Color

Colourless or white diamonds, most commonly known to the public, show no colour, at least at rst sight. When you look at them more closely, these diamonds can show a hint of yellow or brown. When the stones are compared to master stones, the exact colour of each diamond can be determined. The closer to absolute colourless a diamond is graded, the higher its value. Diamonds can be found in all the colours of the rainbow, from deep brown to warm yellow, lively pink to mesmerizing purple, intense red or deep blue. When diamonds show a vivid or intense colour, they are called ‘fancy colours’.

Clarity

As carbon crystallizes under immense pressure and heat for thousands of years, other elements than carbon can be included in the stone. These elements result in inclusions, from minimal traces, barely visible, to larger aws. The less inclusions a diamond holds, the higher the value. A stone that doesn’t contain any aws is extremely rare; it is called loupe clean. That explains why a loupe clean, smaller diamond will be signi cantly more valuable.

Cut

This characteristic refers to the shape in which a diamond is cut and the quality of the polished facets. Perfect proportions, excellent symmetry and an expert nish are the ingredients that turn a dull chunk of rough diamond into a dazzling diamond. Only then, the light can optimally travel through the diamond’s facets, creating that wondrous and enchanting luster.
