In this emerald cut diamond buying guide, we will explore essential aspects of the emerald cut, including its characteristics, features, and how it appears when set in different settings. Here's everything you need to know before purchasing one.

The Characteristics of an Emerald Cut

An emerald cut is distinct with its elongated rectangular shape and trimmed corners, creating a mesmerising hall-of-mirrors effect. Its step-cut faceting allows for broad, flat planes known as "steps," which reveal the stone's internal clarity and magnificent sparkle. Use our emerald cut diamond buying guide to find out if this is the perfect diamond cut for you.

Elegant Shape and Cut

The silhouette of the emerald cut is perfect for those seeking a sophisticated and classic look. The straight lines and trimmed corners of this diamond contribute to its architectural appeal, providing a touch of structured beauty to the overall design.

While some emerald cut diamonds are perfectly square, most are elongated. This creates a flattering rectangular shape that enhances the diamond's overall appearance. The elongated silhouette adds a sense of grace and sophistication to the diamond when set in a ring or other piece of jewellery.

The diamond's elegant shape and cut make it a popular choice for those who appreciate understated luxury. Its clean lines and timeless design lend themselves to a variety of styles and settings, making it a versatile choice. When you choose this diamond cut, you are embracing a look that will never go out of style, always exuding a sense of sophistication and refined beauty.

Hall of Mirrors Effect

The emerald cut features a fascinating optical phenomenon known as the "hall of mirrors" effect. This effect is a result of the diamond's step-cut faceting pattern, which creates a unique visual display. The step facets, with their long and uninterrupted surfaces, are responsible for this captivating illusion.

As light enters and interacts with the diamond, it reflects off the step facets, creating a series of reflections and refractions. These reflections bounce back and forth, creating a dazzling display of lights, giving the impression of a "hall of mirrors." This effect adds depth and dimension to the diamond, showcasing its intricate beauty with understated elegance.

The "hall of mirrors" effect is one of the distinct and enchanting qualities of an emerald cut diamond. When you wear or admire this type of diamond, you'll be captivated by the way it sparkles and shimmers, truly appreciating the intricate facets and the optical magic it creates.

Internal Clarity

When examining an emerald cut solitaire stone, you'll notice that its large, open table and step-cut faceting offer a clear view of the diamond's internal characteristics. Prioritise clarity to ensure that any inclusions or blemishes are not overly noticeable to the naked eye.

In your search for the perfect diamond, consider choosing a clarity grade of SI1 (slightly included) or higher. This clarity grade provides an excellent balance between quality and value, allowing you to enjoy a diamond with minimal imperfections that may impact its overall beauty. 


It's natural to think that a larger carat weight means a bigger diamond. However, carat weight alone doesn't solely determine the diamond's overall beauty or value. While a larger carat size can indeed make a diamond visually striking, aspects like cut quality, clarity, and colour also play important roles in determining a diamond's beauty and worth. 

So, when assessing diamonds based on carat weight, be sure to consider the balance of all these factors to find a diamond that not only looks impressive in size but also exceptional brilliance and quality.

Emerald Cut Diamond Buying Guide: The Importance of Cut Quality

When it comes to a step-cut diamond, cut quality determines its brilliance, fire, and overall visual appeal. Like choosing any diamond, several factors affect the brilliance of this design.


Focus on the ideal length-to-width ratios and the balanced arrangement of step facets. A well-proportioned diamond will have these features, resulting in a visually pleasing and balanced result. 

To ensure the best outcome, the recommended length-to-width ratio for an emerald diamond is between 1.30 and 1.50. This range allows for a flattering and visually balanced appearance, highlighting the diamond's elongated shape while maintaining a sense of harmony.


Symmetry refers to how well the diamond's facets align and interact with each other. Examine how well its facets align and interact with each other. Excellent symmetry is key to ensuring that no facets overpower others, resulting in a harmonious and visually appealing diamond. 

When you choose a diamond with exceptional symmetry, it allows the diamond to exhibit its full potential for brilliance and sparkle. The balanced and symmetrical arrangement of facets creates a sense of unity and harmony, enhancing the overall beauty and visual appeal of the stone.


When considering the polish of a diamond, focus on the quality of the surface finish. Specifically, a diamond with excellent polish will offer you a smooth and flawless surface. This smoothness plays a significant role in maximizing the diamond's brilliance, allowing light to reflect and refract beautifully, ultimately enhancing its overall beauty. 

This ensures that your diamond radiates a stunning and captivating sparkle, making it a truly eye-catching choice.
