An architectural choice for someone who likes clean lines

Emerald cut is a "step cut" — the facets are arranged in long parallel lines rather than the brilliant-cut star pattern. It produces flashes of light rather than continuous sparkle, and shows clarity more honestly than any other shape. The Collet pairs that crisp, art-deco look with brilliant-cut shoulders that add a touch of life next to the centre stone.

What to know about emerald cuts

Because emerald cuts have a large open table, we recommend VS1 clarity or above — any inclusion is visible. Colour can be slightly lower (G-H) without affecting the look. The Collet's centre stone is hand-selected to those specs before you see it.

Metals and customisation

Available in 9K, 18K white/yellow/rose gold, and platinum. The shoulder design can be specified as pavé set diamonds, channel set, or plain — let us know your preference and we'll render before commitment.

Made to order in the UK.

The setting is checked by a senior jeweller before despatch. Free fully-insured UK delivery, 30-day returns on in-stock pieces, and a lifetime warranty covering manufacturing defects and routine maintenance like claw re-tipping and re-polishing.
