Diamond Guide



Clarity is an important issue to consider when buying a diamond. The clarity of a diamond will determine how much light is reflected from within the diamond, and therefore will affect the diamond’s brilliant sparkle and glimmer. A diamond absorbs the surrounding light through the crown (the top) and as the light travels through the diamond it is bounced off of the diamond’s angles and directed back up through the top of the diamond. Clarity quality is determined by considering the flaws of a diamond which essentially block light from passing back up through the surface. A diamond's clarity can be affected by two types of flaws:

These are any of the impurities that are on the surface of the diamond. External flaws are the result of wear and tear on the diamond or from damage caused during cutting.

These are any of the many impurities that reside solely in the interior of the diamond. There are many kinds of internal flaws. A few important ones that you should familiarize yourself with are: * Black or dark spots: Carbon or other dark spots. * Clouds: Clouds are microscopic inclusions that lower transparency. * Fracture (feather): The majority of imperfections in diamonds are the result of breakage or fractures, in the diamond chemical structure.

The common scale used is based on 10-power magnification (hand held loupe or microscope). This means that for all practical purposes, any imperfection that is too small to be seen with x10 magnification does not "exist" when grading a diamond.

Purer the diamond, the greater its quality!

The GIA defines the qualifications for each group in the scale as follows:


Internally flawless (and flawless) group: FL-IF

The highest clarity grade given. The diamond in question will be without imperfections visible with x10 magnification. Some blemishes may be permitted externally bringing the stone to clarity of flawless; or Internally Flawless.

Very slightly included group: VVS1 and VVS2
The VVS group is divided into two, VVS1 and VVS2: The VVS inclusion in question will be very hard to detect, even for an experienced examiner using x10 power magnification.

Very slight included group: VS1 and VS2
The definition of this group is as follows: The VS inclusion in question will be hard to detect, even for an experienced examiner using x10 power magnification.

Slightly included group: SI1, SI2 and SI3
The majority of engagement diamonds bought today is of the SI range: Inclusions and imperfections in this group may be visible easily with the aid of x10 magnification. SI3, a relatively new grade added by some laboratories to bridge the very wide gap between SI2 and I1 (imperfect).

* SI1: Can be seen easily with x10 magnification. Cannot be viewed with the naked eye. * SI2: Can be seen easily with x10 magnification. Rarely can be viewed with the naked eye. * SI3: Can be seen very easily with x10 magnification. In most cases (stones above 3/4 of a carat) can be viewed with the naked eye.


Color is another important factor in choosing the right diamond for your ring. Since color itself acts as a filter (think of the way rose colored glasses take away certain harsh or vibrant colors when looked into), the color quality is very important to diamonds because the more color your diamond has, the less fire or sparkle will be exuded from its crown. In other words, your diamond takes in light similar to a prism and reflects its colors, called fire. Fire gives a diamond its beautiful sparkle, and to ensure that you have the right diamond for you consider the following standards for color quality.

D-E-F: Colorless. This is the colorless diamond group. They are common enough to be found in any store, but still command the highest prices. D and E show virtually no color. F starts to show the very slightest of color and is the transitional color to the next group.

G-H-I: Near colorless. This is the near colorless group. If you are looking for value when you shop, ask to see stones from this group. These diamonds begin to exhibit a very light shade of color, but it is hard to detect in mounted stones.

J-K-L-M: Faint yellow. This is the group that begins to show slight yellow color which may be noticeable from the top of the stone and even more from the sides.

To ensure highest quality in all our products, Wedding Bands Wholesale does not work with diamonds beyond I color and all of our diamonds are graded for color prior to mounting.
