Diamonds are available in many shapes. More than 3/4 of diamonds sold are round diamonds.
Princess cuts are also a very popular diamond shape and are commonly used in engagement rings.
Diamond shapes available include:
Round, Princess, Emerald, Radiant, Oval, Pear, Marquise and Heart.
The cut of a diamond may be the most important of the 4 C's because it determines the brilliance
of the diamond.
Brilliance of a diamond refers to how light enters into a diamond and reflects back out.
Diamonds with more brilliance
reflect more light back out than those with less brilliance. Mondera grades the cut of its
diamonds as Ideal, Premium, Very Good or Good
The 'Hearts and Arrows' cut is a special cut of round diamonds. They are more rare and expensive because of the
skill and precision needed to create them. They are called 'Hearts and Arrows' because when using
a special scope a pattern of hearts and arrows can be seen inside the diamond.
Inclusions are scratches or blemishes either on or inside a diamond. The clarity of a diamond
is rated based on the number and size of inclusions. Diamonds that have no inclusions are
referred to as flawless (F) or internally flawless (IF). These diamonds are very rare and expensive.
Diamonds are graded for their clarity as follows:
F,IF (Flawless, Internally Flawless)
VVS1, VVS2 (very, very slightly included) - inclusions are hard to see under magnification
VS1, VS2 (very slightly included) - inclusions not visible without magnification
SI1, SI2 (slightly included) - might be visible to the naked eye
I1, I2, I3 (included) - inclusions are visible
White diamonds are generally not completely clear - they usually have a faint yellowish color
to them. Diamonds that have less color are more rare and are more expensive because more light
can pass through and reflect back off them. Diamonds are rated for their colorlessness on a scale
that starts with the letter 'D' and goes down through the alphabet - D to Z. D rated
diamonds are the most clear, and most expensive. Mondera only sells diamonds rated D - M.
D - F - nearly clear and the most valuable
G - I - have very little color
J - M - slightly pale yellow
N - R - very light yellow
S - X - light yellow
The weight of a diamond is measured in carats (not the same as 'karat', which measures the
purity of gold). A carat is equal to 200 milligrams. Larger, heavier diamonds are more
rare and more expensive. Carats are often abbreviated as 'ct.' or even 'TDW'. They are
usually expressed as either a fraction or decimal. For example, one fourth of a carat
could be written as '.25' or '1/4 ct.' Typical values of diamond carats in jewelry
are .25 (1/4), .33 (1/3), .50 (1/2), .75 (3/4), 1.00 and 2.00, although smaller carat
values are also common. As expected, diamond jewelry with a carat weight of 1.00 or
2.00 is much more expensive.
