Because a Diamond is More Than a Sparkle — It’s a Story. Yours.
When you’re choosing a diamond, you’re not just picking a stone. You’re selecting a symbol of commitment, legacy, and once-in-a-lifetime moments. At Zermatt, we believe you deserve to make that choice with clarity and confidence.
That’s why we walk you through the 4Cs of diamonds — the global standard for diamond quality. But we’ll make it make sense for you, not just for gemologists.
Cut
The most important “C”. A diamond’s cut determines how brilliantly it reflects light. More than just shape, it’s about craftsmanship: symmetry, proportions, polish. A well-cut diamond will light up a room before you even notice the size.
Colour
Diamonds are graded from D (colourless) to Z (noticeable yellow tint). Colourless diamonds are rarer and more valuable, but certain warm tones can be charming depending on personal style and setting choice.
Clarity
Clarity refers to the tiny inclusions and blemishes formed during a diamond’s creation. Most are microscopic and invisible to the naked eye. Think of them as birthmarks that make each diamond unique.
Carat
Carat weight measures the diamond’s size, but bigger isn’t always better. The magic lies in proportions, cut quality, and how the diamond presents itself on the hand.
The 4Cs, Demystified
What’s the most important “C” when buying a diamond?
Cut. Every time. A perfect cut makes your diamond dazzle. You can compromise slightly on colour and clarity, but never on cut.
How do I balance the budget with diamond quality?
We help you navigate the sweet spot. For example, you can opt for a slightly lower colour grade if it’s well-cut and set in yellow gold. The brilliance will still turn heads.
Are inclusions a bad thing?
Not necessarily. Most inclusions are invisible to the naked eye and have no impact on beauty or durability. We’ll ensure you get an “eye-clean” diamond that looks flawless where it counts.
Does carat size affect price the most?
Carat does impact price, but not as much as cut and clarity at certain levels. Two diamonds of the same carat can look very different depending on proportions and cut quality.
