The 4Cs of Diamonds

The Foundation of Diamond Quality

Every diamond is evaluated based on four essential characteristics, known as the 4Cs: Cut, Colour, Clarity, and Carat. Together, they determine the beauty and value of the stone.

  • Cut

    The cut defines how a diamond reflects light. A well-cut diamond captures light beautifully, creating brilliance and sparkle.

  • Colour

    Diamonds are graded from colorless to slightly tinted. The closer a diamond is to colorless, the rarer and more valuable it becomes.

  • Clarity

    Clarity refers to the presence of natural inclusions or imperfections within a diamond.

  • Carat

    Carat indicates the weight of a diamond. While larger diamonds are rare, true beauty lies in the balance between size, cut, and brilliance.

Diamond Shapes

A Reflection of Personal Style

The shape of a diamond defines the character of a piece. Each shape carries its own expression and emotional tone.

  • Round Brilliant - timeless, classic, and radiant
  • Oval - elegant and elongating
  • Emerald Cut - refined, minimal, and sophisticated
  • Pear Shape - unique and expressive
  • Princess Cut - modern with sharp brilliance

At LILOU VOIGT, sourcing rare shapes of identical quality and size is part of our craftsmanship - ensuring harmony in every design.
