Square Emerald Cut Lab-Grown Diamonds: The Ultimate Guide
Square Emerald Cut Lab-Grown Diamonds
The square emerald cut diamond represents the perfect fusion of vintage elegance and modern sophistication. With its clean lines, distinctive step-cut facets, and mesmerizing "hall of mirrors" effect, this architectural marvel has captivated diamond enthusiasts for generations. Once known primarily as the Asscher cut, the square emerald cut has experienced a remarkable renaissance in contemporary jewelry design, particularly in the sustainable lab-grown diamond market. Labrilliante's collection of square emerald cut lab-grown diamonds offers all the visual splendor of this iconic design with the ethical and environmental benefits of laboratory creation, making them a compelling choice for the conscientious modern consumer.

What is a Square Emerald Cut Lab-Grown Diamond?
A square emerald cut diamond is a sophisticated step-cut gemstone characterized by its square shape, cropped corners, and parallel facet arrangement. Unlike brilliant cuts that maximize sparkle, the square emerald cut (also known as the Asscher cut) features a series of parallel facets that create a distinctive "hall of mirrors" effect. At Labrilliante, our square emerald cut lab-grown diamonds feature 58 facets arranged in a step-like pattern, with a length-to-width ratio of 1.00-1.05, ensuring perfect symmetry and proportions.
What distinguishes our square emerald cut from the traditional emerald cut is its perfectly square shape rather than rectangular proportions. The beauty of this cut lies in its extraordinary clarity and transparency, allowing the diamond's natural brilliance to shine through in a more understated yet sophisticated manner than brilliant cuts. Labrilliante's lab-grown square emerald cut diamonds offer exceptional optical performance while maintaining the ethical standards and environmental benefits that conscious consumers demand.
History and Origins
The square emerald cut diamond traces its lineage back to the early 20th century, with roots in the Art Deco period when geometric precision and architectural influence dominated jewelry design. The cut was pioneered by the Asscher family of Amsterdam in 1902, who refined the traditional table cut to create a revolutionary new shape with enhanced brilliance and clarity. Joseph Asscher, a master diamond cutter, created what would become the signature cut of his family's diamond company.
During the Art Deco era (1920s-1930s), the square emerald cut gained tremendous popularity for its clean lines and geometric symmetry. After a period of reduced popularity following World War II, the cut experienced a remarkable revival in the early 2000s as vintage and antique styles returned to favor. Today, Labrilliante honors this rich heritage by creating exquisite lab-grown square emerald cut diamonds that maintain the historic design's integrity while embracing modern sustainable technology—perfect for those who appreciate both tradition and innovation.

Square Emerald vs Emerald vs Asscher Cut: Key Differences
Understanding the distinctions between square emerald (Asscher), traditional emerald, and other popular cuts is essential when selecting the perfect lab-grown diamond. At Labrilliante, we offer comprehensive guidance to help you navigate these subtle yet significant differences.
The square emerald cut (often referred to as the Asscher cut) differs from the traditional emerald cut primarily in its proportions. While both feature step-cut faceting patterns that create dramatic flashes of light, the square emerald maintains a nearly perfect 1:1 length-to-width ratio, compared to the rectangular shape of the classic emerald cut. For those seeking absolute geometric precision, Labrilliante's square emerald cut lab-grown diamonds deliver unmatched symmetry.

Unique Features and Aesthetic Appeal
The square emerald cut lab-grown diamond possesses a distinctive allure that sets it apart from other diamond shapes. At Labrilliante, we particularly value this cut for its sophisticated geometric precision and understated elegance.
The most captivating feature of our square emerald cut diamonds is the mesmerizing "hall of mirrors" effect. Unlike the scattered light reflections of brilliant cuts, the step-cut faceting creates a series of parallel reflections that appear to extend infinitely within the stone—like looking down a corridor of endless mirrors. This unique optical property creates dramatic flashes of light rather than the continuous sparkle of brilliant cuts.
Square emerald cut diamonds from Labrilliante emphasize clarity and transparency. The large, open table (top facet) acts as a window into the diamond's interior, showcasing its exceptional purity. This transparency also enhances the diamond's color, making it particularly striking in colorless grades or fancy colored lab-grown diamonds. The clean, architectural lines of this cut appeal to those with sophisticated taste who appreciate minimalist design and Art Deco influences.

Quality Criteria
Clarity: Due to the step-cut faceting and large open table, square emerald cuts act as magnifying glasses for internal inclusions. For this reason, Labrilliante recommends selecting a clarity grade of VS2 or higher for optimal visual appeal. Our lab-grown diamonds typically achieve exceptional clarity due to their controlled growth environment.
Color: The transparent nature of square emerald cuts also emphasizes color. For a colorless appearance, we suggest G color grade or higher. However, some clients prefer the subtle warmth of H-J colors, which can complement rose or yellow gold settings beautifully.
Cut Quality: Pay particular attention to symmetry and polish. At Labrilliante, we ensure every square emerald cut diamond exhibits perfect symmetry, with parallel facets and precise angles that create the signature "hall of mirrors" effect.

FAQ Square Emerald Cut Lab Grown Diamonds
No, square emerald cut lab-grown diamonds are typically priced similarly to other cuts of the same quality. At Labrilliante, our pricing is based primarily on the diamond's carat weight, color, and clarity rather than the cut. However, because square emerald cuts require expert craftsmanship to execute properly, exceptionally well-cut specimens may command a slight premium.
Clean your square emerald cut lab-grown diamond regularly using warm water, mild dish soap, and a soft toothbrush. Gently scrub all surfaces, including underneath where oils and debris accumulate. Rinse thoroughly and pat dry with a lint-free cloth. Have your diamond professionally cleaned and inspected annually to ensure prongs remain secure and the setting maintains its integrity.
Without specialized equipment, lab-grown square emerald cut diamonds cannot be visually distinguished from natural diamonds. They have identical physical, chemical, and optical properties. Labrilliante's lab-grown diamonds come with certification that identifies them as laboratory-created, but this requires professional equipment to verify—to the naked eye and even to most jewelers' loupes, they appear identical to mined diamonds.
Square emerald cuts typically have a smaller face-up appearance compared to round brilliants of the same carat weight due to their deeper pavilions. However, their geometric shape creates an impression of architectural precision that many find more visually striking than the apparent size alone. Labrilliante offers advice on selecting ideal proportions to maximize the visual impact of your square emerald cut diamond.
The controlled environment of laboratory diamond creation actually allows for exceptional clarity in square emerald cuts. Since this cut emphasizes transparency and is less forgiving of inclusions, Labrilliante's lab-grown process is particularly advantageous—we can consistently produce high-clarity diamonds ideal for this demanding cut without the environmental impact of mining.
