Asscher Cut Diamond Buying Guide
Named after the Royal Asscher Diamond Company, Asscher cut was considered a revolutionary concept when it was created. While its popularity faded in the last century, Asscher cut diamonds are now considered a popular diamond shape. Demand for the shape particularly increased during early 2002, mostly because of cut modifications that gave the shape more brilliance. The open facets of Asscher cut diamonds create ostensibly incessant hallways lined with reflective mirrors, radiating elegant fire and brilliance.
The modern Asscher cut diamond shares similar features to a square emerald cut diamond, with both having a smaller table, a higher crown, and larger step facets. With proper positioning of the pavilion facets, an observer will notice that the Asscher cut diamond has lovely concentric squares. Besides, the square shape of the Asscher cut diamond, cropped corners give the cut a unique octagonal shape. Asscher cut will maintain its shape within a square silhouette if placed in a four-prong setting.
Key Insights on Asscher Cut
- Asscher diamonds are elegant and graceful. They are step-cut with open facets, unlike brilliant cut diamonds.
- Given the open facets, we recommend buying a high clarity grade Asscher cut diamond.
- In terms of color, D-F colors are considered colorless, while G is also a great color. Moreover, H and I colors are great budget options.
- A length-to-width ratio of 1 to 1.05 is ideal.
- While evaluating the cut, a depth of 60% to 68% and a table of 61% to 71% are recommended with a tolerance of 1-2% (up or down).
- Avoid fluorescence in the D-G color range; up to medium blue is great in H and I color.
- Buy a GIA or AGS-graded loose diamond.

The chart above serves as a general guideline when evaluating the cut of an Asscher cut diamond. For example, a 1.00 length-to-width ratio is considered classic for a square shape in the Asscher cut. While slightly rectangular shapes exist among Asscher cut diamonds, a ratio of 1.05 or less will appear square to the naked eye.
In short, analyzing the length-to-width ratio of each Asscher cut diamond is important before making a purchase.
Evaluating Asscher Cut Color
Color is a critical factor in Asscher cut diamonds. Like other diamond shapes, color in an Asscher cut diamond is subjective. Our experience indicates that many buyers prefer warmer colors over cooler ones due to affordability. In the color spectrum, the former (warmer colors) refer to G-I diamonds, whereas the latter (cooler colors) refer to D-F diamonds. On the positive side, the price premium for H and I color-grade Asscher cut diamonds is significantly lower compared to D-E color diamonds.
Fluorescence in a diamond is often a negative factor. However, it can be helpful to warmer color diamonds because blue is a complementary color yellow, making a diamond with a yellow hue appear whiter than its actual color grade.

Choosing Asscher Cut Clarity
Since Asscher cut diamonds have open facets, we recommend buying a slightly higher clarity Asscher cut diamond. Our customers have a unique standard for clarity and color; some want a flawless diamond, while others are comfortable with inclusions if they are not noticeable to the naked eye. GIA provides excellent help with their clarity grades. Use the GIA or AGS grading report to select an Asscher cut diamond based on our guidance outlined in this article.
SI1 would have an outstanding balance of price and appearance in an Asscher cut. However, we recommend VS2 or above in 1.5+ carat diamonds because Asscher cut diamonds have open facets.
