Before you buy any diamond, it is important that you become familiar with the 4 C's of Diamonds and how they help determine the beauty, rarity, and price each diamond is attributed. All diamonds are rare, but some are rarer than others - and therefore more valuable. The 4C’s relate to a diamond’s CUT, COLOR, CLARITY, and CARAT WEIGHT. Predictably, the better these four characteristics rank accordingly, the more desireable and truly beautiful each diamond will be!

Cut
beauty and life of the diamond! When a diamond is cut to good proportions, light is internally reflected from one facet to another, and then dispersed through the crown, or the top, of the diamond. If the diamond is cut too deep, then some light will escape through the opposite side of the pavilion, or bottom, of the diamond. If it is cut too shallow, then some light will escape through the pavilion, or bottom, before it can be reflected. A well cut (“ideally cut”) diamond is comprised of facets with the correct angles which are perfectly placed to maximize the diamond’s brilliance. It is the quality of the cut (the “make”) and its final polish that unlocks the hidden beauty.

The way a diamond is cut and polished is vital. It is the precision and delicacy of the cut that dictates the maximum amount of light the diamond will refract and reflect. The better it has been cut (to proportions established as “ideal”), the greater its brilliance, its fire, and real

Color
The most prized diamonds are colorless diamonds, because their beauty depends entirely upon their remarkable optical properties. In these diamonds, all the colors of the rainbow are reflected back to your eye. Although composed of carbon, all diamonds usually include traces of
other elements. These elements being present during the intense formation process may have been incorporated within the diamond in trace amounts, and will affect the true color of a diamond. Nitrogen and boron are two of these most commonly present in diamonds, and give the diamond its color, or lack of it. It is these subtle shades of color that are difficult for the untrained person to detect, but which determine the diamond’s value and overall beauty. There are those diamonds that exhibit
intense colors, most notably yellow, blue, red, or green, and these diamonds are called “fancies” within the industry. They certainly are both rare and beautiful, but are not the colorless diamonds most of us expect to find.
The color scale varies from totally colorless to light color or tinted. The only true way to determine the colorlessness of a diamond is to compare each specimen to a graded Master Set. On the GIA color grading scale, D, E, and F are colorless, and simply extremely rare in occurrence in nature, and thus much more costly than a near-colorless diamond with a G-H-I-J grade, which are more abundant. Color may become noticeable in some J-graded diamonds, and definitely in grades L and below (which for years have been referred to as TLB - Top Light Brown). Most “better” choices will be found in the G-H and I grades, for they are certainly beautiful, and being more abundant in occurrence, offer a wider selection of affordability. An ideally cut diamond, even with a J grade, might be more appealing than a higher graded diamond with an average cut. Color has an important bearing on our immediate determination of desirability, but is only one of the critical characteristics we must evaluate.

Color has an important bearing on our immediate determination of desirability, but is only one of the critical characteristics we must evaluate.
Clarity
Because of their unique optical properties, diamonds, more than any other gemstone are capable of producing the maximum amount of brilliance by interacting with light. While minute crystals of diamond or other minerals are contained in almost every diamond (which we call
inclusions), a diamond that is virtually free of inclusions and surface blemishes will be judged as “Flawless.” These diamonds are extremely rare, and occur so infrequently in nature that they command a significant premium. Inclusions may impede light as it reflects and refracts through a diamond, which is why considering the clarity of a diamond addresses more than simply visible imperfections ("Imperfect" grades - I1, I2, etc.). Understanding this balance is important in determining a diamonds desireability with regard to the 4C's and how they inter-relate to establish each diamond's value.
To determine a diamond’s clarity grading, it must be examined under 10x magnification by a trained, skilled eye, and often compared with a Master Set of diamonds to properly grade and evaluate. In most labs, a consensus of gemologists must be reached before a grade is issued. Whatever minute inclusions may be present make every diamond thus unique. These are, in fact, nature’s “fingerprints” and do not mar the diamond’s beauty nor endanger the diamond’s durability. Without high magnification, you may never see these inclusions (in grades SI-2 and above), and the fewer you do see, the rarer your diamond will be. As with the other characteristics of diamonds, clarity is obvious when you can see the inclusions with your naked eye easily under most lighting (clearly an I-2 and below). Some I-1 clarity grades are for the most part unnoticeable, and may yet be a desirable diamond even with such a grade.
GIA grades explained: FL- “Flawless,” no inclusions internally or externally under 10x magnification; IF- “Internally Flawless,” may have very slight surface inclusion, polish mark, or blemish; VVS-1 and 2 - “Very Very Slight Inclusions” inclusions difficult to detect by trained eye; VS 1 and 2- “Very Slight Inclusions” inclusions detectable by trained eye; SI 1 and 2- “Slight Inclusions” easily detectable under 10x magnification; I1 and below- “Imperfect,” inclusions that should be visible to the naked eye without magnification.

Carat
The last of the four C’s is Carat Weight. A diamond’s weight is the simplest of its characteristics to ascertain, as it refers to a static measure, and from the earliest of times has been used to calculate one aspect of the value of a diamond. The carat is a unit of weight that is a derivative from ancient use of the carob seed as a standard measure of weight. Invariably, the carob seed, from the pods of the carob (or locust) tree contain tiny seeds which are remarkably consistent in weight. These seeds were used by the early gem traders to measure their diamonds and other treasures. A 1 carat diamond used to equal the weight of a single carob seed, but in today’s terms, the carat is a standard metric weight of 0.2 grams, or 1/142 of an ounce.
Each carat is divided into 100 “points.” So, for example, a quarter of a carat is the same as 25 “points” written as 0.25; a half a carat is 50 points written as 0.50, and so on. It is easy to weigh an unmounted diamond, but it is only possible to estimate the weight of a mounted diamond using special gauges and formulae. Remember, Carat Weight has no bearing on a diamond’s cut, color, or clarity, but grade for grade a larger diamond is infinitely more rare and valuable than a smaller specimen. Carat weight is obviously the first aspect of the diamond she will notice (and that is why when it comes to diamonds, size does indeed matter!), but the understanding the fineness of a diamond requires a more appreciative and informed awareness of the 4C's of diamonds!
