The emerald cut is a step cut: a rectangular stone with a long, open table and parallel facets that run like steps to the edge. Instead of the busy sparkle of a brilliant, it gives broad flashes of light and shadow, a quiet play that rewards a steady look. It is among the most architectural cuts we work with, and one that asks for the right stone rather than the largest.
What an emerald cut looks like
Where a round brilliant is cut for scintillation, the emerald cut is cut for clarity of line. Its facets are arranged in concentric rectangular steps, and the large open table acts as a window into the stone. Light moves across it in long, measured planes, producing those characteristic flashes rather than a fine spray of sparkle. Most emerald cuts sit at a length-to-width ratio of around 1.30 to 1.50: closer to 1.30 reads squarer and fuller, closer to 1.50 longer and more slender. The right ratio is a matter of proportion on the hand, which we consider together with the certified stones we source to your brief.
Why clarity and colour matter more
That open table is the emerald cut's signature and its discipline. With so little faceting to break up the light, the eye sees straight into the diamond, so inclusions and body colour show more readily than they would in a brilliant of the same grade. This is where consultation earns its place. We guide you to a clarity grade that stays clean to the eye and a colour grade that holds its white, so the stone looks as composed on the finger as it does under the loupe. Every centre stone carries GIA or IGI certification, and we source certified stones to your brief, sharing full grading and detail so you can choose with confidence before we recommend it.
Who it suits
The emerald cut suits a particular eye: clean Art Deco lines, restraint over flash, an appreciation for geometry. It wears with quiet confidence and reads as understated rather than showy. It carries a practical advantage too. Because the stone is shallow and elongated, it presents a larger footprint per carat than many other cuts, so the diamond looks generous on the hand for its weight.
Settings and metals
An emerald cut is at its best in settings that respect its lines. A solitaire on a fine band lets the geometry speak for itself and is the purest expression of the cut. A three-stone design with tapered baguettes flanking the centre stone carries the step-cut language across the whole ring and adds width without clutter. Platinum and white gold give the crisp, cool frame the cut calls for, keeping the emphasis on clarity and line; yellow and rose gold are possible if you prefer warmth. We design every setting in-house in CAD and hand-finish it at our own bench, with casting and setting carried out by trusted specialist workshops, and hallmark each piece at the London Assay Office.

Frequently asked questions
Do emerald cuts sparkle?
Not in the way a round brilliant does. An emerald cut produces broad flashes of light and dark across its open table rather than a fine, busy sparkle. If you want maximum brilliance, a brilliant cut is the better fit; if you prefer a calmer, more architectural play of light, the emerald cut is made for it.
What clarity is safe in an emerald cut?
Because the table is open, clarity matters more here than in a brilliant, but no single number fits every stone. We source certified stones to your brief and share full grading and detail to guide you to a grade that stays clean to the eye, so you are not paying for a grade you cannot see. We show you the difference at consultation.
Natural or lab-grown?
We offer both, and the emerald cut looks beautiful in either. Lab-grown diamonds let you put more size or a higher grade within a given budget, which can help given how much this cut shows. Natural diamonds carry their own value and history. Whichever you choose comes with GIA or IGI certification.
