The price of a diamond varies depending on the four C's:
cut, color, clarity and carat weight.
Cut: When a diamond is a cut to great 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.

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.
are natural stones and virtually they all have some type of inclusions,
or flaws. The difference in the clarity of stones depends on whether
you can see the inclusions with the naked eye or only when magnified
using a microscope .The location of the flaws is also important.
Clarity is graded on a scale with flawless (F) or internal flawless
(IF) at the top, followed by VVS1 and VVS2 (very very slight inclusions),
VS1 and VS2 (very slight inclusions), SI1 and SI2 (slight inclusions),
and I1, I2 and I3, which means inclusions are visible to the naked
eye. Diamonds any lower on the clarity scale are not considered
gemstones and used mainly for industrial purposes.
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.
