About Emerald Cut Ratio
Common length-to-width ratios for emerald-cut diamonds are 1.30, 1.45, and 1.60. A 1.30 ratio offers a more square appearance, while a 1.60 ratio presents a more elongated rectangular shape. The 1.45 ratio strikes a balance between square and elongated. It's important to note that fancy-cut diamonds do not have an official cut grade, so personal preference plays a significant role in selection. When choosing an emerald-cut diamond, you can refer to the cut grade reference chart below to help evaluate and select the diamond that best fits your preferences.

About Emerald Cut Diamond Colour
The colour grading of diamonds ranges from D (completely colourless, the highest grade) to Z (light yellow). Diamonds graded D to F are considered colourless, while those graded G to J are nearly colourless, with the colour becoming increasingly noticeable as you move down the scale. Generally, the closer a diamond is to being colourless, the more valuable it is, though certain colour grades, like light yellow, can have their own unique appeal.

About Emerald Cut Diamond Clarity
Clarity refers to a diamond's degree of internal and surface imperfections (known as inclusions and blemishes). Clarity grades range from Flawless (FL/IF) to Included (I1-I3). Diamonds with higher clarity grades have fewer imperfections, making them rarer and more expensive, while diamonds with lower clarity grades have more noticeable flaws, but can still display beautiful brilliance in certain cases.

FAQ
About Emerald Cut Lab Grown Diamonds
When selecting an emerald-cut lab-grown diamond, both colour and clarity are crucial due to the cut's open table and broad step facets, which make inclusions and colour more noticeable. Here are some guidelines:
Colour:
For emerald-cut diamonds, it's advisable to choose a colour grade in the G-H range. These grades ensure that the diamond maintains a beautiful appearance even at larger sizes. Diamonds within this range will appear near-colourless and offer great value for their quality.
Clarity:
Although SI1 or SI2 clarity diamonds are budget-friendly, it's best to opt for diamonds with a clarity grade of VS2 or higher. This ensures fewer visible inclusions, maintaining the diamond's clarity and aesthetic appeal. A higher clarity grade will enhance the diamond's overall brilliance and clean appearance.
When choosing an emerald-cut diamond, aim to balance your budget with the highest possible colour and clarity grades to ensure the diamond's beauty and brilliance.
Emerald-cut lab-grown diamonds are known for their rectangular outline and bevelled corners, typically featuring 57 facets that create a unique "hall of mirrors" effect. This cut style produces clear, steady light reflections, different from the sparkling brilliance of round or heart-shaped diamonds. Due to its open faceting, the emerald cut places higher demands on colour and clarity, as internal characteristics are more visible. This cut highlights the diamond's elegance and vintage charm, making it a classic and noble choice, especially for those seeking a simple yet sophisticated style.
To authenticate lab-grown diamonds, you should first rely on professional certifications such as those from GIA (Gemological Institute of America) or IGI (International Gemological Institute). Lab created diamonds share the same chemical and physical properties as natural diamonds, but specialised instruments like spectrometers can detect subtle differences by examining internal structure patterns or using ultraviolet light. Additionally, lab-grown diamonds often have specific marks, such as laser inscriptions, to confirm their identity. Choosing reputable suppliers and requesting certification reports during purchase are crucial steps in verifying the authenticity of lab-grown diamonds.
Lab-grown diamonds often surpass natural diamonds in quality. This is because the production process in a laboratory under precisely controlled conditions can significantly reduce the inclusion of impurities, ensuring the diamonds' purity and colour consistency. Unlike natural diamonds that take billions of years to form deep within the Earth and may contain natural flaws, lab-grown diamonds benefit from this controlled environment, often resulting in higher clarity and better cut quality. Consequently, lab created diamonds can offer superior options in terms of visual appeal and technical characteristics compared to traditional natural diamonds.
Lab-grown diamonds are synthetic diamonds created under laboratory conditions. This process mimics the natural conditions under which diamonds are formed within the Earth and is primarily achieved using High-Temperature High-Pressure (HTHP) or Chemical Vapor Deposition (CVD) techniques.
HTHP: In this method, carbon elements are subjected to high temperatures and pressures that simulate the Earth's crust conditions, transforming the carbon into diamonds.
CVD: This method involves decomposing carbon source gases in a gas mixture and depositing the carbon onto a specific substrate to grow the diamond.
Both techniques produce lab diamonds with the same structure and optical properties as natural diamonds, offering high-quality and affordable options.
Lab-grown diamonds, also known as synthetic or lab-created diamonds, are gemstones scientifically synthesised under controlled conditions to have the same chemical structure and physical properties as natural diamonds. Unlike natural diamonds, which are formed over billions of years deep within the Earth, lab-grown diamonds are produced much faster and more environmentally friendly. The production process is also more cost-effective and ensures the diamonds are conflict-free. While visually and structurally indistinguishable from natural diamonds, lab diamonds offer a more sustainable and economical alternative.
