Emerald Cut Lab Grown Diamonds

What defines an emerald cut lab grown diamond?

An emerald cut lab grown diamond is a rectangular step-cut stone with cropped corners, long parallel facets running the length of the table, and a characteristically open, hall-of-mirrors appearance. Unlike brilliant cuts, which scatter light into sparkle, the emerald cut holds light in broad flashes and deep reflections — a quality that rewards high clarity grades. Laboratory growth produces these stones under controlled thermal or chemical conditions that replicate the high-pressure environment of natural diamond formation. The resulting crystals are then cut and polished to the same specifications as mined emerald cuts, with the same characteristic length-to-width ratio typically sitting between 1.30 and 1.50.

Why choose an emerald cut for a lab grown diamond?

The emerald cut's large, open table makes it one of the most transparent shapes available — inclusions and colour tints are more visible here than in brilliant cuts, which makes the consistency of laboratory growth a genuine advantage. Lab grown diamonds tend to reach higher clarity grades at lower relative cost than comparable mined stones, and the emerald cut rewards that clarity directly. The shape also reads larger face-up than its carat weight suggests; a 1.0ct emerald cut typically measures around 6.5 mm × 4.5 mm, offering generous visual coverage. For those drawn to the architectural, rectilinear lines of Art Deco design, the emerald cut lab grown diamond is a natural fit.

What clarity and colour grade should an emerald cut lab grown diamond be?

For an emerald cut lab grown diamond, clarity of VS2 or above is generally advisable because the step facets act as a window into the stone — inclusions positioned near the centre of the table will be visible to the naked eye at SI1 and below. Colour grades of F or above are typically recommended for settings in platinum or white gold, where any warmth in the stone sits in full contrast to the metal. In yellow or rose gold settings, a G or H colour emerald cut lab grown diamond can read entirely colourless, since the warm metal absorbs and flatters slight body colour. Every emerald cut lab grown diamond sold here carries a GIA, HRD, or IGI certificate confirming cut proportions, clarity, and colour.

What does an emerald cut lab grown diamond cost in the UK?

Lab grown emerald cut diamonds are considerably more accessible per carat than their mined equivalents, primarily because laboratory production removes the extraction and supply-chain costs associated with mining. The price is shaped by carat weight, clarity, colour, and cut quality — proportions such as table percentage and depth percentage affect how well the step facets perform. For context, Bridebook's 2026 UK average engagement ring spend of £2,247 covers the full ring; a lab grown emerald cut diamond centre stone can leave more of that budget available for the setting. A 0.5ct VS1 F stone and a 2.0ct SI1 G stone occupy very different price points, so filtering by the certified grades matters more than carat weight alone.

How is an emerald cut lab grown diamond set into a ring?

When set into one of our rings, the emerald cut lab grown diamond goes through a full made-to-order process: CAD design, a silver or wax sample for review at the Hatton Garden workshop, casting, setting, and polishing before the finished ring is hallmarked at the London Assay Office. The cropped corners of an emerald cut make claw placement critical — four or six claws positioned precisely at each corner protect the geometry without obscuring the long step facets. A bezel or half-bezel setting suits those who prefer a lower profile, while a four-claw solitaire in platinum keeps the stone central and uninterrupted. Lead time runs 7–14 working days from order confirmation. Loose stones are sold separately on a 30-day return, no questions, no exclusions.
