THE
4 C's OF DIAMONDS
The 4 C's of diamonds Color,
Cut, Clarity,
and Carat
Weight represent a set of jewelry industry standards
for determining grade, quality and value of diamonds.
Diamonds are available in almost any color. However,
most consumers request a diamond to be as colorless as possible. An
absolute colorless diamond is rare and very expensive. Most diamonds
have traces of yellow, brown or gray, which limits light reflection.
The less color in a diamond and the more light it reflects will produce
a better grade of color. Diamonds are graded by color starting with
"D" and continuing through the alphabet. Grades are as follows:

BEST
VALUE IN COLOR GRADE
D & E - colorless (Has no color and are treasured for its rarity
and value.)
F
- (Begins showing slight color but still considered white.)
TOP
QUALITY WITH NO NOTICEABLE COLOR
G,
H, I, & J - near colorless with a slight yellow cast (Relatively
high color and lower price point.)
LOWER
QUALITY
K,
L, & M - faint yellow to brown in color
N,
O, P, Q, R - very light yellow color (Lower priced; may show color when
mounted.)
S,
T, U, V, & W - light yellow (Less rare and less valuable. Shows
substantial yellow when mounted or not mounted.)
X,
Y, & Z - ("Fancy" diamonds, which may include shades of
red, pink, blue, green or yellow, are highly regarded and rare.)
Fan
Designs offers a variety of certified and non-certified diamonds. Certifications
are performed by the Gemological Institute of America (G.I.A.) or the
European Gemological Laboratory (E.G.L.). In addition, a retail appraisal
is furnished with all loose diamond purchases.
CUT means the geometric proportions of a diamond as opposed to shape.
The cut determines the amount of sparkle in a stone. Diamonds are cut
in the following shapes:
|
|
|
|
|
|
|
|
|
Round
Brilliant |
Emerald |
Heart |
Marquise |
Oval |
Pear |
Princess |
Regardless
of its shape, diamonds get their brilliance by the cut and polish of
facets (the flat surfaces of a diamond). A well-cut diamond allows the
maximum amount of light to reflect from one facet to another releasing
fire, sparkle and brilliance. When a stone is cut too shallow or too
deep, the light entering through the top refracts through the bottom
or sides of the diamond and does not allow the beauty of the stone to
be realized. Therefore, poorly cut diamonds have less brilliance or
fire and are less valuable than well-cut diamonds.
There are four types of cut:
- Ideal Cut
Provides the maximum amount of reflected light. A brilliant or round
cut diamond is the only diamond that may be graded as "ideal cut".
-
Very Good Cut
Reflects back nearly all the light that enters the diamond. This is
the highest cut grade available in any fancy shape diamond (oval, princess
or emerald.)
-
Fair Cut
The weight of the diamond is enhanced with a fair cut stone. However,
the stone will loose its brilliance and fire with as little as 40 percent
being reflected.
-
Poor Cut
This is a cloudy, lifeless looking diamond and is not recommended for
fine jewelry.

The CLARITY of a diamond is determined by two types of flaws: internal
and external. These flaws, which are natural birthmarks, may also be
called "inclusions". External inclusions are impurities on
the surface of the diamond. Internal flaws are located in the interior
of the stone. These natural imperfections affect a diamond's value.
Large flaws may interfere with light reflecting through the diamond
and that means less brilliance and sparkle. Therefore a diamond having
large flaws is less valuable. Inclusions may include:
-
Black or dark spots called "carbon"
- Clouds, which are inclusions that lower the transparency of a diamond
- Fractures, sometimes called "feathers", cause a breakdown
in the chemical structure of a diamond.

The
amount and location of inclusions in a diamond determines the grade
of clarity. These grades are as follows:
FL
- Flawless (no internal or external inclusions - rare)
IF
- Internally Flawless (no internal flaws - extremely rare)
VVS-1,
VVS-2 - Very Very Slightly Included (difficult to see with 10-power
magnification)
VS-1,
VS-2 - Very Slightly Included (difficult to see with 10- power magnification)
SI-1,
SI-2 - Slightly Included (easy to see inclusions with 10- power magnification)
I-1,
I-2, I-3 - Included (inclusions may be seen without 10- power magnification)

A diamond's size is measured in CARAT WEIGHT. Each carat is equal to
100 points (i.e., a .50 carat diamond is the same as a 50 point or 1/2
carat diamond).
The
price of a diamond is determined by its COLOR, CUT, CLARITY and CARAT
WEIGHT. To determine a price for a diamond, multiply the carat weight
by the price per carat.
WEIGHT
X PRICE PER CARAT = TOTAL PRICE FOR A DIAMOND
CARING
FOR YOUR DIAMOND
There are several ways to care for your diamond. However, we recommend
the following:
THE
DETERGENT SOAK
Prepare a small bowl of warm suds with any mild liquid detergent. Brush
diamond jewelry gently with a toothbrush while soaking in suds. Transfer
to a wire strainer and rinse under warm running water. Pat dry with
a soft, lint free cloth.
THE
COLD WATER SOAK
Make a half and half solution of cold water and household ammonia in
a cup or bowl. Soak your diamond jewelry for approximately 30 minutes.
Lift out and brush gently with a small brush. Dip jewelry once more
in solution and drain on paper towel. No rinse is necessary.
YEARLY
MAINTENANCE
We advise you to take your diamond jewelry to a qualified and reputable
jeweler for a check up at least once a year. Your jeweler will check
for signs of wear and tear as well as test for loose stones. You may
also want to request cleaning and polishing at this time.
AVOID
THE FOLLOWING WHEN CARING FOR YOUR DIAMOND
Do not let your diamond come in contact with chlorine bleach or other
household cleaning products. Bleach and other products may damage the
ring mounting.
Avoid
wearing your diamond when doing rough work or washing dishes. Even though
a diamond is durable, it may become chipped along its grain when subjected
to a hard blow.
Diamonds
are durable but should not be placed in a container with other jewelry
since the stone may scratch or damage other fine jewelry.
