This diamond cut is also a rectangular shape, somehow similar to the emerald cut. It is also known as Hall of Mirrors due to the astonishing optical illusion and brilliance. This is the cut of the largest known diamond, the Cullinan Diamond, an unrivaled 3,205 carat diamond that belonged to British King Edward VII.
What makes the Asscher diamond shape unique is that there are not set numbers or strict guides to follow when cutting the stone. It depends on the cutter’s art to maximize the beauty and light performance of this squared diamond shape of 50 or 58 facets.
