The Five C's

So how do you distinguish one Diamond from another?

What makes one gem more valuable than its apparently 'identical' looking twin?

Every Diamond is unique - no two diamonds can ever be the same - it's just the way nature intended and it's what makes these precious creations so amazing.

1. Cut

Most Diamond purists agree - it's 'the cut' that has the greatest impact on a Diamond's beauty and allure. The more precise and skilful the cut, the more appealing the gem is to the eye.

What is Diamond Cut?

Diamond Cut refers to the quality of how a diamond is cut and polished. The diamond cut evaluates the proportions, depth, and symmetry of a diamond rather than its shape, such as pear or round. Therefore, cut is not only focusing on how the diamond was cut, but also the physical shape of the diamond. A well-cut diamond sparkles and reflects light, but a poorly-cut diamond is dull. Diamonds are graded on a scale from excellent to poor, after experts examine their cut. The symmetry, polish, brightness, sparkle, and fire of a diamond determines its rank on this scale. When buying a beautiful diamond, the certification of Cut Quality is vital.

2. Colour

Colour is a very personal thing, and there are many details to consider when deciding on the right colour Diamond for you.

What is Diamond Colour?

Diamond colour refers to how clear or yellow a diamond is. C coloursless diamonds are the most valuable, while yellow diamonds are less precious. Experts use a scale to determine the colour of diamonds. The highest grade on this scale is D (colourless), and the lowest grade is Z (light yellow or brown). This colour grading has an influence on a diamond's pricing. The colour of a diamond is important as the more colour present, the less light is reflected.

3. Clarity

The Clarity of a Diamond is most commonly known as 'nature's fingerprint' or 'birthmark'.

What is Diamond Clarity?

Diamond clarity is a qualitative metric for grading a diamond's appearance. The inclusions and imperfections in a diamond determine the clarity grade. A diamond's clarity grade has a significant impact on the price.

Diamond Clarity Charts are used by experts to display the grade of a diamond on a scale. Internally Flawless (IF) is the highest grade on this scale. This grade is determined by experts examining the diamond with and without microscopes. The size, nature, number, location, and relief of imperfections influence the grade. Relief refers to the noticeability of inclusions in comparison to the entirety of the diamond.

4. Carat

It's a popular misconception, but the carat of a Diamond is actually a measure of its weight, not its size. This weight measurement directly impacts the price point of a ring.

5. Confidence

Confidence is the fifth but most vital C. Buying a diamond is a joyous and unforgettable occasion. Knowing everything there is to know about diamonds will help you select a diamond you will cherish for a lifetime.
