Information about
the 4 C 's to Diamonds - The Carat Weight
What does the Carat
Weight of a diamond, an important category in the 4C 's, mean? A Carat is a standard unit of weight for
diamonds. Carat weights are also expressed as "points" with a one carat
diamond equalling 100 points. The term 'carat' is
often misunderstood to mean the size of a diamond. The size of a diamond
relates to the dimensions of diamonds in terms of length, width and
height. As the carat weight is a unit
of measure, and not size, two diamonds both weighing 1 carat may appear
to be different sizes! The final size of a 1 carat diamond depends on
how it is cut. Some diamonds will have extra weight on the
bottom part, or pavilion and therefore appear smaller. A well cut
diamond will sometimes appear larger than many diamonds of a heavier
carat
weight.
Information about
the 4 C 's to Diamonds - The Cut
The Cut of a
diamond, an important category in the 4C 's, refers to two separate
factors. The first factor relates to the shape and style of the cut e.g.
Pear, Round, Marquise, Princess, Brilliant Heart shaped etc. The second
factor is the way the rough diamond is cut to produce a polished
diamond. The effects of a good diamond cut result in the heightened
levels of brilliance, fire, sparkle and luster of a diamond. A diamond
cuts with good proportions reflect more light and appear to look better
than other diamonds of higher clarity and appear to look 2 or 3 grades
higher than the actual color. The quality is also dependent upon the cut
of the diamond facets.
Information about
the 4 C 's to Diamonds - The Clarity
The Clarity, another
important category in the 4C 's, relates to exactly how clear a diamond
is and describes the presence, or absence, of
Diamond Inclusions (flaws) within
the diamond and any blemishes on its surface. Inclusions disrupt the
flow of light in the diamond so that some of light reflected will be
lost. The numbers, sizes, colors, locations and visibility of any
inclusions or blemishes can effect the relative clarity of a diamond and
its quality. The majority of diamond inclusions cannot be seen
by the human eye so systems have been developed to grade diamond clarity
as detailed in a

Chart.
