Asscher Cut
A square step-cut diamond with deeply cropped corners producing an octagonal shape and a hypnotic windmill pattern.
Definition
The Asscher cut is a square step-cut diamond with deeply trimmed corners that give it a distinctive octagonal appearance. Created by Joseph Asscher in 1902, it features a high crown and deep pavilion that produce a mesmerizing windmill or concentric-square pattern when viewed from above. The modern Royal Asscher cut has additional facets for greater brilliance.
Why It Matters for Ring Design
Asscher cuts appeal to vintage-loving clients and those drawn to art-deco design. Like emerald cuts, they emphasize clarity, so higher-clarity stones are recommended. Their deep pavilion can make them appear smaller face-up than other shapes of equal carat weight.
