Asscher-cut diamond – Retro luxury with graphic precision
Asscher-cut diamonds are distinguished by their Art Deco feel, symmetrical shape and distinctive “hall of mirrors” effect. The shape is square with beveled corners and deep, stepped facets – a combination that creates an elegant and architectural aesthetic.
History and origins
Developed in 1902 by Joseph Asscher in Amsterdam, the Asscher cut was one of the first cut shapes to be patented. It gained its real popularity during the Art Deco era of the 1920s and is often used in vintage-inspired jewelry.
The modern “Royal Asscher-cut” has additional facets for increased brilliance, but the classic cut is still loved for its clarity, balance and retro character.
Benefits of Asscher cut diamond
- Graphic symmetry: Sharp, structured form with sophisticated depth.
- Vintage feel: Perfect for those looking for a unique, classic style.
- Focused clarity: The cut highlights the purity of the stone – especially in higher clarity grades.
