Everything you need to know about Emerald Gemstone
The exact shade of green that distinguishes an emerald from green beryl is a subject of debate among those who specialize in studying precious stones.
Most gemologists, gemological labs, and coloured stone sellers will refer to a stone as green beryl when the colour of the stone is "too light" to be categorized as an emerald. However, even among members of that group, there is a diversity of opinion over what constitutes "too light."
Beryl is a mineral species that also comprises aquamarine in addition to beryls of various hues, including the green-to-blue-green variant known as emerald. Emerald's colour ranges from green to bluish-green.
Professional gemologists have different opinions on how much green is required to classify a stone as an emerald or a less costly green beryl. As a result, green beryls tinted by chromium are often incorrectly labelled emeralds by those in the trade.
When a stone's hue is "too light" to be categorized as an emerald, most gemologists, gemological labs, and coloured stone traders will refer to it as green beryl instead. However, there is disagreement even within that subset over what constitutes "too light."
The Gemological Institute of America (GIA) employs lab-graded reference stones of a similar hue to establish if a stone qualifies as an emerald.

The vibrant green of an emerald has calmed minds and inspired creativity for millennia. The ancient Greek word for "green," "smaragdus," is whence its name originates. A Roman historian named Pliny the Elder wrote about emeralds in the first century AD for his book Natural History.
As he put it, "there is no greater means of healing their eyes than by staring at the emerald, its gentle, green tint calming and alleviating their fatigue and lassitude." Green has long been associated with calming emotions and reducing eye fatigue; this tradition continues today.
Even while emerald isn't the only green gem (tourmaline and peridot also exist), it is the one most often linked with images of verdant settings and deep shades of green.

The first documented emerald mines date back to Egypt, between 330 BC and the early 18th century. Cleopatra loved emeralds and wore them often in her royal jewellery.
When the Spanish conquered the New World in the sixteenth century, one of their spoils was emeralds from the area that is now Colombia. Emeralds were worn as jewellery and used in rituals by the Incas for at least 500 years before Christopher Columbus discovered them.
Since the Spanish valued gold and silver more than jewels, the latter swapped emeralds for the former. Through their commerce, the regal families of Europe and Asia were introduced to the beauty of emeralds.
The beryl family includes the emerald, the most well-known gemstone in that group. It was said that the wearer could see into the future, speak the truth, and ward against bad spells if an emerald was put beneath the tongue.
Some ailments, like cholera and malaria, were originally thought to be cured by emeralds. In addition, wearing an emerald was thought to disclose if a lover's pledge was true or false and improve one's oratory skills.
As one of the four precious stones God bestowed on King Solomon, the emerald is also associated with myth and legend. For example, there was a legend that the monarch had absolute dominion over the cosmos thanks to these four stones.
In May, its hue symbolizes the renewal of life that comes with the arrival of spring. It is also the traditional gift on the 25th anniversary of marriage.
