The 4 C's

No two diamonds are alike, and that’s exactly what we love about this precious stone our hometown Antwerp is known for. Every diamond used in Wouters & Hendrix designs is hand-picked for its aesthetics and is guaranteed to have come from legitimate sources. The 4 C's—colour, clarity, cut, and carat weight—are the globally accepted standards for assessing the quality of a diamond.

At Wouters & Hendrix, we are committed to transparency and quality. With every jewel containing a diamond larger than 0,35 carats, we provide a gemological certificate from a recognized laboratory. This certificate outlines the 4 C's, offering you both assurance of the diamond’s authenticity and a deeper understanding of its exceptional quality, ensuring your jewel is as unique and enduring as your story

Carat

Carat denotes the weight of a diamond, not the size. One carat is equal to 0.20 grams. Diamonds with a larger carat weight are discovered far less often and so have a greater value per carat. Carat is the only one of the four C’s which is not subjective.

Cut

Cut refers to how a diamond’s facets interact with light. These facets are arranged with precise mathematical proportions to maximize a diamond’s fire and brilliance. A well-cut diamond reflects and refracts light internally from one mirror-like facet to another for maximum brightness and sparkle. 

Colour

Colour refers to the natural tint inherent in white diamonds. The colour is graded from D to Z. Completely colourless diamonds are graded D on the scale, and the colour gets progressively more yellow as it approaches Z. The more colourless the diamond, the more light passes through the stone and the livelier it is to look at. Natural diamonds also come in ‘fancy’ colours, and these are graded according to the intensity of their colour.  The more colour in the stone, the more valuable the diamond.

Clarity

Clarity refers to the purity and rarity of a stone. Inclusions are naturally occurring features formed deep within the diamond when it was first created. The clarity grade of a diamond is determined by the visibility and number and size of inclusions. It is graded from flawless to included.
