Diamond Quality

Understand Your Diamond Quality

Just like people, diamonds are intriguing and complex. No two diamonds are alike, even if they carry the exact same technical criteria. The beauty of the diamond is judged using a universal measure that examines a gemstone’s 4Cs: cut, colour, clarity and carat.


Cut is the most important out of the four Cs. It refers to how well- proportioned the dimensions and precision of the cut, which determines its ability to handle light that creates brilliance and scintillation.


Diamond Clarity refers to the Inclusions and Blemishes in a Diamond. Diamonds can have internal characteristics known as inclusions or external characteristics known as blemishes. Diamonds without inclusions or blemishes are rare; however, most characteristics can only be seen and less visible the inclusions, the higher the clarity grade.


Colour is one of the attributes of a diamond. A diamond colour grade is based on the absence of colour. The value of a diamond is based on its being colourless, colourless being the rarest of them all. The industry standard for grading colour is to evaluate each stone against a master set assigned with a letter grade from ‘D’ (colourless) to ‘Z’ (light yellow).


A key factor in a diamond’s evaluation is weight, measured in metric carats (CT). Naturally, diamond prices increase with carat weight due to its rarity and desirability. However, diamonds of equal carat weight can have very difference values, and prices.
