The emerald cut is a rectangular step cut — long, open facets that create a clear, dramatic 'hall of mirrors' rather than the crushed-ice sparkle of a brilliant. It is the most understatedly elegant shape, but its openness means clarity matters more than in any other cut. Here is how to choose one.
Key takeaways
- An emerald cut is a step cut — sleek flashes of light, not fiery sparkle.
- Its open facets show inclusions, so it rewards higher clarity.
- It also shows colour slightly more, so a high colour grade flatters it.
- It looks larger per carat thanks to its long face-up area.
- Ideal length-to-width ratio is roughly 1.30–1.50.
What is an emerald cut?
Where a round or oval is a brilliant cut — dozens of small facets bouncing light into sparkle — an emerald cut is a step cut, with long parallel facets arranged like stairs and trimmed corners. Instead of scintillation it produces broad, mirror-like flashes of light and dark: the famous 'hall of mirrors'. The effect is architectural, vintage-leaning and quietly luxurious.
Why clarity matters most for emeralds
Those long open facets act like windows into the stone — so any inclusion is far easier to see than in a sparkly brilliant cut that hides flaws in its flash. For an emerald cut, an eye-clean stone is non-negotiable, which is why higher clarity is the smart spend here. (See diamond clarity explained.) Montare's VVS1–VVS2 floor means an emerald cut is always clean, with room to spare.
Every centre diamond is Triple Excellent, D–E, VVS and at least three carats — the hard calls are made for you.
Design your ringColour and ratio
Emerald cuts also reveal body colour a little more than brilliants, so a high colour grade keeps them crisp and icy — Montare's D–E standard suits them perfectly. For shape, most people prefer a 1.30 to 1.50 length-to-width ratio: classic and elongating, neither too square (that veers toward asscher) nor too narrow.
The best settings for an emerald cut
Emerald cuts shine in clean, architectural settings: a solitaire on a slim band, a three-stone framed by tapered baguettes (see three-stone rings), or a hidden halo for a touch more sparkle. Explore options in our guide to settings and compare shapes in our visual guide.

See emerald rings →Frequently asked questions
Do emerald cut diamonds sparkle?
Not like a brilliant cut. They produce broad, mirror-like flashes — a 'hall of mirrors' — rather than fiery scintillation. The look is elegant and understated.
Why does clarity matter so much for emerald cuts?
The long open facets reveal inclusions that a sparkly cut would hide, so an eye-clean (ideally VVS) stone is important. Montare's VVS floor covers this.
What is the best ratio for an emerald cut?
Most people prefer a length-to-width ratio of about 1.30 to 1.50 for a balanced, elongated look.
Do emerald cuts look bigger?
Yes — their long, open face-up area makes them look larger per carat than many other shapes.
