 Diamonds – Cut | Clarity | Colour | Carat



The cut or ‘make’ of a stone is one of the most important of all diamond characteristics because it determines its brilliance. It refers to the angles and proportion of a diamond, as well as its polish and quality of faceting. Often the cut of a diamond is incorrectly referred to as the shape (round, square, marquise, etc.)


Well-cut diamonds reflect light from one facet to another and disperse and reflect this light through the top of the stone. Diamonds that are cut either too deep or too shallow can lose light through the sides and bottom, will be less brilliant and ultimately of less value.  We buy all our diamonds direct from the very best diamond cutter in Antwerp. Only diamonds with perfect cut and symmetry meet our standards. Selini diamonds are simply the finest money can buy.


Most diamonds have natural identifying characteristics referred to as inclusions. Clarity describes the presence or absence of inclusions within the diamond. The less inclusions a diamond has, the more valuable it is.

It should be noted that many inclusions cannot be seen cannot by the naked eye. It is not possible, without the aid of a 10x microscope, to see the difference between an IF (internally flawless) diamond and a VS2 diamond but it is possible to see the inclusions in an SI2 quality diamond if you look carefully with the naked eye.


Diamonds act as prisms and can divide light into a spectrum of colours and reflect this light as colourful flashes referred to as fire. The more colorless a diamond is the more colourful the fire will appear.

There is a grading system used for colours, the closer to colour D the more valuable the diamond. As the grade moves towards Z, colour increases and value decreases.


A diamond’s weight is measured in carats and is not an indicator of size. The word carat is derived from the Greek word  kerátion, or carob seed. It has been said that in ancient times people used the carob seed as a unit of measurement because each seed weighed consistently the same. These views have since changed, but nevertheless the name has remained. Today a one carat diamond is equal to 200 milligrams (0.2 grams) and is divided into 100 “points”. Thus a 3/4 ct diamond is 75 points or 0.75 carats.


A diamond’s carat weight is the most significant pricing determinant for diamonds. It is important to understand that as a diamond’s carat weight increases so does it’s value per carat. In fact, a diamond’s price rises exponentially with its carat weight. For example, a diamond that is double the size of another diamond can be priced up to 4x’s higher than the other diamond. Since this has long been understand by the diamond industry, many diamond cutters use this to their advantage and purposely cut diamonds to maximize their carat weight. Unfortunately, often times these diamonds are cut to poor proportions and offer less brilliance than a superior cut stone.

Popular carat sizes are usually 0.50ct, 0.75ct, 1.00ct, 1.50ct and 2.00ct.
