The Laings Journal
Diamonds are one of the earth's most precious creations and today are used as symbols of love, commitment, and triumph. In the middle of the twentieth century, GIA developed the first classification system for describing diamonds, which is now accepted and adopted worldwide. We are here to make learning about these gemstones easier as we talk you through the 4Cs of diamonds — Cut, Colour, Clarity and Carat Weight.
When purchasing diamonds, whether it be diamond rings, earrings or other diamond jewellery, it is essential to understand what to look for in the gemstone's characteristics.
Why is diamond cut important?
We often think of a diamond's cut as its shape (round, princess, pear, oval), but what it actually refers to is how well the diamond is cut in order for the facets to interact with the light in the best way. The sparkle of a diamond is determined by its proportions, symmetry and polish. Therefore, the cut is deemed the essential factor in ensuring the desirable brightness, fire, and scintillation in a diamond.
The cut of a diamond is graded from poor to excellent. When viewing the diamond through a proportion scope from the top, you should see eight perfectly formed arrows - this indicates an excellent cut. When viewing from the bottom, you should also see eight perfectly formed hearts.
Why is the colour of a diamond?
When discussing the colour of a diamond, we are actually referring to the absence of colour. The perfect diamond will have no hue and will resemble a drop of clear water.
The colour-grading system from D to Z measures the degree of colourlessness in a diamond, beginning at D (colourless) and ending at Z (light colour). At Laings, we typically work with diamonds that are near colourless and above. Differences in colour are so subtle, yet a significant factor in determining the value of your stone. Therefore, it is essential to have your diamond graded by expert gemological institutes.
What is diamond clarity?
No two diamonds are the same, and we begin to learn about our diamonds unique personality when we look into its clarity. Clarity refers to the absence of inclusions, which are natural birthmarks in a diamond that occur during its formation.
Whilst extremely rare, the diamond clarity grade begins at flawless, referring to stones that have no visible inclusions under a 10x magnification. The scale ends at included where inclusions are clearly visible under a 10x magnification.
What is the importance of diamond carat weight?
The carat weight refers to the weight of the diamond and is not to be mistaken by the size. You may hear the carat weight being referred to in points. One carat is made up of 100 points, and therefore a 0.55 carat stone would be referred to often as fifty-five points.
The 5th C - Certificate
It is often said that there is an additional 'C' to consider - the diamond certificate. The certificate will break down the 4Cs discussed and give a detailed description of your diamond in reference to each. It is vital to have your certificate completed by an independent body, giving you peace of mind that your diamond has been graded in optimum conditions by a non-bias source. Most commonly, Laings work with the world renowned Gemological Institute of America (GIA) and the International Gemological Institute (IGI).
