About the Asscher
Created in 1902 by Joseph Asscher in Amsterdam, the asscher cut is a square step-cut with deeply cropped corners that give it an almost octagonal appearance. It produces the same mesmerising hall-of-mirrors effect as the emerald cut, but in a square format with greater depth and a more pronounced "X" pattern when viewed from above. The Royal Asscher Cut, a patented 74-facet modification, adds extra brilliance while maintaining the step-cut character. This is the diamond of Art Deco — geometric, bold, and unmistakably sophisticated.

Size Guide
A 1-carat asscher measures approximately 5.5 x 5.5mm. Due to the deep cut, asschers can appear smaller face-up than other 1-carat shapes. Prioritise clarity (VS2+) and colour (G+) for the best visual result.
