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. GIA or IGI certification is available on centre stones, and we source certified stones to your brief, sharing the full grading and details of each stone before we recommend one.
Who it suits
The emerald cut suits a particular eye: clean Art Deco lines, restraint over flash, an appreciation for geometry. It 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 keeps the attention on the geometry and shows the cut at its simplest. 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 specialist workshops, and hallmark each ring at the London Assay Office.
Commissioning with us
We work by appointment from our studio at Unit 1.02, The Goldsmiths' Centre, 42 Britton Street, London EC1M 5AD. A commission begins with a consultation, where we discuss the stones we will source and settle on the cut, ratio and grade that suit you, then move to CAD design and the bench. Bespoke engagement rings start from £2,000, with most commissions between £3,000 and £12,000. Larger commissions are quoted individually, and some go well beyond £20,000. You receive a full written quote before any work begins. Turnaround is three to four weeks from CAD approval, with consultation to CAD usually seven to ten days. An urgent commission can sometimes be accommodated for a significant additional fee, quoted before we begin. Delivery within the UK is free, fully insured and tracked; international delivery is arranged and insured on request.
