How to Identify Real Emerald Stone?

Emeralds have long been treasured for their beauty and symbolism. They are associated with attributes like love, rebirth, and good fortune. Naturally occurring emeralds are rare and command high prices, making them a desirable target for counterfeiters. To avoid being deceived, it’s essential to equip yourself with knowledge and learn how to identify real emerald stones.

How to Identify Real Emerald Stone

Identifying a real emerald stone requires a keen eye and attention to detail. Here are key factors to consider when determining the authenticity of an emerald:

1. Color: The Allure of Green

One of the most distinguishing features of emeralds is their rich green colour. However, not all green gemstones are emeralds. Genuine emeralds possess a specific hue that sets them apart. Look for a deep, intense green with a slight bluish undertone. Avoid stones that exhibit a pale or yellowish-green colour as they are likely imitations or lower-quality emeralds.

2. Clarity: The Window into Authenticity

Real emeralds often contain inclusions, which are natural formations inside the stone. These inclusions, known as “Jardin” (French for garden), are tiny internal fractures or mineral deposits. In fact, emeralds are known for their unique “jardin,” which adds to their character and authenticity. If you come across an emerald with exceptional clarity and no visible inclusions, exercise caution, as it might be a synthetic or an imitation stone.

3. Cut: The Art of Enhancing Brilliance

The cut of an emerald greatly influences its brilliance and overall appearance. Genuine emeralds are typically cut to maximize their colour and minimize imperfections. The most popular cut for emeralds is the “emerald cut,” which features rectangular facets and cropped corners. This cut highlights the stone’s colour and allows light to pass through it, creating a captivating effect. Be wary of emeralds with poor or inconsistent cuts, as they may be imitations.

4. Carat Weight: The Size Factor

Carat weight refers to the size of a gemstone, and it plays a role in determining its value. However, when it comes to emeralds, carat weight alone is not a reliable indicator of authenticity. Genuine emeralds can vary significantly in size, and larger stones may command higher prices due to their rarity. Focus on other factors, such as colour, clarity, and cut, to determine the authenticity of an emerald, rather than relying solely on its carat weight.

5. Refractive Index: The Magic of Light

The refractive index measures how light behaves as it enters and exits a gemstone. Genuine emeralds have a relatively high refractive index, resulting in a unique brilliance and sparkle. To test the refractive index of an emerald, you can use a refractometer, a specialized tool commonly found in gemological laboratories. This test helps distinguish between real emeralds and imitations that may have different refractive properties.

6. Hardness: The Resilience Test

Emeralds belong to the beryl family of minerals, which includes other gemstones like aquamarine and morganite. Genuine emeralds have a hardness of 7.5 to 8 on the Mohs scale, indicating their durability. While emeralds are relatively hard, they are still susceptible to damage from rough handling or high impact. Be cautious if the emerald scratches easily or shows signs of wear, as it may not be genuine.

7. Origin: Unraveling the Source

The origin of an emerald can provide valuable insights into its authenticity and value. Some regions are renowned for producing high-quality emeralds, such as Colombia, Zambia, and Brazil. Emeralds from these regions often command a premium due to their exceptional colour and clarity. However, determining the origin of an emerald solely by visual inspection is challenging. Gemological laboratories employ advanced techniques, including spectroscopy, to identify the source of an emerald accurately.

8. Certification: Trustworthy Assurance

To alleviate doubts and ensure the authenticity of an emerald, seek stones accompanied by reputable gemstone certifications. Certifications from recognized gemological institutes, such as the Gemological Institute of America (GIA) or the American Gemological Laboratories (AGL), provide an assurance of quality and authenticity. These certifications detail the gemstone’s characteristics, including colour, clarity, cut, and any treatments it may have undergone.


How can I tell if an emerald is real just by looking at it?

To determine if an emerald is real, you should consider various factors such as colour, clarity, cut, and inclusions. Real emeralds typically have a deep, intense green colour, visible inclusions, and a well-cut shape. However, it’s challenging to assess the authenticity of an emerald accurately without professional assistance or specialized equipment.

Can synthetic emeralds be mistaken for real emeralds?

Yes, synthetic emeralds, also known as lab-created or man-made emeralds, can be mistaken for real emeralds. These synthetic stones possess similar chemical and physical properties as natural emeralds, making them difficult to distinguish without gemological testing. To identify a synthetic emerald, professional gemological analysis or the presence of specific lab-grown indicators is required.

Are there any treatments commonly applied to emeralds?

Yes, treatments are commonly applied to emeralds to enhance their colour and clarity. One of the most prevalent treatments is oiling, where colourless oils or resins are used to fill surface-reaching fractures and enhance the stone’s appearance. This practice has been used for centuries and is generally accepted within the gemstone industry. However, it’s crucial to disclose any treatments when buying or selling emeralds.

What is the best way to clean and care for emerald jewellery?

To clean emerald jewellery, gently wipe the surface with a soft, lint-free cloth dampened with mild soapy water. Avoid using ultrasonic cleaners or harsh chemicals, as they can damage the stone. Additionally, emeralds should be protected from sharp blows, extreme temperatures, and prolonged exposure to sunlight. It’s advisable to remove emerald jewellery before engaging in activities that may subject it to potential damage.

How much do real emeralds cost?

The cost of real emeralds varies widely based on factors such as colour, clarity, carat weight, cut, and origin. High-quality emeralds can command prices comparable to or even surpass diamonds. Exceptional emeralds with intense green colour, minimal inclusions, and larger carat weights can be extremely valuable. It’s recommended to consult with reputable jewellers or gemologists to obtain accurate pricing information.

Can emeralds be passed down as family heirlooms?

Certainly! Emeralds, with their enduring beauty and significance, make excellent family heirlooms. Passing down an emerald from one generation to the next preserves not only the gemstone’s material value but also its sentimental and historical value. Proper care and maintenance ensure that these precious heirlooms can be cherished for many years to come.


Mastering the art of identifying real emerald stones empowers you to make informed decisions when purchasing these precious gemstones. Remember to consider factors like colour, clarity, cut, and inclusions, while also seeking professional gemological certifications when possible. By acquiring knowledge and honing your observation skills, you can confidently navigate the world of emeralds and cherish the beauty of genuine stones.

Remember, when it comes to emeralds, knowledge is your greatest ally. Now that you’re equipped with the essential insights on how to identify real emerald stones, venture forth with confidence and find the perfect emerald that captures your heart.
