Overview
In selecting a diamond, the rarity, value and beauty is determined by the four
factors mentioned above, called the 4C's: Carat Weight , Color
, Clarity , and Cut (proportions & finish). Today, many consumers are aware
of the 4C's, however, understanding how they determine value is important to
discover what appeals to you in selecting a diamond, and getting the most for
your money.
Carat Weight
Carat weight refers to the size of the diamond. Based on a standard unit of
measure, one carat is divided into 100 points. The term originated from carob
seeds that were used to balance scales in ancient times.

Color
The most desirable diamonds are colorless because the absence of color
enhances the diamond's ability to reflect a rainbow of color. Diamonds are
graded on a scale of D (almost clear white) to N-Z (not sold at Diamonds.com).

Clarity
Diamonds can contain slight imperfections. Often invisible to the naked eye,
these natural birthmarks fall into two categories-inclusions (internal) and
blemishes (external). Fewer inclusions increase the value of the stone.

Cut
Cut gives the diamond its brilliance. Of the four C's, it's the only one
dependent on a human touch. Using precise mathematical formulas, the cutter
transforms a diamond in the rough into a sparkling jewel that reflects and
refracts light. Learn more
Finding the right diamond for you
To understand how the 4C's work together to determine a diamond's rarity and
value, consider this diagram, like a classic balance. For a given PRICE (the
fulcrum), you balance the (Carat Weight) on the left side and (Color, Clarity,
and Cutting) on the right side. To select a larger size for a given price, to
stay in balance, you would choose a less rare quality diamond. To select a
rarer quality diamond, to stay in balance, you would choose a smaller size.
The combination of the 4C's is strictly personal preference. By understanding
this information, you can make the best choice. Realize that Carat Weight
affects the value by about 10-20% per step up or down in size, Color/Clarity by
about 10-15% per/grade, and Cut Quality can affect value by a considerable
amount (25-50%), as it is almost completely controlled by the cutter.
