How to Check Purity of Emerald Stone?

Emerald gemstones are known for their captivating green hue and historical significance. Often referred to as the “gem of Venus,” emeralds have been adorning jewelry pieces for centuries. However, with the market flooded with imitations and synthetic stones, it has become crucial for enthusiasts and buyers to be well-informed about how to determine the purity of emerald gemstones. In this blog post, I will share my personal insights and experiences on how to check the purity of emerald stones, ensuring that you make an informed purchase.

Step 1: Observe the Color

Genuine emeralds boast a rich, vibrant green color that ranges from bluish-green to yellowish-green. Avoid stones that appear too light, dull, or have uneven color distribution. I’ve found that placing the emerald against a white background and under natural sunlight or a bright light source helps to better observe its true color and eliminate any doubts.

Step 2: Analyze Clarity and Inclusions

Emeralds are rarely free from inclusions, which are tiny imperfections within the gemstone. These inclusions, also known as the “garden,” lend emeralds their unique character and prove their authenticity. However, if the inclusions are too excessive, it may be a sign of a fake stone. Using a magnifying glass or loupe, closely inspect the emerald for any visible cracks, cloudiness, or unnatural patterns.

Step 3: Test for Transparency

Place the emerald on a piece of white paper and examine it under bright light. Authentic emeralds possess excellent transparency, allowing you to see through the stone to some extent. If the stone appears opaque or overly transparent, it could be a synthetic or a low-quality substitute.

Step 4: Assess the Cut

A genuine emerald is often cut into a step-cut, known as the “emerald cut,” which showcases its mesmerizing color and inclusions. If the stone is cut into facets that diminish its color or lacks precision, it might not be a pure emerald. Look for well-proportioned facets and a symmetrical appearance to ensure its authenticity.

Step 5: Examine the Origin and Certification

Knowing the origin of your emerald can play a significant role in verifying its purity. Emeralds from well-known sources such as Colombia, Zambia, and Brazil tend to be of higher quality. Furthermore, always request a gemological certificate from a reputable laboratory. A certified gemstone guarantees its authenticity, as it undergoes rigorous testing and analysis by professionals.


With these comprehensive steps in mind, you can now confidently embark on your journey to identify genuine emerald gemstones. By observing the color, analyzing clarity and inclusions, testing for transparency, assessing the cut, and examining origin and certification, you will be better equipped to make an informed purchase decision. Remember, a genuine emerald is not just a beautiful piece of jewelry but a symbol of elegance and prestige that deserves the utmost care and consideration. Happy emerald hunting!
