Rough diamonds do not sparkle. Only by cutting the stone can the sparkle appear. In the 14th century, German diamond cutters began cutting the upper facet, the so-called 'table' of the diamond. When, in 1456, Lodewijk van Bercken (Bruge, Belgium) developed a cutting technique based on diamond dust, people began to cut in tiers and the craft of diamond cutting truly took shape. The facets (57 or 58 for the brilliant cut shape) provide the intense brilliance and bring out the fire.
