4Cs of the Diamond
Diamonds are natural stones and each diamond comes in unique internal and external characteristics. In addition to its size and colour, birthmarks inside the diamond also determine its characteristics.
The value of a diamond is based on the combination of these qualities. The four important characteristics that are used to classify a diamond are known as the “4Cs of the diamond”:Colour, Clarity, Cut and Carat.These characteristics are evaluated by diamond professionals and often documented in detail. This document is called grading report or diamond certificate.
Diamond certificates are important as they show the quality and the value of the diamond on your jewellery
Carat
To put it simply, diamond carat weight measures how much a diamond weighs. A metric “carat” is defined as 200 milligrams.
Each carat is subdivided into 100 ‘points.’ This allows very precise measurements to the hundredth decimal place.
A jeweler may describe the weight of a diamond below one carat by its ‘points’ alone. For instance, the jeweler may refer to a diamond that weighs 0.25 carats as a ‘twenty-five pointer.’
Diamond weights greater than one carat are expressed in carats and decimals. A 1.08 carat stone would be described as ‘one point oh eight carats.’
Cut
Diamonds in this range are on the top of the all grade settings and very rare due to perfect interaction of its facets and light. These diamonds reflect the light best and sparkle so intensely among all the diamond categories.
Diamond Clarity
This clarity scale is considered from flawless to internally flawless. These diamonds do not include any inclusions. Internally flawless diamonds may only contain faint external blemishes, which is removable by repolishing. Flawless and Internally Flawless diamonds are very rare.
Diamond Colour
D diamonds are the finest white and colourless; the rarest colour grades and have the highest value.
