Emerald Gemology

Emerald is known as the king of emeralds. As rare as bright red rubies, fine emeralds are truly breathtaking sights. It is also one of the four precious gemstones (red, blue, emerald, and diamond) recognized by the international jewelry industry. Because of its unique green color, unique charm, and magical legends, it is deeply favored by people.

  1. The symbolic meaning of emerald-Emerald Gemology

Emeralds symbolize mercy, confidence, goodness, eternity, luck, and happiness. Wearing it will bring a person a lifetime of peace. At the same time, it is also a commemorative stone for the 55th wedding anniversary. Emerald is a very ancient gemstone, which has been used as jewelry in ancient Egypt. Emeralds are hard-to-find flawless gemstones. There must be more or fewer cracks and inclusions in emerald gemstones, and the types of crack inclusions are so complex that they are even called “gardens” by researchers.

As with many gemstones, the per-carat price of a high-quality emerald climbs rapidly with size. A high-quality 3-carat Colombian gem is worth six times as much as three 1-carat gems of equal quality.

  1. The color of emerald-Emerald Gemology

The color of emerald is very attractive. Some people use spinach green, spring onion green, and tender tree bud green to describe its color. It is green with a little yellow, and it seems to have a little blue, and even the spectrum seems to be missing some wavelengths. It is one of those gems that never tires of seeing. No matter whether cloudy or sunny, artificial or natural light, it always emits soft and rich light. This is the charm of emerald, the king of green gemstones.

Emeralds are gem-quality green beryls. Its green should reach a medium to rich green tone, that is, the color concentration should be relatively saturated. The light green one is usually called green beryl.

Beryl contains an appropriate amount of Cr2O3 (0.15~0.6%) to form emeralds. It is the most outstanding member of the Beryl family. The material belongs to high-grade gemstones. The source of color comes from a small amount of chromium oxide, which makes it appear crystal clear and beautiful green.

  1. Main producing areas of emeralds

The main producing areas of emeralds are Colombia, Russia, Brazil, India, South Africa, Zimbabwe, China, and so on. The most common emeralds currently on the international market come from three origins: Colombia, Brazil, and Zambia.

The emeralds produced in Colombia are famous all over the world for their good color, good texture, and large output. It is the largest source of high-quality emeralds in the world. The two main emerald deposits in Colombia are Muzo and Chivor. They are distributed within about 100km northeast of Bogotá, in the Cordillera Mountains. Colombian emeralds have been produced since the mid-16th century when the emerald mines were owned by Spanish occupiers. The mine was not nationalized until 1886. For centuries, the Muzo and Chivor mines have been the world’s largest supplier of high-quality emeralds, accounting for about 80% of the world’s total production of high-quality emeralds.


The emeralds produced in Colombia have long been famous all over the world. One of the lesser-known trapiche grainy emeralds is unique in the world.

Although Colombian emeralds have been synonymous with high-quality emeralds in the world for centuries, in the past two decades, with the decline of Colombian emerald production and the successive discoveries of new emerald deposits in Zambia, Brazil, and other places, the international emeralds of Colombia, Zambia, and Brazil are gradually emerging in the market, and Zambia has gradually become one of the most important emerald producing areas.

As of 2005, the annual output value of emeralds in the Kafubu area of Zambia has reached 20 million US dollars. Emerald production accounts for more than 20% of the world’s emerald supply and is on the rise. The quality of emeralds produced in Zambia is between Colombian and Brazilian emeralds. It is considered the second most economically significant source of emeralds after Colombia.


Brazil is also one of the important producers of emeralds. It was first discovered in 1554, and most of the minerals are located in the northeast, especially in Bahia. There are two output types of pegmatite type and mica schist type. Brazil’s pegmatite-type emeralds are mostly light in color, often with a bluish tinge, and have high clarity. The mica-schist-type emeralds are bright in color and have many blemishes.


Emerald deposits in Zimbabwe were discovered in 1957. The output is very large, and it has become an emerging major exporter of emeralds in the world. Emeralds from Zimbabwe are vivid green and can have bands, but the crystals are usually small and contain tremolite inclusions that are typically long, curved needles.

Mainly produced in Hotan, Xinjiang, Xinjiang emeralds are blue-green, and medium yellow-green, blue-green pleochroism. Few can reach the gem level.

The above is the characteristics and history of green gemstones introduced by Normaltan Jewelry. I hope you can have a better understanding of emeralds.
