The 4 C's of diamonds are the universally recognised standards for evaluating a diamond's quality and value. They stand for cut, colour, clarity, and carat weight. These criteria help determine the overall appearance and desirability of a diamond. Let's take a closer look at each of the 4 C's:
Cut: The cut refers to the proportions, symmetry, and polish of a diamond, rather than its shape. A well-cut diamond reflects light internally and externally, creating brilliance, sparkle, and fire. Cut grades range from Excellent, Very Good, Good, Fair, to Poor. The cut of the diamond can also refer to the shape, some of the most common shapes are brilliant cut (round), emerald cut, pear and oval.
Colour: The colour grading scale assesses the diamond's lack of colour. The highest grade, D, represents a completely colourless diamond, while grades progress in alphabetical order, with increasing presence of colour. The colour scale ranges from D (colourless) to Z (light yellow or brown). The most valuable diamonds usually fall in the colourless to near-colourless range (D to J).
Clarity: Clarity measures the presence of internal and external flaws, known as inclusions and blemishes, respectively. These natural characteristics are formed during a diamond's growth process. The clarity scale ranges from Flawless (no inclusions or blemishes visible under 10x magnification) to Included (inclusions visible to the naked eye). The higher the clarity grade, the rarer and more valuable the diamond.
Carat Weight: Carat weight is a measurement of a diamond's size. One carat is equivalent to 200 milligrams. However, carat weight alone does not determine a diamond's value. Other factors such as the cut, colour, and clarity also play a significant role in assessing a diamond's worth.
While the 4 C's are essential for evaluating diamonds, it's important to note that personal preferences and budget considerations also come into play. Each diamond is unique and finding the right combination of the 4 C's that suits your style and budget is key when selecting a diamond.
