Choosing an emerald cut lab-grown diamond engagement ring
Why choose an emerald cut
The emerald cut is calm, architectural and quietly glamorous. Its open table shows the clarity of the lab-grown diamond, which is why the quality of the stone matters more here than in almost any other shape.
Solitaire, halo or accents
An emerald cut solitaire is the purest expression of the shape. A halo of round lab-grown diamonds adds brightness around the step-cut centre, while baguette, princess or marquise accents continue its clean lines along the band.
Lab-grown diamond quality you can check
Every stone we set is a lab-grown diamond, D–F in colour and VS1 clarity or better. Rings with a centre stone of 1.00ct or above come with an individual IGI grading report as standard, at no extra cost.
Size and timing
Every ring is made to your size at no extra cost, including half sizes; use our ring size guide. Rings are made to order in around four weeks, including UK hallmarking where required, and UK delivery is free, tracked and signed for. Browse all our engagement rings.
Your questions
Are lab-grown diamonds genuine? Yes. They have the same chemical composition, hardness and sparkle as mined stones; only their origin differs.
