The Four C’s:

There are many factors that influence the price and grading of a diamond. The most commonly quoted of these are the Four C’s; Cut, Colour, Clarity and Carat. Our diamond experts will guide you in choosing the best combination of these to suit not only your design but also your pocket.


The first factor that influences a diamond’s price Ideal cut3is the cut of the stone. In most cases, round brilliant cut diamonds are more expensive than princess cut diamonds and badly cut stones are in general sold at a higher discount percentage from the lapidary or graded lower and thus sold at a better price. A well-cut diamond exhibits certain characteristics which ultimately influence its appearance.


A diamond’s colour can be graded in various ways. The most commonly used system nowadays (also used for clarity) is the GIA (Gemological Institute of America) system. In the GIA colour grading scale for white and yellow stones the scale starts at D, which is completely colourless, and carries on down the alphabet right up to the fancy yellows which start at about R (depending on the colour distribution of each particular stone) to Z. The most economical colour range for white stones lies between I (for settings in white gold) and L (for settings in yellow gold). From L downwards the colour starts becoming noticeably yellower and from the fancy yellows down the price once again starts climbing.




In the GIA diamond grading system the highest grade that can be given to a diamond is FL (Flawless). FL is only awarded to diamonds that have absolutely no flaws, either internal or external.


Next is IF (Internally Flawless) which means that the stone has no flaws on the inside, but may have some lapidary mistakes or naturals on the surface. These are NEVER visible with the naked eye and can only be spotted under 40X magnification by a trained eye.


VVS (Very, Very Small inclusion) is awarded to diamonds with some inclusions/faults/marks on the in- or outside of the diamond, but which is not visible with the naked eye. These can be spotted under 40X magnification and sometimes with a 10X loupe by a trained eye. The level is subdivided into two, sometimes three more grades; VVS1, VVS2, VVS3, to accommodate higher and lower grades within the level.


VS (Very Small inclusion) is usually a diamond with inclusions that are visible under 40X magnification, under a 10X loupe and sometimes to the highly trained naked eye. This level is also subdivided into two, sometimes three grades; VS1, VS2, VS3, to accommodate higher and lower grades within the level.


SI (Small Inclusion) is a diamond of which the flaws can easily be found with any kind of magnification, are visible to the trained naked eye and sometimes to the untrained naked eye, depending on the nature of the inclusion, where in the diamond it is situated and the sub-grade. As with VVS and VS, SI also comes in two, sometimes three subdivisions; SI1, SI2, SI3.


I (Included) is a stone of which the inclusions will be visible even to the untrained naked eye. These are usually stones with large cracks or cleavages, carbon inclusions or included crystals. Depending on where in the stone the inclusion lies, they are usually highly visible and are not recommended for use in jewellery since besides for the obvious aesthetical problems, they are also a risk for cracking, chipping or breaking during setting or general wear. The I level is also subdivided into I1, I2, I3.


2014-04-25 14.04.58Carat is the unit of weight measure used to measure the weight of a diamond and other gemstones. It is not to be confused with Karat, which is the measure of gold content within an alloy. One carat (1.0 ct) is equal to one-fifth of a gram (0.20 g). Each carat is subdivided into 100 points (0.01ct to 0.99 ct).

This next section is a little long winded, but it might help you understand what your dealer is saying.

When a dealer expresses the weight of a diamond as a “one-carater”, he is talking about a stone with a weight higher than 1.0ct (usually between 1.0ct and 1.1ct). When the dealer refers to a diamond as a “one-pointer”, he is in fact referring to a diamond with a weight of 0.01 ct. There is no range when talking about stone below twenty points (0.20 ct) since the difference in weight at that size makes quite a large difference to the diameter of the stone. Knowing this it is easier to deduce that a half-carater would be a stone in the region of 0.50 ct and a half-pointer would be a stone with a weight of exactly 0.005 ct. When we are speaking of a stone weighing for instance 0.30 ct, we could express it as either a “thirty pointer” or a “zero point three carat”. The same applies to any diamond lower than 1.0 ct and can also include numbers after the decimal. A 0.64 ct diamond could be referred to as a “sixty four pointer” or a “zero point six, four carat” and a 0.92 ct diamond could be named a “ninety pointer”, a “ninety two pointer” or a “zero point nine, two carat” and so forth. Usually a diamond with a second decimal that lies within 3 points of a rounding the first decimal could be expressed by rounding it up or down to the nearest first decimal, as demonstrated in the example of the 0.92 ct diamond. When a diamond is certified, however, the actual weight of the stone (ex. 0.923 ct) is recorded on the certificate. The precise weight of a diamond can only be determined by weighing it (out of setting) on a carat scale, but for insurance valuations the weight is usually determined by formula.


Certifying a diamond and grading / evaluating / valuating / supplying a document stating that it is in fact a diamond and or its grade is not the same thing. Certificates (see example) can only be extended by qualified gemologists at registered laboratories (always for loose stones only), usually (but not always) come in the shape of a smallish plastic pouch with a card and a folded diamond parcel and are usually only awarded to diamonds with a weight greater than 0.20 ct (the weight restriction is entirely the prerogative of the laboratory for newly produced stones, or the client, should they wish to send their own loose stones in for certification, at a charge). Each certificate contains the weight, cut as well as the colour and clarity (as graded by the laboratory) of each stone, a certificate number and comments by the gemologist, should he/she find any oddities like resin filled cracks, colour over tones etc.

On the inside of the certificate you will find a plotting of all flaws if any are present, a table marked by the gemologist stating the grade once more and a folded diamond parcel once again stating the grade and containing the actual stone.

Inside the diamond parcel you will usually find (apart from the stone) an adhesive label stating every possible measurement and percentages of its proportions for comparison to the Ideal Proportions.

Only this is regarded as an accurate grading and only this can be refered to as a “diamond certificate”. Everything else (in the case of valuations for insurance purposes) is at best calculated and informed guesswork from the professional in question. When a new uncertified diamond is bought, the dealer will supply the actual weight and approximate grade of the stone to the manufacturer, who can then record it on the first valuation certificate issued in which he/she guarantees that the diamond used is, first and foremost, an actual diamond and the approximate grade of the stone on a document containing the manufacturer’s letter head and details. All our staff has completed diamond grading courses endorsed by the Jewellery Council of South Africa and are therefore qualified to determine the approximate grade and value of most diamonds. We supply diamonds with and without laboratory certificates depending on the preference of each client, since stones under 0.10ct are almost never physically certified and certified stones under 0.20ct are usually quite a bit more expensive. We do, however, guarantee that our diamonds are all graded and tested conflict free natural diamonds from local mines subscribing to the Kimberley Process.This we will state on each valuation certificate issued for newly manufactured items containing diamonds bought from us.
