Expensive diamonds – Understanding the Four C’s

Categories :

Diamond are one of the particular world’s most respected natural resources, not to mention one of the most highly desired gemstones. Diamond are naturally made with an enormous number of characteristics, generating every individual diamond unique. The many possible mixtures of the characteristics determine the overall quality plus associated with a gemstone. Recognizing the have to have for an common grading system, GIA, the Gemological Company of America, regarded as the world’s respected institute of gemological research, developed typically the Four C’s. Typically the Four C’s symbolize Cut, Color, Clearness, and Carat Weight. This internationally approved diamond grading program has revolutionized typically the diamond trade and even today is employed by simply nearly every professional in the industry and diamond fanatics across the earth. Because individual precious stone vary so profoundly in quality plus price, it will be vital for customers to be familiar with the 4 C’s too. We now have outlined basic principles involving this grading method below, to aid give consumers the resources they should help to make educated purchases.


The cut regarding a diamond may be one of the most important of the Four C’s, and can boost the overall high quality, value, and splendor of that diamond. There are a lot of different cuts, each and every having a certain effect on typically the following three features:

* Brightness — the amount involving light the diamond reflects

* Flames – the various colors from the variety that a diamond gives off

3. Scintillation – the particular sparkle and beauty that is produced when a diamonds is moved

Inside a well cut diamond, the sunshine which enters with the stand (the top level facet) and moves through to typically the pavilion is next reflected and allocated through the top, creating a desired effect. Unfortunately, found in a poorly cut diamond, some of the light leaks your girdle, which dramatically minimizes the diamond’s twinkle.

The quality associated with a diamond cut is located primarily on symmetry and gloss, plus the proportions associated with the table dimension, crown angle, plus pavilion depth to be able to one another. In most cases, the greater facets a diamond has, the more brilliance and sparkle it will have. However typically the depth of the pavilion also has some sort of huge impact upon this. Once the level of the stand is either too much delete word adequate, the light can be lost out the particular sides of the particular stone as opposed to getting directed with the the queen’s.

The brilliant rounded cut diamond is usually by far the most common with the diamond cuts, although many others are increasing popularity. The amazing round cut was designed specifically with regard to use on diamond, with it’s 57-58 well proportioned aspects, it’s brilliance and even sparkle is more noticeable than in most cuts. However with so numerous variations of precious stone cuts, many mixtures of proportions are usually possible, directly impacting on the advantage of a precious stone, and thus also the particular value.


Related to the slice of any diamond, is actually color will either increase or reduce it’s sparkle and even fire. Obviously, diamonds with less shade will reflect more light than all those with a mild yellow or brownish hue. This, combined with the fact that mother nature provides us along with less of these kinds of colorless diamond, makes them more valuable and sought after.

Again seeing the particular need for a good universal system, typically the GIA developed typically the diamond color grading scale, using the letters D-Z, which is most widely accepted today. Diamond are graded under very precise viewing conditions and often in comparison to diamond of a new known color class to make certain very several differences inside a shade grade. A precious stone absent of colour is grade ‘D’ and the even more color that is found in the diamonds, the further together the alphabet is actually grade travels. Precious stone with grade ‘Z’ will have a mild yellow or brown tint, and therefore will not likely reflect light-weight and a colorless diamonds. Fancy colored precious stone, although most are irradiated and color enhanced, never follow this grading size, and often will be more valuable because any time naturally colored they can be extremely rare.

The most typical color grades are G through I, as they usually are more abundant in character, and much more affordable. Opal Although diamonds of the grades do have a hint of color, it typically isn’t visible in order to the naked and untrained eye. Similarly, diamond graded L through M might have a very faint hue of green, good results . the perfect jewelry piece and even diamond cut, the particular color may look less obvious (although it barely is usually to begin with). White gold or platinum adjustments usually require better grade diamond, whereas a yellow gold setting takes aside from the yellow hue tint of the lower grade diamond.

Most jewelers employ the GIA Precious stone Color Grading Size [out], in addition to it’s recommended for customers to do typically the same to higher understand the subtle differences in color a precious stone may have, in addition to to better examine the quality in addition to value of some sort of diamond.


In accordance to the GIA, “diamond clarity appertains to the absence of inner inclusions or exterior blemishes. ” Involving all diamond qualities, clarity may be the 1 with the best impact on a diamond’s value, given that flawless diamond are so rare. Organic diamond are set up deep within the planet under extreme stress, so it’s not necessarily surprising that almost all diamond have got minor flaws. You will find two types associated with flaws – imperfections and inclusions. Blemishes are external faults located on the surface involving a diamond, and include chips, nicks, and scratches, almost all of which occur in the cutting process. Fillings are internal faults such as bubbles, cracks, or other minerals within the center from the precious stone.

GIA developed a great universal diamond clearness grading scale containing of 11 degrees. Diamond are ranked under 10x zoom, so most regarding the flaws of which affect the quality grade are hardly visible to the particular naked eye. In addition to the number, size, in addition to severity of typically the inclusions, the positioning and color of the inclusion are also considered when grading the clarity of a diamond. Given that no two gemstone are alike, the characteristics of some sort of diamond and is actually inclusions help it become entirely unique, and are occasionally used, like fingerprints, to identify person diamond.

The the majority of rare clarity levels are F or even FL (flawless) plus IF (internally flawless), diamond of the degrees are much a lot more valuable because these people never occur since often in mother nature. The next greatest clarity grades are VVS (very, quite slightly included) in addition to VS (very slightly included). These diamond are more frequent and sought following because they are usually less expensive than exquisite diamond yet even so have very slight inclusions, the majority of which often can only end up being seen under addition by the skilled grader. Likely the nearly all common clarity level is SI (slightly included). Diamond on this clarity are still considered “eye-clean” and provide an affordable alternative. The lowest clearness grade, I (imperfect), has more noticeable inclusions which might affect the brilliance of the diamonds.

GIA defines their very own clarity grading level as follows:

* Exquisite (FL)

No fillings or blemishes happen to be visible to the skilled grader using 10x magnifying

3. Internally Flawless (IF)

No inclusions and even only minor blemishes are visible to some skilled grader employing 10x magnification

5. Very, Very A little bit Included (VVS1 in addition to VVS2)

Inclusions are difficult for a skilled grader to be able to see under 10x magnification

* Quite Slightly Included (VS1 and VS2)

Fillings are clearly obvious under 10x magnifying but may be characterized as small

2. Slightly Included (SI1 and SI2)

Fillings are noticeable to a skilled grader using 10x zoom

* Imperfect (I1, I2, and I3)

Inclusions are evident under 10x magnification and may impact transparency and splendour


The pounds of a diamonds is measured in carats, with 1 carat equaling 200 milligrams or 1/5 gram. You may well also hear typically the term “points” applied when speaking of diamond weight. One carat is broken down up into 100 points, so a new 1/4 carat precious stone can be referred to as a ’25 point diamond. ‘

Although carat pounds is additionally used to measure gemstones, it is slightly even more complicated, since gemstone types may have different densities. Due to the fact of this, some sort of round 6mm Alexandrite may have a karat weight of just one. 30ct whereas a circle 6mm Citrine might only be 0. 70ct.

When written, carat is generally abbreviated as ‘ct. ‘ In a new jewelry piece using several diamond, the particular abbreviation used is definitely ‘ct TW’ meaning carat total bodyweight (the sum of the particular carat weights intended for each diamond), though that’s usually shortened to ‘ctw. ‘ The value of such a jewellery piece may become below the price of a related item of the particular same carat pounds with only 1 diamond. Diamond solitaires are much even more rare, and therefore, a 1ct Precious stone Solitaire ring will be worth much more than some sort of similar 1ctw diamond ring numerous smaller diamonds.

Similarly, diamond associated with the same dimension and carat excess weight might not hold typically the same value, because one may possess better clarity or even color. The cut of a diamond also affects is actually carat weight and benefit because some precious stone cuts hold a lot more volume than others.

The Four C’s as outlined above are the main characteristics which affect typically the value of a new diamond. However just as important is that they categorize the diamond’s unique beauty, and standardized the grading method utilized to classify the particular quality of person diamond. We highly recommend for consumers to teach themselves about diamonds grading and some other related jewelry facts.
