An emerald cut diamond trades brilliance for clarity of a different kind, long, open facets that act like a hall of mirrors rather than the scattered sparkle of a round brilliant. It is a shape built for buyers who want elegance through structure rather than maximum fire.
Emerald Diamond Size Chart: MM to Carat

Figures assume a standard length to width ratio near 1.4. An IGI certificate confirms a specific stone's actual measurements.
Why Clarity Matters More on an Emerald Cut
The emerald's broad, open facets act like a window into the stone, making inclusions considerably easier to spot than on a round brilliant, where the facet pattern hides small imperfections. Buyers choosing an emerald cut should prioritise a higher clarity grade than they might on a round or cushion stone of the same size.
The Hall of Mirrors Effect
Rather than scattering light into many small flashes, an emerald cut produces broad, elegant planes of brightness, sometimes called the hall of mirrors effect. It is a quieter kind of brilliance, favouring clean lines over sparkle.
Best Settings for an Emerald Diamond
A four prong or bezel setting that protects the stone's exposed corners, historically the most vulnerable point on a step cut shape, is the standard, secure choice. A trapezoid or baguette side stone setting echoes the stone's own architectural lines.
