While buying a diamond, one should always check the 4Cs that so that he/she makes
the best choice. 4Cs used for valuation of diamonds and refer to Color, Clarity,
Cut, and Carat weight.
Cut plays an important role in deciding a diamond's brilliance. Brilliant round
diamonds have around 58 facets, 33 of them are on top of the diamond body. There
are 24 crown or star facets at bottom, which are known as pavilion facets. Many
times the line connecting pavilion and crown is faceted too but are not a part of
round brilliance cut.
All the facets of a diamond should be in the geometrical relations with each other.
You can be sure about the quality of diamond if you do not find any bow tie and
fish eye in it. Due to fish eye, diamond looks larger and spread out but with lower
brilliance. With bow ties, there is a black region formed on the diamond, making
it undesirable.
Color is also an important determinant for finding the diamond's worth. Colorless
diamonds are of the highest value where traces of color depreciate its value. Most
of the diamonds seem colorless to naked eye but majority of these diamonds have
tint of brown and yellow when they are under illumination and Tripod. Nature diamonds
are found in blue, red, deep yellow and green shades. These are also known as fancy
colorful diamonds basing on alphabetical scale start from colorless D to yellow
M.
Clarity of the diamonds is dependent on a number of factors including location,
number, type, and size of inclusions. Inclusion is imperfection or the mineral traces
in stone, visible only under magnification of the loupe of jeweler. Fewer inclusions
in a diamond, better brilliance, and clarity it has. Fewer inclusions also mean
higher prices.
Carat is another determinant for finding out diamond's value. Weight of the diamonds
is measured in carats. Every carat is further divided in the 100 points. A carat
weight is not of any use without considering clarity, color, and cut of the diamonds.
Large diamonds are not that worthy if they lack purity, better grade color, and
brilliance. Since larger diamonds are rare to find as compared to the smaller ones,
value of the diamond increases exponentially with the carat weight.
You will not find similarity between any two diamonds. You must find out their value
on basis of 4Cs i.e. Cut, Clarity, Color, and Carat while doing diamond shopping.
