The Asscher — the square step cut that turns clarity into architecture. Each stone certified by GIA, IGI or HRD, each setting made to order.












The Asscher is the step cut squared — a 1902 Amsterdam invention whose deep, cropped-corner geometry draws the eye down into the stone rather than across it. Where a brilliant cut scatters light, the Asscher builds a hall of mirrors: concentric square facets descending to the culet, the pattern collectors call the windmill. It rewards exactly two things, clarity and precision of cutting, and it forgives neither. Every asscher cut diamond in this collection is certified by GIA, IGI or HRD, and the certificate is shown before anything else is discussed.
The House's asscher cut rings run from under $10,000 into the millions at the highest carat weights, because the cut spans the whole vault — from wearable one-carat solitaires to statement stones above twenty carats. Colour and clarity move the figure more than the carat mark does. Every piece carries one transparent price — no first-offer theatre — and the 10 carat diamond ring price guide places the larger stones in their verified market range.
Same family, different temperament. The emerald cut is rectangular and reads long on the finger; the Asscher is square, sits deeper, and holds more fire in its step facets because the pattern is nearly octagonal. Choose the Asscher for symmetry and depth, the emerald for elongation. The asscher cut diamond buying guide sets out what to check on the certificate, and the emerald cut collection makes the comparison in person.
