The diamond

An overview

The square emerald cut applies the elegant step-cut faceting of a traditional emerald to a perfectly square outline. Where the standard emerald is elongated, the square emerald offers equal proportions on all sides, creating a balanced, centred presence on the finger. Its open facets produce the same mesmerising hall-of-mirrors optical effect, but within a more compact, symmetrical frame.

Heritage

Origin & development

The square emerald cut emerged as a natural extension of the rectangular emerald, developed by cutters who sought to offer the step-cut aesthetic in a more symmetrical format. While the Asscher cut also offers a square step-cut profile, the square emerald differs in its corner treatment and facet arrangement, featuring broader, more open facets and less pronounced corner cuts. This gives it a distinct visual identity that sits between the Asscher's Art Deco drama and the emerald's elongated elegance.

The cut

How it's shaped

The square emerald is defined by its 1:1 length-to-width ratio and broad, open step-cut facets. The corners are trimmed at a shallow angle - less aggressively than an Asscher - preserving the square outline while reducing vulnerability to chipping. The large table and open pavilion facets create maximum transparency, making this shape a showcase for exceptional clarity. Every inclusion and nuance is visible, rewarding those who invest in high-quality rough material.

Why this cut

Highlights

The square emerald is the choice for buyers who love the emerald cut's sophisticated shimmer but prefer a balanced, centred profile. Its equal proportions create a sense of groundedness and stability on the finger, while the step-cut facets maintain the refined, understated light performance that step-cut enthusiasts seek. It pairs beautifully with both modern and vintage settings, and its rarity relative to standard emeralds adds an element of exclusivity.
