Asscher Cut Diamond Engagement Rings: Art Deco Elegance
The Asscher cut is one of fine jewelry's most distinctive shapes, a square step cut with cropped corners and a deep, hypnotic "hall of mirrors" effect. First cut in 1902 by the Asscher Brothers of Amsterdam, it became a defining look of the Art Deco era and remains the choice for anyone who loves geometric, vintage-inspired elegance. At Stienhardt, our Asscher cut engagement rings are handcrafted in New York's Diamond District and set with IGI- or GIA-certified lab-grown diamonds.
What makes the Asscher cut special
- Geometric, Art Deco character, a square outline with cropped corners and crisp step facets.
- The famous "hall of mirrors", concentric facets draw the eye into the heart of the stone.
- Understated, timeless elegance rather than flashy brilliance, a quietly confident look.
How to choose your Asscher
Because the Asscher's open step facets reveal more, prioritise clarity (VS1, VS2 is eye-clean at most sizes) and an even colour (F to G for white metals, H for yellow or rose gold). A true Asscher is square, with a length-to-width ratio around 1.00 to 1.05. Every Stienhardt centre stone ships with a full IGI or GIA grading report.
Settings that suit an Asscher
Solitaires let the geometry speak for itself; halos and three-stone designs amplify its Art Deco character. Vintage-inspired and milgrain settings are especially at home with this cut. Prefer to start with the stone? Browse our loose Asscher cut lab grown diamonds.
