Asscher Cut & Square Emerald Engagement Rings

The square emerald cut also known as the Asscher cut is one of the most architecturally stunning diamond shapes ever created. With its deep step-cut facets, perfectly square outline, and dramatic cropped corners, the Asscher creates a geometric pattern of concentric squares inside the stone when viewed from above, often called the "hall of mirrors" effect. It is the choice of someone who appreciates geometry, depth, and sophistication over conventional sparkle.
Originally designed by Joseph Asscher in 1902, the Asscher cut experienced a major revival in the Art Deco era and has never lost its reputation as the most distinctive and architecturally pure of all diamond cuts. Today it sits alongside the emerald cut as the defining shape for buyers who want a ring that looks unlike anything else.
