What is an Asscher cut diamond?

Asscher-cut-diamond-blue An Asscher cut diamond is a type of diamond shape, named after the Ascher family, who invented it. It’s a stepped cut that resembles the emerald square cut. There are no typical proportions for this diamond because they are very rare. The range of Asscher cuts that one can get is also much smaller than the other common cuts that are available.

The modern Asscher cut gives out more brilliance than the emerald cut. If you are looking for a well-cut Asscher diamond, it will look as if it has concentric squares, which is mainly because the pavilion facets underneath it are properly positioned. When the Asscher cut is mounted on a four prong setting, it maintains its shape within a square silhouette. Compared to the emerald cut, the Asscher has larger step facets with a higher crown and a table that is smaller. This diamond has cropped corners like the emerald cut and it gives it a kind of octagonal shape because it is square.

The classic Asscher cut diamond has a length to width ratio of 1.00 and it is a square, though they can be found having a slightly rectangular shape at times. If the Asscher cut has a ratio of 1.05 or anything less, it will have a square appearance to the bare eyes.

HISTORY OF THE ASSCHER CUT DIAMONDCushion-cut-diamonds-compared-with-Pear-radiant-emerald-and-Ascscher-cut

The Asscher cut diamond was first produced by the Asscher Brothers of Holland in 1902; they were very famous then because they cut the largest rough stone in the world ‘the Cullinan’, weighing 3,106 karats. The popularity of Asscher diamonds increased in 1920 and they can recently be found in antique shops that sell jewelry. The Asscher diamond is just making a comeback in 2002, a hundred years after the shape emerged. This is as a result of cut modifications that make the diamond appear as if it has more brilliance than the traditional Asscher cut.


The G-H Asscher cut diamonds come in a slightly warm color while the D-F diamond is cool and colorless but buyers most times prefer the slightly warm colors of the G-H diamond over the D-F diamond. As a matter of fact, the premium in price of the Asscher cut diamonds at the color scale higher end is determined by the law of supply and demand. Customers will not mind parting with a huge sum of money to get their preferred choice. Without color grading for diamonds, the premium value for higher grades would be lesser. In a large Asscher cut diamond of over 1.50 karats, it is easier to see the body color of the diamond because of the large open facets.


Using the GIA diamond clarity scale is an excellent way of evaluating the clarity of an Asscher cut diamond. Apart from this way of evaluating clarity, each customer also has their own standard that they use in evaluating the clarity of the stone. While some will take nothing short of a technically flawless appearance, others are comfortable with a diamond that has an inclusion once it is not easily visible to the eye. While the SI1- clarity will give you a good balance between its price and appearance, the Asscher cut of VS2 clarity has the best value.
