Asscher Cut Diamond

Another name for this is Emerald Square Cut. It is known for its prismatic brilliance and unique shape with rectangular facetted pavilion. Main facet standard number related to this cut of diamonds is generally 58. Cut corners widths of Asscher Cut may vary. The tremendous luster associated with this diamond variety is due to its faceted culet, deep pavilion, small table, and high crown. This helps to create optical fascinating illusion known by the name of ‘Mirrors Hall’ effect.

Background & History

First introduced in 1902 by Asscher Brothers, they became highly popular during the 1920s after which their demand somewhat fizzled out. During this lull period, one could come across these diamonds only at the jewelry antique shops. Revival happened in 2002 when the shape made another comeback post its modification and adding more brilliance as compared to its traditional variety.

Contemporary Variety

The modern-day combination in the Asscher Cut makes it highly brilliant than regular Emerald Cut varieties. If well cut, it appears to contain concentric squares looking through the table, resulting from proper pavilion facets positioning underneath. Similar to Emerald Cut, Asscher Cut also comes with cropped corners, which due to square shape gives it an octagonal shape. Classic varieties are square with 1.00 length-width ratio. Often, one comes across rectangular varieties of this cut. Square appearance is for 1.05 ratios or less.


Color evaluation of Asscher Cut is subjective. Buyers may prefer warmer colors with G-H grade gemstones to colorless, cool D-F grade diamonds. Prices of Asscher Cut on higher grade color scale depend on demand and supply. Color is easier to discern in diamonds more than 1.50 carats owing to the presence of open, large facets.


This is another subjective feature of the Asscher Cut variety. Here again, individual clarity standard of the buyer becomes important. For example, some may be quite comfortable with stones that have inclusions provided these are not visible with the naked eye. On the other hand, some customers may require only a technically flawless stone. It is easier to spot inclusions in this shape of diamonds.
