Emeralds, renowned for their lush green hues, have captivated humanity for centuries. However, when the vibrant green tones transform into shades of blue, a rare and enigmatic gem emerges. In this comprehensive guide, we will unravel the mystery of blue emeralds, exploring their unique characteristics, historical significance, and the answer to the intriguing question: What is a blue emerald called?
Emeralds and Their Signature Green Brilliance
Emeralds, a variety of the mineral beryl, are prized for their intense green coloration, which is caused by the presence of chromium and vanadium. The vibrant green hues are the defining characteristic of emeralds and have made them one of the most sought-after gemstones throughout history.
The allure of emeralds lies not only in their mesmerizing color but also in their historical and cultural significance. Mined in various parts of the world, including Colombia, Zambia, and Brazil, emeralds have adorned the crowns of royalty and found their place in the world’s most famous jewelry collections.
The Mystery of Blue Emeralds: A Rare Phenomenon
While green is the predominant and accepted color for emeralds, there are rare instances where these gemstones exhibit shades of blue. This occurrence is exceptionally uncommon and attributed to specific geological conditions during the formation of the emerald crystals.
The blue hue in emeralds is thought to result from the presence of iron in addition to chromium and vanadium. The interplay of these elements under unique geological circumstances can cause emeralds to display a range of blue shades, adding an extra layer of mystique to these already enchanting gemstones.
What is a Blue Emerald Called? The Terminology Dilemma
The gemological world grapples with the nomenclature for blue emeralds. Unlike other colored gemstones, where distinct names often define variations in hue, the blue variety of emerald lacks a universally accepted term. Gemologists and jewelers commonly refer to these stones as “blue emeralds” to describe their anomalous coloration.
However, this nomenclature can be misleading, as it suggests a deviation from the traditional green rather than an intrinsic characteristic of the gemstone. Some experts prefer the term “blue beryl” to emphasize that the stone belongs to the beryl family, which includes emeralds, aquamarines, and other varieties.
Despite the lack of a standardized name, the beauty and rarity of blue emeralds make them highly prized by collectors and connoisseurs. The ambiguity surrounding their nomenclature adds to the allure and intrigue of these exceptional gemstones.
Characteristics of Blue Emeralds: A Closer Look
Blue emeralds share many characteristics with their green counterparts, yet their distinct coloration sets them apart. Let’s delve into the key features that define blue emeralds:
Color Range:
Blue emeralds can exhibit a spectrum of blue hues, ranging from pale sky blue to deeper shades reminiscent of the ocean. The intensity and saturation of the blue color contribute to the overall value and appeal of the gemstone.
Inclusions:
Similar to green emeralds, blue emeralds may contain visible inclusions known as “jardin,” a French term for garden. These inclusions are often considered a part of the gem’s character and can even be used to distinguish natural emeralds from synthetic ones.
Crystal Structure:
Blue emeralds, like their green counterparts, belong to the hexagonal crystal system. The presence of chromium, vanadium, and iron impurities within the crystal lattice gives emeralds their distinctive coloration.
Hardness:
With a hardness of 7.5 to 8 on the Mohs scale, blue emeralds are relatively durable. However, like all gemstones, they require proper care to prevent scratches and damage.

Geological Conditions: The Making of Blue Emeralds
The formation of blue emeralds is a geological phenomenon that occurs under specific conditions. These conditions involve the presence of not only the elements that give emeralds their green color (chromium and vanadium) but also iron, which imparts the blue hue.
The intricate dance of these elements takes place deep within the Earth’s crust, where beryl crystals undergo a metamorphic process. The introduction of iron, in addition to chromium and vanadium, creates the unique circumstances that result in the emergence of blue emeralds.
It’s worth noting that the geological rarity of these conditions contributes to the scarcity of blue emeralds, making them a truly exceptional and sought-after gemstone.
Historical Significance: Blue Emeralds in Culture and Lore

Protection and Royalty:

Blue Emeralds vs. Other Blue Gemstones: A Comparative Analysis
The world of gemstones boasts a variety of blue-hued treasures, each with its unique characteristics. While blue emeralds share a common color with other blue gemstones, distinguishing factors set them apart. Let’s explore how blue emeralds compare to some of their blue counterparts:
Blue Sapphire:
Blue sapphires, another variety of corundum, are known for their hardness and vivid blue hues. While blue emeralds and blue sapphires both exhibit blue colors, their chemical compositions and crystal structures differ. Blue emeralds are a type of beryl, while blue sapphires are a type of corundum.
Aquamarine, also a member of the beryl family, is celebrated for its tranquil blue to blue-green hues. The primary distinction between aquamarine and blue emeralds lies in their color range and the presence of chromium. Aquamarines lack the intense green hues characteristic of emeralds.
Blue topaz, a silicate mineral, is commonly heat-treated to achieve its blue color. While blue topaz exhibits a vibrant blue hue, it lacks the chromium and vanadium impurities found in blue emeralds. Blue topaz is often more affordable and readily available.
