The family of emeralds boasts several types of rough emeralds, each possessing a unique quality of its own. Inclusions, color, origin, and clarity define them.
Zambian Emeralds
The Zambian emeralds are famous for their deep green hues and high saturation, which is why they became so popular today. Most of these stones come with inclusions of pyrite and iron, which gives them a darker color than traditional Colombian stones. However, they also have comparable quality and often come at a lower price.
Colombian Emeralds
Emeralds from Colombia are among the most sought after in the world when it comes to their quality and color. Most of them come from the Muzo and Chivor mines, which produce stones of a lighter green shade, such as grass green. Colombian emeralds have a historical reputation for being of superior quality in terms of clarity and color. They exhibit typical inclusions like rutile and carbon. The most famous Colombian emerald mine is Muzo, known for producing stones with unparalleled quality and a vivid, deep green color. The Chivor mine, another renowned source, yields emeralds with a slightly lighter hue, often featuring more inclusions. Colombian emeralds are characterized by their characteristic inclusions, such as rutile and carbon. These inclusions, while reducing clarity, enhance the stone's authenticity and shimmer through the phenomenon known as “jardin,” which means garden in French due to their plant-like appearance.
Brazilian Emeralds
Emeralds from Brazil are mined in several regions, including Minas Gerais, which come in a wide variety of colors, ranging from dark green to blue-green. While they are not considered to be of the same quality as Colombian emeralds, they are still prized for their unique hues and larger sizes. Brazilian emeralds commonly lack the characteristic inclusions of Colombian stones, but they still possess beauty and quality.
African Emeralds
Besides Zambia, emeralds are also mined across other African countries, such as Mozambique and Namibia. African emeralds exhibit varying colors and qualities, though Mozambique emeralds are increasingly gaining attention for their vibrant green color and clarity. The emeralds from Mozambique often contain inclusions of pyrite, which adds to their unique look. Although often considered of lower quality than Zambian or Colombian varieties, African emeralds include Mozambique emeralds, which are esteemed for their vibrant color and growing reputation in the market.
Synthetic Emeralds
These emeralds are manufactured in controlled environments to replicate the natural stones' chemical composition and appearance. They are typically less expensive and used to make jewelry when natural stones are more expensive and out of reach. Nevertheless, they lack the historical value and uniqueness of natural emeralds.
Although widely known and used as precious stones in making jewelry, emeralds find application across other industries beyond gemology.
Pharmaceutical Industry
Emeralds and other beryllium-based minerals act as sources of beryl, which is used to manufacture several drugs. For instance, beryl is used in making a drug for treating gastrointestinal issues. Emeralds have been used to make medicines because they are believed to produce healing rays that assist medical professionals in diagnosing and treating diseases, including eye disorders and cancer. The green stone, often called "the stone of successful marriage" and an emblem of fertility, has also been used in some ancient medicines.
Scientific and Research Tools
The high durability of emerald makes it useful for creating instruments that operate in harsh conditions, which in turn makes it useful for scientific exploration. Beryl, the mineral that makes up emerald, can be used as a probe or tip in electron microscope research and for insulating materials in nuclear reactors. Deep inside the earth, emerald is believed to be trapped within diamond crystals and brought to the earth's surface through volcanic eruptions, hence giving researchers a clear view of conditions in the earth's interior.
Abrasives
The hardness of emerald ranks 7.5 to 8 on the Mohs scale, which makes it possible to be used along with other harder materials as an abrasive. Emerald dust has been used in the past for polishing applications, but today it has been mostly replaced by synthetic diamond powders and other more effective emerald compounds.
Dies and Tool Manufacturing
The toughness and hardness of emeralds also makes them suitable for die and tool manufacturing in industrial applications. Emeralds and beryl are used in making cutting tools, dies, and molds that require high wear resistance. The durability of emerald tools leads to longer tool life and improved efficiency in machining operations, reducing the need for frequent tool replacements.
Cosmetic Industry
Emerald powder is used in several cosmetic products, such as lotions, creams, and face masks, which help to nourish and revitalize the skin. It is used in the formulation of anti-aging creams to help protect the skin from free radicals.
