Emerald cut – Muzo – Boyaca, Colombia

Colombian emeralds are globally revered for their exceptional quality, bright and deep-green color, which is the result of their high chromium and vanadium content. These gems are unique because they are formed in sedimentary rocks, unlike emeralds from other parts of the world which are formed in igneous rocks. Colombia supplies approximately 90% of emeralds to the world market, mainly from the Muzo, Chivor and Coscuez mines. The quality of emeralds is divided into carving grade, cabochon grade and facet grade, with the facet grade being the best known and most sought after. Gem quality emeralds are very rare and miners often have to sift through tons of rock to find a few quality emeralds.

The most popular color of emeralds ranges from blue-green to pure green, which is associated with a bright saturation of color and a lack of overly dark green. High transparency and even distribution of color with no visible color zones are typical of valuable emeralds. If the color tends too much towards yellow or blue, the stone is not classified as an emerald but as beryl, which affects its value.

Why Colombian emeralds?

Colombian emeralds are an excellent choice due to their unique and intense green color, which is considered the most desirable in the world. These gems are highly valuable due to their origin, which includes mines such as Muzo and Chivor, which are known for their beautiful specimens. The quality of Colombian emeralds is further enhanced by their high transparency and minimal inclusions, which increases both their visual appeal and potential for long-term value appreciation.

Muzo Region

Muzo emeralds are known for their intense, vibrant green colour with subtle yellowish undertones. Muzo is the oldest and most famous mining site, having been mined before the arrival of the Spanish conquistadors in the 14th century. Emeralds from this area are usually darker and greener, often with dark spots. The mines are state property and are leased to mining companies. They are located in difficult terrain with a hot and humid climate.

Chivor Region

Chivor emeralds are characterised by their blue-green hue and are generally purer and glossier than those from Muzo. Some of the mines in Chivor are privately owned, which is unique within Colombia. They are located in difficult to access terrain with dense forests and high humidity. Chivor emeralds are often associated with pyrite crystals, which can help determine their origin.

History of Colombian emeralds

The history of Colombian emerald mines is filled with mysteries and legends. Indigenous Colombian natives mined and traded these gems long before Europeans arrived. The first European contact with Colombian emeralds occurred in 1537 when Spanish conquistador Gonzalo Jiménez de Quesada conquered the territory inhabited by the Muisca tribe. The conquistadors discovered that these gems originated from an area known as Somondoco, today's Chivor mine, which in the local language means "god of green stones."

In the 1560s, the Spaniards, began mining emeralds in the Muzo area, using the indigenous population as slave labour. However, mining was often inefficient and brutal, leading to a gradual decline in production. In 1675, the Chivor mine was abandoned, and its exact location became a mystery for over 200 years until its rediscovery in 1896 by Colombian engineer Don Francisco Restrepo.

Modern importance

Today, Colombian emeralds are considered the most valuable and sought-after on the market. The Muzo mine is regarded as the world's most significant emerald mine, producing emeralds with exceptional clarity and color. Colombian emeralds are popular among collectors and jewelers due to their unique properties and historical significance.
