The connoisseur's diamond. Where brilliants scatter light into sparkle, the emerald cut arranges it into long, deliberate flashes, a hall of mirrors instead of a fireworks show. It hides nothing, which is exactly why the people who choose it, choose it.
The emerald cut is the definitive step cut: a rectangle with cropped corners and long, parallel facets that descend the pavilion like terraces. Developed for the gemstone that gave it its name, it trades the brilliant's scattered sparkle for something rarer, broad planes of light that sweep across the stone as it moves, the effect the trade calls the hall of mirrors.
That open architecture is a window, and windows conceal nothing. Inclusions that a brilliant's faceting would shred into invisibility sit in plain view under an emerald cut's glassy table, and body color pools in its long corridors. The shape therefore demands more of its stone: higher clarity, careful color, and rough of genuine quality. This is why the emerald cut has always read as a connoisseur's choice; it is a shape that can afford honesty.
Its reward is unmistakable. On the hand, an emerald cut is architectural, elongating, and quietly assured. It does not compete for attention with glitter; it holds attention with clarity, the way still water holds a reflection.
| Facets | Typically 57 to 58, step cut in parallel rows |
| Cut grading | No formal lab cut grade, evaluate by eye |
| Face-up size | Large spread for its weight, shallow profile |
| Length to width | 1.30 to 1.50 is the classic range |
| Relative price | Meaningfully below round per carat |
| Watch for | Clarity and color, the step cut hides neither |
The emerald cut is one of the most efficient shapes in diamonds: its shallow, rectangular geometry spreads weight across the finger, so it faces up generously for its carat. What the table shows in size, it also shows in truth, which is why the sizing decision and the clarity decision travel together on this shape.
| Carat Weight | Typical Measurements | How It Wears |
|---|---|---|
| 0.75 ct | 6.5 x 4.5 mm | A refined, architectural line on slender hands |
| 1.00 ct | 7.0 x 5.0 mm | The classic proportion, unmistakably emerald |
| 1.50 ct | 8.0 x 5.8 mm | Long, confident planes of light |
| 2.00 ct | 8.8 x 6.4 mm | Serious presence with a low, elegant profile |
| 3.00 ct | 10.1 x 7.3 mm | A gallery piece across the finger |
Measurements are typical for well proportioned stones. Individual diamonds vary with their cutting.
The step cut shows you everything the certificate describes, so on an emerald cut the paperwork matters more, not less. Here is where your attention belongs.
The open table forgives nothing. We recommend VS1 as the working floor for emerald cuts, VS2 only on stones our gemologists have verified eye clean face up. The SI savings that work beautifully on brilliants are the most common regret on step cuts.
Long corridors of glass pool body color more than any brilliant. In platinum or white gold, hold G or better; in yellow gold, H still reads clean. Whatever grade your setting suggests for a round, an emerald cut deserves one step up.
On video, tilt the stone. A well cut emerald flashes long planes of dark and light in rhythm; a poorly cut one goes see-through in the center, called windowing, or dead across a whole step. Neither appears anywhere on the certificate.

The emerald cut brings its own architecture, so the strongest settings frame it rather than decorate it. These three directions cover most of what our clients choose, each made to order around your exact stone.
Four sturdy corner-adjacent prongs and a clean band. The emerald cut's geometry needs no help, and the unadorned mount is the shape's most enduring look.
Flanked by tapered baguettes or trapezoids that continue the step cut language down the finger. The definitive emerald cut composition, formal and complete.
The rectangle turned sideways and wrapped in metal. Modern, low, armor-quiet, and a favorite of buyers who wanted an emerald cut precisely because it is not what everyone else chose.
The emerald cut is a window, not a mirror ball. Buy the stone as if every grade on the certificate will be visible, because it will be.
We will not sell you sparkle on this shape, because that is not what it does. The emerald cut trades fire for architecture, and it makes the trade honestly: lower price per carat than the round, generous spread for its weight, and a presence nothing else in diamonds matches. In exchange it demands the clarity and color budget the brilliants let you skip, and it must be seen in motion before purchase, because windowing and dead steps live outside the certificate. If your budget concentrates on size over grades, we will honestly steer you toward a radiant or an oval and tell you why. If the hall of mirrors is what you want, nothing else will do, and we will find you a stone that earns it.
