Lab-Grown Asscher Cut Diamonds: The Complete Guide
An Asscher cut lab-grown diamond is a square step-cut stone with cropped corners and deep, concentric facets that draw the eye inward. Its Art Deco geometry suits buyers who favour clean symmetry and architectural depth over sparkle. Every CRTD Asscher is independently certified by IGI or GIA at a VS1 minimum clarity, from $1,090 AUD for a 1ct VS1.
Overview
Developed in the early 20th century by the Asscher Diamond Company in Amsterdam, the Asscher cut emerged during the Art Deco era, when bold geometric designs were in vogue. Its creation was influenced by the desire to combine modern cutting techniques with a vintage aesthetic. Over the decades, the Asscher has become synonymous with luxury and refinement, retaining its status as a timeless choice for those seeking a diamond with a rich historical and artistic pedigree.
Origin and development
The Asscher diamond is a square variation of the emerald cut, known for its distinctive deep pavilion and high crown. This cut creates a dramatic “hall of mirrors” effect with its step facets, resulting in a unique interplay of light and geometry. The Asscher is highly regarded for its refined, art deco style, offering an elegant blend of vintage charm and modern precision. Its square shape and intricate faceting elevate the diamond’s natural beauty, making it a sophisticated choice for discerning buyers.
How the asscher cut is shaped
Asscher-cut diamonds are prized for their exceptional symmetry and bold optical appearance. The cut’s unique faceting produces a cascade of reflections and refractions that create a mesmerizing depth and intensity. Its ability to display intricate internal details is enhanced by the high crown and deep pavilion, offering an immersive viewing experience. This cut not only maximises brilliance but also highlights the stone’s clarity and character, making it a statement piece that exudes timeless sophistication and artistic flair.
Why choose a asscher cut
The Asscher cut features a distinctive square shape with cropped corners, characterised by large, step-cut facets that form a geometric pattern. Its design focuses on creating an illusion of depth, with a high crown that amplifies the stone’s internal light play and a deep pavilion that adds dramatic contrast. The interplay between the open facets and solid structure gives the diamond a unique “hall of mirrors” effect, producing a refined, vintage-inspired look that is both modern and classically elegant. The overall shape exudes precision and symmetry, appealing to those with an eye for detail.
What to look for when buying
Because step cuts show clarity openly, prioritise an eye-clean stone (VS1 or better) and even, parallel facets. Symmetry matters more than raw sparkle. Every CRTD stone is independently certified by IGI or GIA at a VS1 minimum clarity.
Price
Lab-grown asscher cut diamonds at CRTD start at $1090 AUD for a one carat stone, with AU-inclusive pricing, the number you see is the number you pay. Larger carats and higher clarity grades are priced transparently across the range.
Choosing well
The Asscher rewards depth and symmetry rather than flash: its concentric step facets create a hall-of-mirrors effect that only reads cleanly when the cut is precise and the table is well centred. Because those open facets act like windows, clarity and symmetry carry more weight here than in a brilliant cut, so screen for an eye-clean stone first. Hold the diamond face-up and check that the corners and step lines mirror each other evenly.

Common questions
What is the ideal length-to-width ratio for an Asscher cut diamond?
An Asscher reads as square, so aim for a length-to-width ratio of 1.00 to 1.05. At 1.00 the outline is perfectly even; up to 1.05 stays visually square to the eye. Ratios beyond this start to look rectangular and lose the balanced, geometric symmetry that defines the cut.
Does an Asscher cut hide inclusions well?
No. The Asscher's open step facets behave like clear windows, so inclusions and uneven symmetry show more readily than in a brilliant cut. Prioritise an eye-clean stone with strong symmetry. Every CRTD Asscher is certified at a VS1 minimum clarity by IGI or GIA, which keeps inclusions discreet under normal viewing.
Is an Asscher cut durable enough for everyday wear?
Yes. The Asscher's cropped corners remove the vulnerable sharp points found on some shapes, making it durable and well suited to daily wear. As with any diamond, a secure setting that shelters the corners is sensible. Pricing starts from $1,090 AUD for a 1ct VS1, independently certified by IGI or GIA.
