THE ANATOMY OF A DIAMOND
Proportion refers to the angles and relative measurements of a polished diamond. More than any other feature, proportions determine a diamond's optical properties.
Studies have shown that table size, crown angle, and pavilion depth have a dramatic effect on a diamond's appearance.
Symmetry is a grading term for the exactness of shape and placement of facets. Variations in symmetry include off-center culets and tables, poor facet alignment, misshapen facets, out-of-round girdles, and wavy girdles.
Once cut and polished, all diamonds possess a shared set of characteristics, often referred to as the anatomy of the diamond. While the individual proportions, angles and placement of these common characteristics vary for diamonds of different shapes, their definition is the same.
THE VALUE OF A DIAMOND: THE FOUR C'S
When you are planning on purchasing a diamond it is important that you know as much as possible about how diamonds are classified.There are four topics you need to become familiar with ?Cut, Color, Clarity, and Carat Weight of a diamond.
A) When a ray of light touches the surface
of a diamond, part of the light is
reflected back, this is external reflection.
B) The rest of the ray penetrates the
stone and is then reflected toward
the center of the diamond.
This is known as refraction.
C) The ray of light is reflected to the
surface, where it is seen as the colors of
the spectrum. This is known as dispersion.
The Cut is the factor that determines the brilliance of a diamond. A classic round brilliant cut diamond has 58 facets : 33 on the top, 24 on the bottom, and the culet (1 point at the bottom). Each of the diamond's facets must be placed in exact geometric relation to one another when the stone is being cut. Quality diamonds must be properly cut and not "spread", which means that the proper proportions are compromised to make the diamond weigh more.
FL-EF | Flawless or Internally Flawless. No internal inclusions.
VVS1-VVS2 | Very Very Small inclusions. Very difficult to see under 10x magnification.
VS1-VS2 | Very Small inclusions. Can bee seen under 10x magnification and in some cases to the naked eye.
SI1-SI2 | Small inclusions. Can bee seen under 10x magnification and may be visible to the naked eye.
I1-I2-I3 | Imperfect. Inclusions are visible under 10x magnification and in most cases to the naked eye.
The Clarity of a diamond is based on the number, location, size, and type of inclusions found in the stone. An inclusion is an imperfection or trace mineral in the stone that is visible under the magnification of a jeweler's loupe. The fewer inclusions the diamond has; the clearer, more brilliant and more expensive the diamond will be. A "Flawless" diamond is one that has no inclusions and is extremely rare and valuable.
Colorless and near-colorless diamonds are the most valuable. Though most diamonds may appear colorless to the naked eye, the majority of diamonds contain slight traces of yellow or light brown when viewed under a jeweler's loupe. Depending on the stone's size, a single increase in color grade can boost the value of a diamond by thousands of dollars per carat. A traditional engagement diamond is usually colorless or near-colorless.
In nature, diamonds can also occur in shades of red, pink, blue, green and deep yellow - These are called
"Fancy diamonds". In the United States and around the world colorless diamonds are graded on an alphabetical
scale, introduced by the Gemological Institute of America (GIA). "Colorless" or "rare white" diamonds are of color
grades D, E and F. Diamonds of color grade D are very rare, and extremely valuable.
DIAMOND CARAT WEIGHT
The weight of a diamond is measured in carats (ct.). Each carat is divided into 100 points. For example:
1ct.= 100 points, 1/2 ct. = 50 points, etc. The carat weight alone is almost meaningless unless you also consider
the cut, clarity and color of the diamond. A large diamond is not very valuable if it lacks brilliance, purity and
However, since larger stones are rarer than smaller ones, diamond value rises exponentially with carat weight.
Therefore, a diamond weighing 3.0 carats, will always be worth more than three 1.0 carat stones of the same
quality. No two diamonds are exactly alike, and you must weigh all of the factors - color, cut, clarity and carat
weight - when making your diamond jewelry buying decision.
