The History and Origin of the Asscher Cut

Royal Heritage
Created in 1902 by Joseph Asscher of the renowned Asscher Diamond Company in Amsterdam, this cut gained fame when Joseph was chosen to cut the legendary 3,106-carat Cullinan Diamond for the British Crown Jewels.
The Asscher cut became synonymous with luxury and sophistication during the Art Deco era of the 1920s, when its geometric lines perfectly captured the period's aesthetic zeitgeist.

Expert Tips & Advice
Clarity is King
Because of its large, open table and long step-cut facets, the Asscher cut acts almost like a magnifying glass into the diamond's interior. Unlike brilliant cuts that scatter light into countless tiny reflections — effectively hiding minor imperfections — the Asscher's broad, flat facets leave inclusions and blemishes far more visible to the naked eye. For this reason, we strongly recommend selecting a clarity grade of VS1 or higher to ensure a clean, flawless appearance that lets the hall-of-mirrors effect shine without distraction. When reviewing a grading report, pay close attention to the inclusion plot — inclusions positioned near the centre or directly beneath the table will be the most noticeable, while those tucked near the cropped corners tend to be far less visible once the stone is set.
Perfect Proportions
The Asscher cut's beauty relies heavily on precise proportions, and even small deviations can significantly affect how the stone looks on the finger. Look for a length-to-width ratio between 1.00 and 1.05 for a perfectly square appearance — the hallmark of a classic Asscher. The ideal table percentage falls between 61% and 69%, while depth should range from 61% to 68% for optimal light performance. Stones that fall outside these ranges may appear either too shallow — causing light to leak through the bottom — or too deep, creating dark, lifeless areas within the step-cut facets. At Labelle, we carefully evaluate every Asscher diamond's proportions to ensure the concentric rectangular facets produce that mesmerising depth and symmetry the cut is known for.
Colour Considerations
Step-cut diamonds like the Asscher tend to reveal body colour more readily than brilliant-cut shapes, because the broad, flat facets don't break up light into as many colourful flashes. This means any warmth or tint in the stone becomes more apparent, particularly in larger carat sizes where the greater surface area amplifies even subtle colour differences. For settings in white gold or platinum, we recommend selecting colour grades of G or higher to maintain a bright, icy white appearance that complements the cool metal tone. If you're opting for yellow or rose gold, you can comfortably choose H or I grades, as the warm metal naturally blends with any slight warmth in the diamond — offering meaningful savings without any visible compromise in beauty.
Choosing the Right Setting
The setting you pair with an Asscher cut diamond plays a crucial role in how the stone's unique geometric character is presented. Because the Asscher is inherently bold and architectural, it tends to look best in settings that echo its clean lines and Art Deco heritage. A classic solitaire with double prongs at each corner offers both security and a refined, vintage-inspired aesthetic that lets the step-cut facets take centre stage. For those who want additional presence, a trilogy setting with two complementary side stones adds visual weight while maintaining the cut's sophisticated geometry. Art Deco-inspired settings with milgrain detailing or geometric metalwork are a natural match, honouring the era in which the Asscher cut rose to prominence. Avoid overly ornate or heavily curved designs that can clash with the cut's angular, structured beauty — simplicity and precision are the Asscher's best friends.
