Lab-Grown Emerald Cut Diamonds: The Complete Guide
An emerald cut lab-grown diamond is a step-cut stone with long parallel facets and bevelled corners, creating a clean, hall-of-mirrors play of light rather than overt sparkle. It suits buyers drawn to understated, clarity-forward elegance, and is independently certified by IGI or GIA at a VS1 minimum clarity. From $990 AUD for a 1ct VS1.
Overview
The Emerald diamond is revered for its understated elegance and unique step-cut design. This rectangular shape, with its cropped corners, emphasises clarity and transparency over scintillation. Unlike brilliant cuts, the emerald cut reveals the stone’s inner beauty through its large, open table and long, graceful facets. The cut is less about flash and more about a refined, sophisticated allure, making it a perfect choice for those who value subtlety and timeless style in their jewellery.
Origin and development
The emerald cut has its roots in antique jewellery, where its simple yet elegant design was highly valued for showcasing a diamond’s natural clarity. Over the years, this cut has evolved to meet modern tastes while preserving its traditional charm. It remains a testament to the enduring appeal of minimalist design, reflecting a heritage that honours both the stone’s intrinsic beauty and the artistry of early diamond cutters. Today, the emerald cut is celebrated for its ability to combine classic sophistication with a contemporary edge.
How the emerald cut is shaped
The emerald cut is characterised by a rectangular silhouette with clean, parallel facets that taper to cropped corners. This step-cut faceting emphasises the stone’s clarity and structure, creating a sophisticated, linear pattern that is both modern and vintage. The design is carefully calibrated to minimise optical distortion, ensuring that light passes through the stone in a controlled, elegant manner. Its refined geometry and spacious table contribute to a graceful, elongated appearance that stands out in both classic and contemporary jewellery designs.
Why choose a emerald cut
Emerald diamonds offer a distinct “hall of mirrors” effect, where the long, step-cut facets create an elegant play of light and shadow. This design brings out the stone’s clarity and natural transparency, allowing its internal characteristics to shine through. The emerald cut’s subdued brilliance is a celebration of purity and refinement rather than overt sparkle. It appeals to connoisseurs who appreciate a classic, vintage-inspired aesthetic that exudes both grace and understated luxury, providing a unique alternative to more common brilliant cuts.
What to look for when buying
Because step cuts show clarity openly, prioritise an eye-clean stone (VS1 or better) and even, parallel facets. Symmetry matters more than raw sparkle. Every CRTD stone is independently certified by IGI or GIA at a VS1 minimum clarity.
Price
Lab-grown emerald cut diamonds at CRTD start at $990 AUD for a one carat stone, with AU-inclusive pricing, the number you see is the number you pay. Larger carats and higher clarity grades are priced transparently across the range.
Choosing well
The emerald cut's open table and step faceting are unforgiving: with fewer facets to disguise flaws, inclusions and colour read more visibly than in a brilliant cut, so clarity matters more here than carat. Prioritise an eye-clean stone at VS1 or above, and look for a length-to-width ratio between 1.30 and 1.50 for the classic, well-balanced rectangle.

Common questions
What is the ideal length-to-width ratio for an emerald cut?
The classic emerald cut sits between 1.30 and 1.50 length-to-width, giving the elongated rectangle most buyers picture. Ratios near 1.30 look squarer and fuller; closer to 1.50 reads longer and more slender. It comes down to preference, so view stones across the range before deciding which proportion suits you.
Do emerald cut diamonds hide inclusions well?
No, they tend to reveal them. The step-cut faceting and large open table create clear flashes rather than dense sparkle, so inclusions and tinting show more readily than in brilliant cuts. This is why clarity matters most here. We recommend an eye-clean stone at VS1 or above, which every CRTD emerald cut meets as our minimum.
Is an emerald cut durable enough for everyday wear?
Yes. Its corners are bevelled rather than sharply pointed, which reduces the risk of chipping and makes the emerald cut a sound choice for daily wear. As with any diamond, a secure setting helps protect the stone. The main consideration is clarity rather than toughness, since the open facets show inclusions clearly.
