About Diamonds (Diamond FAQ)
|The Four most popular factors used to|
measure diamond quality are: Color, Carat,
Clarity and Cut. Topics to discuss are Diamond
Color Clarity Grade, Diamond Grades Quality Information & Diamond Grade Scale.

|Color: (The color used in this diagram is for presentation purposes and is not actual
experts name color as the number one consideration in choosing a diamond. A
diamond's color is graded on an alphabetical scale from D-Z, with D being absolutely
colorless and Z being light yellow. Beyond "Z",
a diamond is considered to be an exotic or "Fancy" color.
DIAMOND COLOR SCALE
Since color differences can be so subtle, they are impossible
to determine by the untrained eye. To grade a diamond, gemologists often
place it on a white background next to another diamond that has been
If all other factors are equal, the less color in a diamond
or the higher color rating, the more valuable a diamond becomes. Likewise,
as the amount of color increases, the price of a diamond decreases (though
this does not necessarily reduce the beauty of a diamond.)
All diamonds have identifying characteristics, but most are invisible to
the naked eye. To view a diamond, experts use a 10x magnifying loupe which
allows them to see the appearance of tiny crystals, feathers or clouds. These
natural phenomena are called inclusions.There are five categories in class
that anyone interested in purchasing a diamond should be aware of when grading
DIAMOND CLARITY SCALE
Very Very Slightly
FL (Flawless) - IF (Internally Flawless)
Flawless Diamonds reveal no flaws on the surface or internally are the rarest
and most beautiful gems.
Internally Flawless Diamonds reveal no inclusions and only insignificant
blemishes on the surface under 10x magnification.
VVS1 - VVS2 (Very, Very Slightly Included)
Very difficult to see inclusions under 10x magnification. These are excellent
VS1 - VS2 (Very Slightly Included)
Only looking through a 10X loupe can pinpoint the inclusions in this category
and are nearly impossible to see with the naked eye. These are less expensive
than the VVS1 or VVS2 grades.
SI1 - SI3 (Slightly Included)
Diamonds with inclusions easily identified under 10x magnification. Finding
flaws in this category with the naked eye is difficult. The gems in this category
maintain their integrity, depending on the location of the inclusions.
I1 - I3 (Included)
Diamonds with inclusions which may or may not be easily seen by the naked eye.
The flaws on the stones in this category will have some effect on the brilliance
of your diamond.
Carat: (This diagram is for
presentation purposes and is not to scale)
Carat is often confused
with size even though it is a measure of weight. The cut of a diamond
can make it appear larger or smaller than its actual weight.
One carat is the equivalent of 200 milligrams. One carat can be divided
into 100 "points". A .75 carat diamond is the same as 75 points
or a 3/4 carat diamond. Since larger diamonds are rarer than smaller diamonds,
the value rises exponentially with carat weight.
Cut actually refers to two aspects of
a diamond. The first is its shape (round, marquise, etc) the second is
how well the cutting has been executed.
A diamond's cut will most certainly influence its fire (the lovely rainbow
colors that flash from within) and brilliance (the liveliness and sparkle),
as well as its perceived size and even, to some degree its apparent color.
Different cuts reflect light in different
angles. A diamond must be cut in a geometrically precise manner to maximize
