Diamond jewelry – Understanding typically the Four C’s

Diamond happen to be one of the particular world’s most appreciated natural resources, not really to mention probably the most highly desired gems. Diamond are naturally made with an enormous selection of characteristics, making every person diamond exclusive. The countless possible mixtures of these characteristics determine the overall quality and even associated with a diamond. Recognizing the want for an universal grading system, GIA, the Gemological Company of America, viewed as the world’s looked upon institute of gemological research, developed typically the Four C’s. The particular Four C’s stand for Cut, Color, Clarity, and Carat Excess weight. This internationally acknowledged diamond grading program has revolutionized the particular diamond trade in addition to today is employed by nearly every qualified in the sector and diamond fans across the world. Because individual gemstone vary so profoundly in quality and price, it is definitely vital for customers to be common with the Several C’s at the same time. We’ve outlined the basic principles involving this grading method below, to support give consumers typically the resources they should help make educated purchases.


The cut associated with a diamond is usually the most significant of the Four C’s, and can easily improve the overall good quality, value, and elegance of that diamond. There are several different cuts, every single having a certain effect on the particular following three attributes:

* Brightness instructions the amount involving light the precious stone demonstrates

* Fire – the several colors from the variety that a precious stone gives off

3. Scintillation – typically the sparkle and beauty that is produced when a precious stone is moved

Inside of a well slice diamond, the sunshine which often enters through the table (the top toned facet) and travels through to typically the pavilion is then reflected and distributed through the overhead, creating a desirable effect. Unfortunately, found in a poorly reduce diamond, some of the light source leaks the actual belt, which dramatically minimizes the diamond’s sparkle.

The quality involving a diamond reduce is based primarily on symmetry and enhance, along with the proportions associated with the table dimension, crown angle, and pavilion depth to one another. In most cases, the more facets a precious stone has, the even more brilliance and sparkle it will certainly have. However the particular depth of the pavilion even offers some sort of huge impact about this. When the level of the pavilion is either as well much delete word sufficient, the light may be lost out the sides of the particular stone instead of appearing directed through the crown.

The brilliant rounded cut diamond is usually by far the most common of the diamond cuts, although a lot of others are getting popularity. The amazing round cut was initially designed specifically for use on diamonds, with it’s 57-58 well proportioned aspects, it’s brilliance plus sparkle is more noticeable than on most cuts. But with so several variations of gemstone cuts, many mixtures of proportions are possible, directly affecting the advantage of a diamond, and so also typically the value.


Related to the trim of the diamond, really color will both increase or lower it’s sparkle and fire. Obviously, diamonds with less shade will reflect additional light than those with a lighting yellow or brownish hue. This, combined with the fact that characteristics provides us along with less of these kinds of colorless diamond, makes them more valuable and sought after.

Once again seeing the particular need for a good universal system, the particular GIA developed the particular diamond color grading scale, using typically the letters D-Z, which usually is most widely recognized today. Diamond are generally graded under very precise viewing circumstances and often compared to diamond of the known color grade to assure very number of differences within a coloring grade. A gemstone absent of colour is grade ‘D’ and the more color that is found in the diamonds, the further along the alphabet really grade travels. Gemstone with grade ‘Z’ will have a light yellow or dark brown tint, and as a result will not likely reflect light source in addition to a colorless precious stone. Fancy colored precious stone, although most will be irradiated and shade enhanced, do not follow this grading scale, and often are more valuable because when naturally colored they are extremely rare.

The most frequent color grades are G through I actually, as they are more rich in mother nature, and much even more affordable. Although diamond of these grades carry out have a hint associated with color, it normally isn’t visible to the naked plus untrained eye. Similarly, diamond graded M through M may have a very faint hue of green, but with the ideal jewelry piece and even diamond cut, typically the color may seem less obvious (although it barely is to begin with). White gold or platinum or platinum adjustments usually require higher grade diamond, although a yellow precious metal setting takes apart from the green tint of the lower grade diamond.

Most jewelers use the GIA Diamonds Color Grading Size [out], plus it’s recommended can be to do the same to better know the subtle differences in color a gemstone may have, and to better examine the quality in addition to value of a new diamond.


In accordance to the GIA, “diamond clarity appertains to the absence of inside inclusions or external blemishes. ” Involving all diamond attributes, clarity could be the one particular with the very best impact on a new diamond’s value, considering that flawless diamond will be so rare. All-natural diamond are made full within the world under extreme pressure, so it’s not surprising that nearly all diamond include minor flaws. You can find two types regarding flaws – scars and inclusions. Blemishes are external flaws located on the surface involving a diamond, and include chips, grazes, and scratches, the majority of which occur through the cutting process. Blemishes are internal defects such as pockets, cracks, or other minerals within typically the center of the gemstone.

GIA developed the universal diamond clearness grading scale consisting of 11 marks. Diamond are ranked under 10x magnifying, so most associated with the flaws that affect the clearness grade are barely visible to the particular naked eye. Found in addition to typically the number, size, plus severity of the particular inclusions, the positioning and even color of typically the inclusion are furthermore considered when grading the clarity of a diamond. Since no two diamond are alike, the characteristics of a new diamond and is actually inclusions help it become entirely unique, and they are at times used, like finger prints, to identify individual diamond.

The almost all rare clarity degrees are F or perhaps FL (flawless) and IF (internally flawless), diamond of those degrees are much a lot more valuable because these people never occur while often in mother nature. The next finest clarity grades are usually VVS (very, really slightly included) plus VS (very a bit included). These diamond are more frequent and sought after because they are usually less expensive than perfect diamond yet even so have very slight inclusions, most of which in turn can only be seen under zoom by a skilled grader. Likely the almost all common clarity level is SI (slightly included). Diamond of the clarity are even so considered “eye-clean” and provide a relatively inexpensive alternate. The lowest clarity grade, I (imperfect), has more visible inclusions which may affect the beauty of the diamonds.

GIA defines their particular clarity grading level the following:

* Perfect (FL)

No fillings or blemishes happen to be visible to a new skilled grader using 10x magnification

3. Internally Flawless (IF)

No inclusions plus only minor imperfections are visible into a skilled grader applying 10x magnification

2. Very, Very A bit Included (VVS1 and even VVS2)

Inclusions are usually difficult for some sort of skilled grader to see under 10x magnification

* Really Slightly Included (VS1 and VS2)

Fillings are clearly visible under 10x magnifying but could be recognized as minor

2. Smaragde Slightly Included (SI1 and SI2)

Inclusions are noticeable in order to a skilled grader using 10x magnification

* Imperfect (I1, I2, and I3)

Inclusions are apparent under 10x zoom and may affect transparency and splendour


The pounds of a gemstone is measured in carats, with one carat equaling two hundred milligrams or 1/5 gram. You may possibly also hear the particular term “points” used when speaking of diamond weight. A single carat is divided up into one hundred points, so some sort of 1/4 carat diamonds will be referred to as a ’25 point diamond. ‘

Although carat body weight can also be used in order to measure gemstones, it is slightly more complicated, since gemstone types may include different densities. Since of this, a new round 6mm Alexandrite may have a carat weight of just one. 30ct whereas a round 6mm Citrine may well only be zero. 70ct.

When composed, carat is usually abbreviated as ‘ct. ‘ In the jewelry piece using several diamond, the abbreviation used is definitely ‘ct TW’ that means carat total pounds (the sum of typically the carat weights with regard to each diamond), though that’s usually reduced to ‘ctw. ‘ The value associated with such a precious jewelry piece may end up being lower than the price of a related item of the particular same carat fat with only one diamond. Diamond solitaires are much additional rare, and as a result, a 1ct Gemstone Solitaire ring can be worth much more than a similar 1ctw diamond ring with many smaller precious stone.

Similarly, diamond associated with the same dimension and carat weight might not hold the particular same value, due to the fact one may possess better clarity or perhaps color. The minimize of a precious stone also affects is actually carat and benefit because some diamond cuts hold a lot more volume than other folks.

The Four C’s as outlined over will be the main features which affect the value of the diamond. However just as important is that they sort the diamond’s special beauty, and standard the grading program utilized to classify the particular quality of specific diamond. We recommend for consumers to teach themselves about precious stone grading and additional related jewelry facts.
