Once you have established those 4C characteristics that are most important to you,
a jeweler can then begin to show you various options with quoted prices.

THE DIAMOND QUALITY PYRAMID
A Tool to Help Understand a Diamond's Value

CARAT
Refers to the weight of a diamond.

Carat is often confused with size even though it is actually a measure of weight.
One carat is equivalent to 200 milligrams. One carat can also be divided into
100 “points.” A .75 carat diamond is the same as a 75-points or 3/4 carat diamond.

A 1-carat diamond costs exactly twice the price of a half-carat diamond, right?
Wrong. Since larger diamonds are found less frequently in nature,
which places them at the rarest level of the Diamond Quality Pyramid,
a 1-carat diamond will cost more than twice a 1/2-carat diamond
(assuming color, clarity and cut remain constant).

CLARITY
Refers to the presence of inclusions in a diamond.

Inclusions are natural identifying characteristics such as minerals or fractures,
appearing while diamonds are formed in the earth. They may look like tiny crystals, clouds or feathers.

To view inclusions, jewelers use a magnifying loop. This tool allows jewelers
to see a diamond at 10x its actual size so that inclusions are easier to see.
The position of inclusions can affect the value of a diamond.
There are very few flawless diamonds found in nature, thus these diamonds are much more valuable.

Inclusions are ranked on a scale of perfection, known as clarity,
which was established by the Gemological Institute of America (GIA).
The clarity scale, ranging from F (Flawless) to Included (I),
is based on the visibility of inclusions at a magnification of 10x.

Some inclusions can be hidden by a mounting, thus having little effect on
the beauty of a diamond. An inclusion in the middle or top of a diamond
could impact the dispersion of light, sometimes making the diamond less brilliant.

The greater a diamond's clarity, the more brilliant, valuable and rare it is—
and the higher it is on the Diamond Quality Pyramid.

COLOR
Refers to the degree to which a diamond is colorless.

Diamonds range in color from icy winter whites to warm summer whites.
Diamonds are graded on a color scale established by the
Gemological Institute of America (GIA) which ranges from D (colorless) to Z.

Warmer colored diamonds (K–Z) are particularly desirable when
set in yellow gold. Icy winter whites (D–J) look stunning set in white gold or platinum.

Color differences are very subtle and it is very difficult
to see the difference between, say, an E and an F.
Therefore, colors are graded under controlled lighting
conditions and are compared to a master set for accuracy.

Truly colorless stones, graded D, treasured for their rarity, are highest on the
Diamond Quality Pyramid. Color, however, ultimately comes down to personal taste.
Ask a jeweler to show you a variety of color grades next to one another to help you determine your color preference.

CUT
Refers to the angles and proportions of a diamond.

Based on scientific formulas, a well-cut diamond will internally reflect light from
one mirror-like facet to another and disperse and reflect it through the top of the stone.
This results in a display of brilliance and fire, thereby placing well-cut diamonds higher
on the Diamond Quality Pyramid than deep or shallow-cut diamonds.
Diamonds that are cut too deep or too shallow lose or leak light through the
side or bottom, resulting in less brilliance and ultimately, value.

Cut also refers to shape—round, square, pear, or heart for example.
Since a round diamond is symmetrical and capable of reflecting nearly
all the light that enters, it is the most brilliant of all diamond shapes and
follows specific proportional guidelines. Ask a jeweler to find out more about these guidelines.

None-round shapes, also known as “fancy shapes,” will have their own guidelines to be considered well-cut.
