The Four C's
The price of a diamond varies depending on the four C's: cut, color,
clarity and carat weight.
When a diamond is a cut
to ideal proportions, light will reflect from one mirror like facet
to another and disperse through the top of the stone, resulting
in brilliant display. Diamonds that are cut too shallow or deep
will lose light through the sides and bottom of the stone and may
have dark center.

Color: Diamond color is graded on a scale from D to Z.
Truly colorless stones are rated D and are extremely rare. Value starts
to drop significantly at grades L, M and N, and then increases again
at the very end of the spectrum, which includes fancy
diamonds that can be yellow, blue, pink or other color.
Clarity: Virtually all diamonds have some type of inclusions,
or flaws. The difference in the clarity of stones depends on the naked
eye or only when magnified 10 times under a microscope .The location
of the flaws also are important. Clarity is a graded on a scale with
flawless (F) or internal flawless (IF) at the top, followed by VVS1
and VVS2 (very slight inclusions), SI1 and SI2 (very slight inclusions),
and I1, I2 and I3, which means inclusions are visible to the naked eye.
The smaller the number, the fewer the inclusions. Diamonds any lower
on the clarity scale are not considered gemstones and used mainly for
Carat weight: The carat is a unit of weight derived thousands
of years ago from the relatively constant weight of the carob seed.
Carats are divided into 100 points. The carat weight is the size of
the stone and has no bearing on the color and clarity of a diamond.
