Emerald cut lab grown diamonds work differently from a brilliant cut, using long, open step facets and a broad table that let you see straight into the stone rather than scattered sparkle. With an emerald cut, clarity is more visible than in almost any other shape. It’s the first thing our Hatton Garden team checks on every loose stone we consider, along with how evenly the step facets are spaced and how crisp the corners are cut. All stones are independently certified by GIA or IGI, so carat, colour and clarity are always verified.
Whether you prefer a longer, more elongated shape or one closer to square, we’ve curated a wide range of carat weights and colour grades to suit every budget and style. Once you’ve chosen your stone, we can set it into a ring designed entirely around it.

The emerald cut traces its origins back to the 1500s, originally used by gem cutters to enhance the beauty of emeralds. Over time, its refined step-cut style was adopted for diamonds, creating a sophisticated look admired for centuries. Today, lab grown emerald cut diamonds bring the same iconic appeal with a modern, sustainable twist. Their clean lines and elegant symmetry make them a favorite for those seeking a bold yet classic statement.
Emerald cut lab grown diamonds showcase their beauty best in near-colourless to colourless grades, typically ranging from D to H on the GIA scale. Because the step-cut facets emphasise clarity and transparency, even slight colour can be more noticeable compared to brilliant cuts. Choosing higher colour grades enhances the crisp, bright appearance that buyers love in emerald cuts. For those seeking a warmer tone, lower grades can also pair beautifully with yellow or rose gold settings.
The step-cut faceting of emerald diamonds creates a “hall-of-mirrors” effect that highlights transparency. This makes inclusions or blemishes easier to spot, so a higher clarity grade is often recommended.
Most people prefer a ratio between 1.3 and 1.6. A longer ratio elongates the finger, while a shorter, closer-to-square stone looks bolder. Our team can help you compare ratios in person before you decide.
Emerald cuts pair beautifully with solitaires, three stone rings, halo settings, and east-west designs. These styles highlight the clean lines and bold presence of the cut.
It’s the reflective, mirror-like pattern created by the step-cut facets as light bounces between them. A well-cut stone shows this clearly, which is one of the first things our team looks for.
The corners are the most vulnerable part of the stone, especially if the girdle is cut too thin. Our team checks girdle thickness on every step cut diamond to help avoid this.
Excellent or Very Good is generally recommended, since precision cutting is what creates the sharp hall-of-mirrors effect this shape is known for.
Because the open facets show colour more clearly, many buyers choose G or above for a brighter look. Our team can show you a few grades side by side to help you compare.
It can, its broad table and elongated shape often make it appear larger on the hand than a round diamond of the same carat weight.
Yes, chemically, physically and optically. Every stone we offer is independently certified by GIA or IGI, so you know exactly what you’re getting.
Yes, though because of its rectangular shape, resizing is best done by a jeweller experienced with step cuts, to keep the proportions and prong alignment correct. Our Hatton Garden team can handle this for you.
A soft brush with warm water and mild soap works well, the open facets can show dust or oil more easily than other cuts, so regular cleaning helps keep the sparkle visible.
