The clarity of a diamond is a key quality characteristic and describes how free the stone is from inclusions (internal features) and surface characteristics. These natural features form during the diamond's creation and make each stone unique. The fewer inclusions present, the rarer and usually more valuable the diamond is.

What are inclusions in diamonds?

Inclusions are natural features inside or on the surface of a diamond. These include small crystals, dots, clouds, or fine lines (feathers). The evaluation is done internationally under 10x magnification. Many inclusions are not visible to the naked eye in everyday life, especially in well-cut diamonds.

International clarity grades

• FL (Flawless) – flawless, no inclusions
• IF (Internally Flawless) – no internal inclusions
• VVS1 / VVS2 – very, very small inclusions
• VS1 / VS2 – very small inclusions
• SI1 / SI2 – small inclusions, partially visible
• I1 / I2 / I3 – obvious inclusions

How does clarity affect appearance and price?

Diamond clarity directly influences the price. At the same time, a diamond does not have to be flawless to appear high-quality. Especially with a good cut, inclusions are barely noticeable visually. Therefore, clarity should always be considered together with cut quality, color, and carat weight.

Diamond cut shapes: overview and differences

The cut shape determines the look of a diamond and influences how much it sparkles. Besides the shape, the cut quality is also crucial for brilliance. While the cut shape defines the appearance (e.g., round, oval, or square), the cut quality describes how precisely a diamond is proportioned, polished, and symmetrically crafted.

Why are cut shapes important?

Different cut shapes affect not only the appearance but also how a diamond reflects light. Especially brilliant cuts (e.g., round brilliant or radiant cuts) create intense sparkle because many facets reflect the light back. Step cuts (e.g., emerald or asscher cuts) appear calmer and more elegant but often show internal features more clearly due to their large, open facets.

The appearance on the finger can also differ significantly: elongated shapes like oval, marquise, or pear shape often make the diamond look larger and visually elongate the hand. Angular shapes like princess, radiant, or asscher appear modern and clear. The cut quality is also decisive: a precise cut ensures more brilliance, better light performance, and an overall higher-quality effect.
