An Asscher cut is essentially a square emerald cut, with cropped corners and the same broad, step faceted structure. First cut in 1902 and revived through Art Deco design a century later, it remains one of the more architecturally distinctive shapes available today.

How It Differs From an Emerald Cut
Where an emerald cut is rectangular, an Asscher is square, with more dramatically cropped corners and a higher crown, giving it a distinctive, almost octagonal outline when viewed from above. Like the emerald cut, its broad open facets make clarity more visible, so a higher clarity grade is worth prioritising.
A Vintage Character, Deliberately
The Asscher's Art Deco associations make it a popular choice for buyers specifically seeking a vintage or heirloom aesthetic, rather than a contemporary one. It photographs with a distinctive geometric quality that few modern cuts replicate.
Best Settings for an Asscher Diamond
A four prong setting that protects the stone's cropped corners is standard. Because the shape is already visually bold, a simple band lets the stone's architecture do the work without competition from an elaborate setting.
