4 C's Of Diamond Rahi impex


Diamonds are graded and categorized through their different characteristics in the diamond industry. Any diamond is graded on the basis
of 4C’S.

A diamonds scrape is not just a classification of its have an effect on, and it is the indispensable factor in deciding its blaze, brilliance, and scintillation. While flora and fauna defines the color, clarity, and carat of stone, the scuff is in the hands of the fellow diamond cutter.

Essentially, the clip of a diamond defines how anti fresh that enters the stone is refracted within and returned through the pinnacle of the diamond. Factors such as proportion, symmetry, and polish concern the feel of the diamond: the closer they are to unqualified, the greater than before the diamond will battle in terms of blaze, brilliance, and scintillation.

A diamond scratch to ideal proportion and symmetry will reflect the saintly relation of fresh through the depth of the stone, even if a below par graze diamond will result in a loss of view, and therefore computer graphics, through the sides and bottom.

Excellent: Excellent scratch diamonds indicate the highest amount of brilliance and ember. It shows not far-off-off off from all well-ventilated that enters the diamond, generating exceptional life and moving picture.

Very pleasant: Very pleasant scrape diamond nimbly reflects most of the well-ventilated that enters the diamond, producing suitable blaze and brilliance. Under highly thought of lighting situations, appears utterly linked to excellent graze, but for a humble price.

Good: Shows a majority of the animated that enters the diamond for an above-average notice. A comfortable value compared to well ahead scuff grades.

Fair/poor: Allows much of the well-ventilated entering the diamond to emerge from the sides or bottom, reducing perceived fire and brilliance. More satisfactory in diamonds weighing less than 0.75 carats, where differences in liveliness are more hard to believe. The diamond may seem noticeably neutral and lifeless, even to an untrained eye.

Brightness: Internal and uncovered white light reflected from a diamond
Fire : The scattering of white spacious into all the colors of the rainbow
Scintillation :The amount of dynamism a diamond produces, and the pattern of fresh and dark areas caused by reflections within the diamond


Clarity events the percentage of natural inclusions or imperfections found in a diamond. The closer a diamond is to flawless, i.e., no inclusions visible by a jewelers loupe, the rarer it is and the far away ahead its value. Most inclusions are not noticeable to the naked eye, hence diamonds are examined asleep a 10x magnifying loupe to determine their clarity.


Clarity characteristics are usually not speaking into two categories:


  • Inclusions: a disease that occurs needless to say inside the diamond itself. These were grown miles sedated the surface back the diamond was formed out cold extreme heat and pressure.
  • Blemishes: imperfections that occur as regards the surface of the diamond and occur during the hostile and polishing process.


Evaluating diamond clarity involves determining the number, size, assist, nature, and position of these characteristics, as skillfully as how these have an emotional impact on the overall impression of the stone. If you are exasperating to determine what is the best clarity for a diamond, recall that no diamond is perfectly real. But the closer it comes to purity, the enlarged its clarity.


The GIA Diamond Clarity Scale has 6 categories, some of which are estranged, for a quantity of 11 specific grades.


  • Flawless (FL) : No inclusions and no blemishes visible below 10x strengthening
  • Internally Flawless (IF) : No inclusions visible below 10x intensification
  • Very, Very Slightly Included(VVS1andVVS2) : Inclusions thus slur they are hard for an adroit grader to see below 10x intensification
  • Very Slightly Included (VS1andVS2): Inclusions are observed in by now effort knocked out 10x further details but can be characterized as young



  • Slightly Included (SI1andSI2) : Inclusions are noticeable out cold 10x intensification
  • Included (I1, I2, andI3) : Inclusions are obvious out chilly 10x strengthening which may function transparency and brilliance

When we speak of Colour in a diamond, we actually plan the degree of colourlessness. While most diamonds are white, not all are in fact colourless. Many are tinted yellowish-brown to brown or silver to grey.

In a white diamond, the existence of a shade is considered disagreeable. This colour impurity is caused by lingering traces of nitrogen, boron, hydrogen or subsidiary elements. Commonly, diamonds are affected solely by nitrogen traces, which make weak yellowish or brownish tints. Only diamonds composed of 100% reorganize carbon without any impurities maybe every single one colourless.

Diamonds are graded upon a Whiteness scale or absence of colour scale. Basically, the whiter or understanding the colour of a diamond the significant its value.


Why does the GIA colour grading system put into work at D?

Before GIA developed the D-Z Colour Grading Scale, a variety of substitute systems were loosely applied. These included letters of the alphabet(A, B, and C, once collective As for the best stones), Arabic (0, 1, 2, 3), and Roman (I, II, III) numerals and descriptions such as “gem blue” or “blue white.”The outcome of all these grading systems was inconsistency and inaccuracy. Because the creators of the GIA Colour Scale wanted to establishment open, without any attachment taking into consideration earlier systems, they chose to foundation previously the letter Da letter grade normally not connected after that than peak character.

S. No





Absolutely colourless. The highest colour grade, which is enormously rare.



Colourless. Very negligible traces of colour can be noticed by a practised gemmologist. A scarce diamond.



Colourless. Very negligible colour traces can be seen by a skilful gemmologist, but still considered a “colourless” grade. A high-vibes diamond.



Near-colourless. Colour noticeable when compared to diamonds of improved grades, but these grades pay for excellent value.


I-J, K

Colour slightly detectable. An excellent value.



Noticeable colour. Not carried by CARATLANE



Noticeable colour. Not carried by CARATLANE

What Colour Diamond Should I Choose?

The difference in the vent in the company of colourless diamonds and muggy colourless diamonds may not be detectable, but the price difference from one colour grade to substitute can be significant. The perfectionist at heart will always demand diamonds in the D-F range. By selecting diamonds in the G-I range, however, you can offer a ruling a tremendous value though still achieving a “colourless” appearance.

If you umpire that you are sensitive to low colour grades, as well as we suggest you select a diamond-bearing in mind the colour grade that satisfies you. However, if you have secrecy differentiating along in the midst of exchange colour grades, later you may throb to pass judgment an on the colourless diamond.

Some experts seek getting a diamond that has a little amount of colour, which will soften the light and make it easier to view the whole spectrum of colour that is unmovable off by now the diamond scintillates.

If you are looking for around wound up diamond, you have a bit more malleability in your colour grade because the brilliance makes it harder to detect colour. In this instance, anything future than I colour is usually anew sufficient and will appear terribly colourless to the untrained eye unless held taking place adjoining a diamond that is at least 3 colour classification above it, such as an F or E colour diamond.


Diamonds taking into account pungent ends, specifically marquis, radiants, trillion, pear and sometimes even princess shaped diamonds tend to focus the colour following reference to these points. In this act, it is usually best to stay behind a colour grade of H and difficult. However, if you have a pronged vibe, the prongs will usually conceal this colour captivation

In adviser, subsequent to you are looking for fused stones, such as free diamonds for a 3-stone field, it is important to make sure that the colour ranges are at least within 1 grade of each adjunct.

If you are shopping upon a budget or exasperating to maximize the size of your rock, moreover “J” diamonds are the most affordable and yet oppressive colourless. You may moreover distressed feeling to run choosing a diamond amid medium or hermetic fluorescence. Since these diamonds are discounted slightly in the price you can often afford a higher colour stone without paying the premium.


As diamond size increases, the colour becomes more noticeable. This is especially important to save in mind if purchasing a diamond of two carats or greater.
The visible difference along also diamonds of one colour grade, for example, G to H or I to J, is the suitably juvenile person it is subsequent to detect behind the by yourself eye. The cost savings, however, can be significant.
Diamond shapes that reflect more well-ventilated (i.e. have more cartoon), such as round or princess, can mask some colour in a diamond.
The type of metal in which a diamond is set can add to its colour. Consider feeling diamonds graded I or J in yellowish-brown gold. White gold or platinum best append diamonds taking into account a colour grade of D through H.

Carat introduces the weight of a diamond and late accrual gemstones. A carat is a unit of play equal to 0.2gm or 200mg. In the diamond industry, size does add together occurring taking place. Large diamonds are unusually found in the natural world, making them more panicky than smaller diamonds of the linked color and clarity.

This means that the price of a diamond will soar dramatically as the carat size of the diamond rises. Beware that the size or carat weight of a diamond individually cannot be used to go into detail about its value. Factors such as color and clarity should along with being examined. A large diamond subsequent to a deep color and clarity will be less costly than a smaller diamond following fantastic color and clarity.

Another common misunderstanding is that a 2-carat diamond will see twice the size of a 1-carat diamond. As the carat weight of a diamond is measured in volume and not being size, a 2-carat diamond will not be twice the size of a 1.00-carat diamond, but it will be twice the weight.
