The 4Cs Guide

Every diamond is graded on four characteristics — cut, colour, clarity and carat.

The industry loves to make these feel intimidating. They aren’t. Here is what each one actually means, and just as importantly, which ones your eye will notice and which ones you are mostly paying a grading chart for.

 

Cut — The One That Matters Most

Cut is not the shape of the diamond; it is how well the stone has been proportioned and finished.

A well-cut diamond returns light beautifully and looks alive. A poorly cut one looks dull even if its other grades are high.

Cut is the single biggest driver of how much a diamond sparkles — and the place we never compromise.

The Apekani Diamonds Standard: We select for Excellent or Ideal cut. This is where your money does the most visible work.

 

Colour — Spend Sensibly Here

Diamond colour is graded from D (completely colourless) down through the alphabet as faint warmth appears.

Here is the honest part: in the near-colourless range, the difference between one grade and the next is invisible to the naked eye, especially once a stone is set in gold.

The Apekani Diamonds Standard: We select for F–H colour. This range looks bright and white to the eye, particularly in a setting, without paying a premium for a difference you cannot see. Chasing a D when an F looks identical on the hand is exactly the kind of markup we built Apekani Diamonds to avoid.

 

Clarity — “Eye-Clean” is What Counts

Clarity describes tiny natural characteristics formed as the diamond grew. Most are microscopic. The practical question is simple: can you see anything with the naked eye? If not, the stone is “eye-clean,” and that is what matters for how it looks.

The Apekani Diamonds Standard: We typically select for VS clarity — comfortably eye-clean — so you get a flawless-looking diamond without paying for perfection only a microscope can detect.

 

Carat — Weight, not Size

Carat is a measure of weight, not how large a diamond looks. Two stones of the same carat can look different sizes depending on how they’re cut. It is also the C with the steepest effect on price. Our advice: decide your budget, prioritise cut, and let carat be the flexible variable — a beautifully cut, slightly smaller stone outshines a larger dull one every time.

 

The Apekani Diamonds Way to Read the 4Cs

Spend on cut. Be sensible on colour and clarity, because beyond a certain point you are buying a certificate, not a better-looking diamond. Treat carat as your budget lever. That is how you get the most beautiful piece for what you spend — and it is how we grade every stone we sell.
