Jeder Diamant ist Einzigartig

Keine zwei Diamanten sind gleich. Jeder Stein hat individuelle Merkmale, die seine Schönheit und Ausstrahlung besonders machen.

To evaluate these differences objectively, recognized gemological laboratories such as the GIA (Gemological Institute of America) or the IGI (International Gemological Institute) use an internationally recognized system. This evaluates diamonds based on the so-called 4C criteria: Cut, color, clarity and carat weight.

These four characteristics significantly determine the quality and value of a diamond. If you understand them, you can make the right choice - for a stone that is not only visually impressive, but also represents a valuable investment.

It is particularly important to rely on these quality features when buying online. After all, many details that influence the price and beauty of a diamond are barely recognizable in photos. An official certificate with a clear rating offers the necessary security here.

Below we explain what you should look out for in each of these four features:

CUT

Der Schliff eines Diamanten beschreibt das Zusammenspiel von Proportion, Politur und Symmetrie und ist entscheidend für sein Funkeln. Nur ein präzise geschliffener Stein reflektiert das Licht optimal und sorgt für maximale Brillanz und Feuer. Ist der Schliff zu flach oder zu tief, entweicht das Licht, der Diamant wirkt stumpf. Daher führen wir bei Stellini Diamonds ausschliesslich Steine mitausgezeichnetem (Excellent) Schliff.

COLOUR

The color of a diamond describes how colorless or tinted it is - the clearer, the more valuable. A yellow or brown tint usually reduces the brilliance and therefore the value of the stone. Colorless diamonds allow light to pass through better and sparkle more intensely. Lab-grown diamonds often have a particularly pure color, as there are hardly any interfering trace elements during the creation process. The color scale ranges from D (very fine white) to Z (tinted). At Stellini Diamonds, we only stock the best quality diamonds in colors ranging from D to F (colorless)

Clarity

Clarity describes how free a diamond is of inclusions. The fewer such impurities there are, the higher its quality and value. Many inclusions are only visible under 10x magnification, but still influence the valuation. The clarity is divided into eleven levels - from loupe clarity (FL) to strongly included (I3). Every diamond is unique, and small inclusions often make it even more individual and full of character. We only stock diamonds from VS.

CARAT

Karat ist die Masseinheit für das Gewicht eines Diamanten nicht zu verwechseln mit seiner Grösse. Denn je nach Schliff kann ein Stein mit gleichem Karatgewicht unterschiedlich gross wirken. Die tatsächliche Grösse wird daher zusätzlich in Millimetern (Länge × Breite) angegeben. Grundsätzlich gilt: Je schwerer der Diamant, desto seltener und wertvoller besonders bei natürlichen Diamanten, deren Gewinnung aufwendig und ressourcenintensiv ist.
