity grade. Diamonds are graded under standard
ten power magnification. It is desirable to have a diamond that
is as free as possible from these characteristics; because fewer
inclusions and blemishes allow more light to be reflected. A flawless
diamond is the most rare and the most valuable.

Carat
The
Fourth C of diamond grading is carat. This refers to the weight
of the diamond. The term carat comes from the carob bean, weighing
approximately 0.2 gram, which was used to weigh diamonds in the
early days. The standard diamond weight measure is 1.00 carat.
= 0.2 gram. Like pennies to a dollar, carat weight is broken down
into points. Thus, 1.00 carat = 100 points.
Certification
At
ARK Jewelers, we also advise our customers about certification.
The certification of a diamond is an evaluation of cut, color,
clarity and carat information recorded in a grading report, performed
by an independent laboratory and signed by a graduate gemologist.
The independent laboratory is contracted to only grade the diamond.
The laboratory is completely unbiased to the diamond's grading,
as it is not connected to the buying, selling or pricing of the
diamond. The certification is recognized as an authoritative reference
to the diamond's grading. All of ARK Jewelers' fine diamonds are
certified. |
