4 C'S of diamond


The word cut has different meanings. It is synonymous with the making: a combination of operation [cleaving, sawing, bruiting, polishing] resulting in the shape of a diamond. These may have different forms and various styles: rose cut, brilliant cut, mixed cut, etc.

Everything that contributes to creating certain conditions, good or bad, of brilliance, dispersion, scintillation, intervene with the quality of the cut. These are proportion, polish, symmetry.

The nature of the “cut” makes a distinction in how a diamond cutter brings out the beauty of a diamond.

Diamond cut is maybe the most critical of the four C’s, so it is imperative to see how this quality influences the properties and estimations of a diamond. A decent cut gives a diamond its splendor, which is that brilliance that appears to originate from the very heart of a diamond. The edges and finish of any diamond are what decide its capacity to deal with light, which prompts brightness.

As appeared in the pictures beneath, when a diamond is well-cut, light enters through the table and goes to the structure where it reflects from one side to the next before reflecting pull out of the diamond through the table and to the eyewitness’ eye. This light is the brilliance we referenced and it’s this flashing, fiery effect that makes diamonds so hypnotizing.

In an ineffectively cut diamond, the light that enters through the table achieves the features and after that ‘spills’ out from the sides or base of the diamond instead of reflecting back to the eye. Less light reflected back to the eye implies less brightness.



Choosing the evaluation of cut is extremely a matter of inclination. To make the best determination, you have to comprehend the different evaluations. It would be ideal if you note that the depictions underneath are general rules.

Ideal cut

This cut is proposed to amplify brilliance, and the ordinarily littler table sizes of these diamonds have the additional advantage of making a lot of scattering or ‘fire’ also. Perfect quality diamonds are genuinely for the individual who appreciates realizing that he has one of the best things that cash can purchase. This class applies just to round brilliant cut diamond.


On account of a round diamond, numerous Excellent Cut diamonds have cuts that are the equivalent of an Ideal Cut diamond, however, they frequently can be bought at marginally lower costs than AGS Ideal Cuts. They are expected to give the greatest brilliance and fire. Like the Ideal Cut, these are additionally for the individual who appreciates realizing that he has one of the best things that cash can purchase.

Very good

These diamonds reflect the vast majority of the light that enters them, making a decent arrangement of brilliance. With these diamonds, the cutters have strayed somewhat from the favored diamond extents so as to make a bigger diamond. The outcome is that these diamonds fall marginally outside of certain clients’ inclinations as far as, for instance, table size or girdle width, however, much of the time a large number of the parameters of diamond in this range will cover with specific parameters of diamond in the Ideal or Excellent extents. For the most part, the cost of these diamonds in somewhat beneath that of Excellent cuts.


Diamonds reflect a significant part of the light that enters them. Their extents fall outside of the favored range on the grounds that the cutter has made the biggest conceivable diamond from the rough crystal, as opposed to cutting additional load off to make a littler Excellent quality diamond. Diamond in this range offers a great cost-funds to clients who need to remain in a financial plan without giving up quality or excellence.


A diamond evaluated as reasonable or poor reflects just a little extent of the light that enters it. Regularly these precious stones have been cut to expand the carat weight over most different considerations.



  • Diameter

The width of the diamond as estimated through the girdle.

  • Table

The table is the vast, level plane at the exceptionally top of the diamond. It is the biggest facet on a stone, frequently called the Face. The term Table Spread is utilized to portray the width of the table facet, regularly communicated as a level of the all-out width of the stone.

  • Crown

The crown is likewise called the top of the stone. As the name proposes, it is the upper bit of the stone, the part over the girdle. The capacity of the crown is to split the entering white light into colored light which thus bestows fire impact in the diamond.

  • Girdle

The girdle is the edge of the stone that shapes its edge. It is the edge shaped where the top part of the stone meets the base segment. It is the separating line among crown and pavilion.

  • Pavilion

The pavilion is the base part of the stone, the part from the girdle to the point at the base. The activity of pavilion is to reflect back the light entering through the crown. This marvel bestows brilliance impact in a diamond.

  • Culet

The culet alludes to the “point” at the base, which is really not a point but rather a little facet. The littler the culet of the diamond, it implies better is the cut of a diamond. Anyway these days, numerous diamond is cut without a culet.



The degree by which, the saturation of the inherent color of the stone differs from the ideal colorless state.The less color in a diamond, the rarer it is [other than fancy colored diamonds. These diamond, which is exceptionally uncommon and over the top expensive, can be any shading from blue to green to bright yellow. They are in reality increasingly profitable for their color].

The best shading for a diamond is no color by any stretch of the imagination. An absolutely colorless diamond enables light to go through it effectively, bringing about the light being scattered as the color of the rainbow. colors are reviewed absolutely colorless to light yellow. The distinctions from one evaluation to the next are exceptionally inconspicuous and it takes a prepared eye and long stretches of understanding to color grade a diamond.

To review ‘whiteness’ or colorlessness, most diamond setters refer to GIA’s expert color scale that starts with the most astounding rating of D for colorless and goes down the letter set to grade stones with hints of a very faint or light yellowish or brownish color. The color scale proceeds with a right to Z.



Diamonds graded D through F are normally the most important and desirable because of their rarity. Such a diamond is a treat for the eyes of anybody. Be that as it may, you can, in any case, get an appealing diamond that is graded slightly less than colorless. Furthermore, diamond graded G through I show virtually no color that is visible to the untrained eye.

In the event that your setting is white gold or platinum, you may wish to settle on a higher color grade than if the setting is yellow gold.

And keeping in mind that a trace of yellow will be clear in diamonds reviewed J through M, this color can often be minimized by carefully selecting the right jewelry in which to mount your diamond. Remember that, while a great many people endeavor to purchase the most colorless diamond they can manage, there are numerous individuals who really lean toward the warmer glow of lower color diamond.



The extent to which the inclusions present in the diamond affects transparency the greater the clarity of the diamond, the rarer it is. Since natural diamonds are made under an inconceivable measure of weight and not developed in a research facility, it’s nothing unexpected that most diamonds have flaws.

Internal features and inclusions may light transmission through a diamond, decreasing its brilliant and its clarity. All characteristics  found  in or on a diamond can be divided into either :

  1. Internal characteristics: inclusions totally enclosed by the host diamond and those react for the surface of the gem.
  2. External characteristics: Those that are found on the surface of the diamond but do not penetrate into the gem.

  • F (Flawless): The degree “flawless” of G.I.A describes a diamond, which has no internal or external flaws. Very rare, these diamonds come with a price tag to match their rarity.
  • IF (Internally Flawless): A diamond can only be termed loupe clean if an expert examines it with a 10x loupe in normal light and it is found to be absolutely transparent and free from inclusions.
  • VVS1-VVS2 (Very Very Slightly Included 1 and 2): This term describes cut diamonds which when viewed through a 10x loupe by an expert show only a very – very small inclusion, which is very difficult to be seen.
  • VS1-VS2 (Very Slightly Included 1 and 2): Typical inclusions are easy to find out 10x magnification.
  • SI1-SI2 (Slightly Included 1 and 2): Small inclusions are easy to find out under 10x magnification.SI 2 stones may disclose inclusions to the naked eyes when viewed through the pavilion side.
  • I1-I2-I3 (Included 1, 2, and 3). Inclusions, which are obvious when viewed under 10x magnification as well as to the human eye.
  • GIA certificates incorporate what is known as a “plot” of a diamond’s inclusions — consider it a “diamond finger impression.” Since no two diamonds are the very same, contrasting the uniqueness of your diamonds clarity qualities with the plot gave on the diamond certificate offers affirmation that the diamond you pay for is a similar diamond you get.


While Flawless diamonds are the rarest, a diamond does not need to be impeccable to stunning.

  • Indeed, until you drop to the “SI” and “I” grades, a diamonds clarity grade affects the diamond value, not on the unmagnified diamond’s appearance.
  • a diamond with VVS and VS grades are superb decisions for both value and appearance.
  • Progressively reasonable (and still an incredible decision) are those diamonds which gemologists call “eye-clean” – diamonds without any inclusions noticeable to the naked eye. These diamonds are frequently found in the SI1 and SI2 and except if the beneficiary conveys a 10X loupe (a solid gems magnifying glass), she won’t see the considerations.
  • As to I1, I2, I3? Perhaps when there’s a diamond grade that is characterized as should be obvious ” you can see the flaws just by looking at the diamond,” nothing more should be said.
  • To be reasonable, not every person sees even unmistakable defects in a diamond. What’s more, not every single “visible” flaw is “equally” visible.


A carat is a unit of weight. It is how much gemstones weighs, like grams, pounds, and ounce. This value is the only objective one. It determines the size of a diamond, the appearance, but not necessarily the quality.

Frequently when individuals hear the expression “Carat Weight,” they think it alludes to the size of the diamond. In fact, Carat alludes to the weight of the diamond, not how large the stone is. A 1 Carat Diamond equals 200 milligrams or 0.200 grams. Contingent upon Diamond’s Shape and how it is cut, two 1 Carat Diamonds may be very unique in size While Carat weight is a component to think about when purchasing a diamond, the general appearance and brilliance should convey more significance. For example, a fair 1.5 Carat diamond won’t sparkle as brilliantly—or draw as much consideration—as a dazzling 1.0 Carat diamond, regardless of the amount more it weighs.

NOTE: “Karat” is an alternate word that is used to depict the purity of gold.



Decide your financial plan. You will hear different rules, for example, “the wedding ring should cost 2-3 months compensation”, however, a superior thought is the thing that can be managed. Choosing carat measures is extremely about striking a balance between size, quality, affordability, and individual inclination. In the event that she favors larger jewelry items, and you are working inside a financial plan, you can at present locate a bigger diamond of fantastic quality diamond by choosing one which is graded somewhat lower as far as color and clarity.

Keep in mind that thin fingers make little diamond look greater. On the off chance that she has little fingers, a 1-carat diamond will look proportionately substantial — and a considerably bigger stone may show up stunningly big.
