How to select your diamond:-

There are four characteristics that determine the quality of a diamond.
Cut, colour. Clarity and carat/weight.

Cut:-
Many people confuse cut with the shape of a diamond. Most diamonds are cut with a full 58 facets and a good cut or make has more brilliance, fire and ultimate beauty. However, the shape you select is a matter of individual taste and today your choice is only limited by the skill and imagination of the craftsmen.

Colour:-
The most sought after colour for a diamond is one where no colour is evident.
It is the totally colourless diamond that acts like a prism, allowing light to pass effortlessly through to be transformed into a rainbow of colours. While the majority of gem diamonds appear to be colourless, others can contain increasing shades of yellow to brown, some of which are referred to as champagne diamonds. Other diamonds of exceptional colour, red, blue, pink and amber are known as “fancies”.

Clarity:-
Diamonds, more than any other gemstone have the capability to produce the maximum amount of brilliance. While almost all diamonds contain minute traces of non-crystallized carbon or small non-diamond crystals, one that is virtually free of interior or exterior inclusions(commomnly called flaws) will be of the highest quality. In such a diamond nothing interferes with the passage of light through it. Thus it clarity only serves to intensify its beauty and fire.

Carat/weight:-
As with all precious stones, the weight and therefore the size of a diamond is expressed in carats.
One carat is divided into “100 points” so that a diamond of “25 points” is described as a quarter of a carat or 0.25 carat.
Size is the most obvious factor in determining the value of a diamond but now you know that two diamonds of equal size can have very different values depending on their quality.
