In 1902 the Dutch diamond cutter Joseph Asscher developed the cut that would carry his name on into the future. The square, step-cut, design had been around for ages but the modifications Asscher implemented, two more rows of facets and a diagonal cross-cut blunting the corners of the square, made the Asscher into a design that could be patented. This high-crowned diamond cut, with perfect symmetry and 74 facets loses an additional 15% of the rough weight in order to gain the greater dispersion and brilliance associated with an Asscher cut.
In 1980 Queen Juliana of the Netherlands awarded a royal title to the Asscher Diamond Company thus changing its name to the Royal Asscher Diamond Company and its patented cut to the Royal Asscher Cut.
