Asscher Cut
A square step-cut diamond with deeply cropped corners producing an octagonal shape and a hypnotic windmill pattern.
Definition
The Asscher cut was created by the Asscher Diamond Company of Amsterdam in 1902 and enjoyed a revival in the 1920s Art Deco era. It is a square step-cut with heavily cropped corners (giving an almost octagonal outline) and a high crown, producing a distinctive concentric square pattern when viewed from above. The Royal Asscher Cut (2001) features 74 facets for added brilliance.
Why It Matters for Ring Design
Like the emerald cut, the Asscher's open table reveals inclusions easily. For maximum visual impact, choose VS1 or better clarity. The vintage aesthetic makes it a perfect match for Art Deco and antique settings.
