In the entire globe the diamond used for jewellery making is characterized using 4Cs. The concept of 4Cs was established in the 20th century by gemmologists of the Gemological Institute of America in 1953. These gemologists declared the characteristics under these 4Cs as the descriptor of diamonds. Now it is applicable and religiously followed all over the globe. The categories of 4Cs are:-

Carat:- The carat is the unit which is used to measure the mass of the diamond. The value of one carat is 200 mg. For diamonds of less than one carat, point unit is used which is equal to one one hundredth of a carat. The price of diamond is directly proportional to the number of carats in it. More weight if diamond is equal to more expensive diamonds. However, it is not at all necessary that the price per carat will increase linearly.

At times, there can be very steep and sharp jumps. There is a particular term in terms of carat which is used very frequently when purchasing solitaire diamond specifically which is total carat weight. This total carat weight is also very frequently used for necklace, bracelets and other similar jewellery pieces. Total carat weight is used to describe the total mass of diamonds or other gemstones in a piece of jewellery.

Colour:-  Coloured diamonds look spectacular, there is no second thoughts about it. But, the finest ones are colourless. These are termed as D colour diamonds across the globe. Following this comes the next trace which holds the very little amount of colour. 

This one can be observed only by a very recovery diamond valuer. It is categorised under E colour or F colour. Going further, the next categorisation of diamond are termed as G or H colour diamonds. Slightly coloured diamonds are called I or J or K colour.

Though a diamond can be found in any colour, however, the purest form is transparent with no colour at all. The number of impurities present in the diamond contributes to a great extent to the kind of colour exhibited by the diamond. The colour component of the diamond can both increase and decrease its value.

 The diamonds that are used as gemstones are usually light in colours with just a tint of colour in them. In terms of diamond structure, the most common type of impurity is nitrogen, due to which range of colour ranges from yellow to brown.


Clarity is the measure of the internal defects called inclusions. The more high is the clarity, the rarer the diamond becomes.

Cut:- This is both an art as well as a science. In this, a clean-cut is important. A diamond that is cut clean is much more brilliance than a diamond that u energies a dirty cut. The cut of a diamond describes how it can be cut and polished.

For each kind of cut, there are specific guidelines for each length, breadth and angle. The technique for diamond cutting was developed centuries ago in 1919 by mathematician and gem enthusiast Marcel Tolkowsky. The exact round brilliant has approximately 57 facets.
