How do you assess the quality of a diamond?

How do you assess the quality of a diamond? That is a question many ask themselves when considering investing in a gemstone—whether it’s for an engagement ring, a piece of jewelry for a special anniversary, or a gift for a loved one.

At Viclara, we understand that it can seem like a complex decision. Our mission is therefore to make it easy and secure for you to navigate the world of diamonds—with both professional knowledge and aesthetic understanding at the center.

The Four Cs – the foundation of diamond quality

When evaluating the quality of a diamond, it is crucial to understand the so-called 4 Cs: carat, cut, clarity, and color. These four elements form the cornerstone of professional diamond assessment and have a significant impact on price, appearance, and value.

By knowing the 4 Cs, you gain a clear picture of what lies behind the beauty of a diamond—and you become better equipped to make a choice that reflects your wishes and your style.

Carat – weight that matters

Carat indicates the diamond's weight. One carat equals 0.2 grams. It’s easy to believe bigger is always better, but in reality, shape and cut also play a major role in visual impact.

At Viclara, we emphasize the balance between carat, proportion, and design. A well-proportioned diamond with slightly fewer carats can often appear more impressive than a heavier stone with less brilliance.

Cut – the dance of light

Cut, or craftsmanship, refers to the diamond's proportions, symmetry, and polish—not its shape. This characteristic determines how light is reflected through the stone, and thus how much it sparkles.

A precise cut highlights the diamond’s brilliance and fire. We focus on exactly this quality, as it enhances the uniqueness of each stone and creates the visual expression that brings a piece of jewelry to life.

Clarity – beauty from within

Clarity describes the diamond’s internal and external purity. Most diamonds contain microscopic inclusions—nature’s own fingerprints on each individual jewel.

The scale ranges from "Flawless" to "Included," and the choice depends on both budget and preference. Many inclusions are invisible to the naked eye, and at Viclara we help you find the clarity that matches your wishes and offers the best value for your money.

Color – from cool elegance to warm glow

A diamond’s color is assessed on a scale from D (completely colorless) to Z (with a distinct yellow or brown hue). Colorless diamonds are rare and therefore more sought-after—but often it’s the subtle nuances that add character and depth to a piece of jewelry.

At Viclara, we advise you based on both personal preference and the impact of light—so the color underlines both your style and expression.

Certification – your assurance of quality

No matter how a diamond is evaluated according to the Four Cs, it is important to ensure the assessment is made by an independent and recognized authority. Certification serves as documentation of the stone's authenticity and qualities.

We exclusively offer certified diamonds at Viclara, typically from GIA or IGI, so you have complete transparency and peace of mind with your choice.

The whole – where intuition and expertise go hand in hand

Even with knowledge of carat, cut, clarity, color, and certification, the final choice is often intuitive. It’s about how the diamond feels. Do you see fire and life in it? Does it speak to you?

The goal is not to find the “perfect” diamond on paper—but the stone that feels perfect to you. At Viclara, we guide you with professional insight and personal sensibility, so you choose with your heart and get a piece of jewelry to accompany you for many years.
