Introduction:
Emeralds are highly sought-after precious gemstones, renowned for their vibrant green color and unique characteristics. If you’re considering purchasing an emerald or want to verify the authenticity of a piece in your collection, here are some ways to tell if an emerald is real.
1. Examine the color:
Authentic emeralds come in various shades of green. The most valuable ones display a deep, vivid green hue with a hint of blue. Fake emeralds may appear too perfect in color, while natural ones will have subtle variations in shade, known as the “jardin.”
2. Look for inclusions:
Natural emeralds tend to have imperfections or inclusions within the stone. These can be small fractures, gas bubbles, and minerals – collectively known as the “jardin” (garden) – which give each emerald a unique pattern. Synthetic or imitation emeralds tend to be free of these inclusions.
3. Check the cut and shape:
Real emeralds are often cut into rectangular “emerald” or “step” cuts to showcase the stone’s brilliance. Fake emeralds might be poorly cut or exhibit unusual shapes that wouldn’t typically be seen in genuine pieces.
4. Observe light play:
Natural emeralds exhibit a characteristic called “pleochroism,” meaning they show different colors when viewed from various angles under different light sources. One way to check for this is by rotating the stone under a light source such as a penlight or desk lamp and observing any color shifts.
5. Test for hardness:
Emeralds have a Mohs hardness of 7.5-8 – which means they can scratch glass and quartz but can be scratched by topaz or diamond. Performing a scratch test may help distinguish between real emeralds and fake ones made from softer materials like glass. However, be cautious not to cause damage or decrease the value of the stone.
6. Consult a professional:
When in doubt, seek the advice of a professional gemologist or certified appraiser. These experts possess the necessary tools and knowledge to determine an emerald’s authenticity and value.
Conclusion:
Determining the authenticity of an emerald can be challenging due to various imitation and synthetic stones on the market. By examining color, inclusions, cut, light play, and hardness – and with the help of a professional – you can confidently assess whether an emerald is genuine or not.
