The original Asscher Cut was created in 1902 by Joseph Asscher, a jeweler who was so trusted in his day that he cut both the Excelsior diamond and the Cullinan diamond, two of the largest and most famous diamonds ever discovered.
Almost 100 years after this master jeweler created the original Asscher cut, his descendents, Edward and Joop Asscher, utilized modern techniques and technology to create its successor, the Royal Asscher Cut. Years of extensive research, computer modeling and simulation resulted in an Asscher cut diamond that is perfectly symmetrical, with every facet measured distinctly to ensure absolute precision. The cut features a high crown and 74 facets compared to the 58 of the original Asscher cut.
Many companies use the term "Asscher" to refer to square emerald cut diamonds that rarely meet the strict requirements set forward by Joseph Asscher in his original cut and never match the brilliance of the internationally patented Royal Asscher cut.
