A square step-cut diamond known for its geometric symmetry and deep visual effect that creates a captivating layered light pattern.
Asscher cut diamonds are a square-shaped step cut defined by their deep structure, cropped corners, and strong geometric symmetry. Developed in the early 1900s, this style is closely associated with Art Deco design and architectural elegance.
The cut creates a striking layered visual effect, where light travels inward through concentric facets, producing a sense of depth and dimension rather than sharp sparkle. This gives it a bold and structured appearance.
Due to its open and transparent facet arrangement, clarity plays a major role in its overall beauty, as internal features are more easily visible. This makes it especially appealing to collectors who value precision and clean structure.
At John Ann Foley Diamond Institute, we analyze Asscher cut diamonds for their symmetry, optical depth, and historical importance. Our studies focus on how this cut continues to influence both vintage-inspired and modern luxury diamond design.
