The Geological Origins of Colombian Emeralds
Colombian emeralds are praised worldwide for their exceptional quality and deep green color. Emerald mines from Colombia are some of the most lucrative mines in the world.

The Incas used emeralds in their jewelry and religious ceremonies for over half a century. Colombian emeralds, with their unique deep hues, command fascination and high prices, making them stand out in necklaces, rings, earrings, and bracelets.
Legendary Colombian Emerald Mines
There are two main mining districts in Colombia: Muzo and Chivor. The Muzo mine is also called the “Emerald Capital of the World”. Emeralds from this mine are known to have the deepest and richest color. Emeralds from the Chivor mines have a more blueish-green hue. Both mines are still active today and produce 70-90% of the emeralds in the global market. The vivid green color of Colombian emeralds comes from the presence of trace elements like chromium and vanadium. The most desirable emeralds from these mines will have the highest clarity and the least number of visible inclusions.

4C’s of Columbian Emeralds
When buying emeralds, it's essential to consider the four Cs: cut, clarity, color, and carat weight, to ensure you choose a high-quality gemstone. Emerald belongs to the beryl family. In regards to the atomic structure of an emerald, high levels of chromium, in combination with low levels of iron, may result in crystallographic stress fractures, lowering the clarity of vivid green emeralds. Emeralds are considered type III gemstones since they always include some inclusions. Inclusions in emeralds are known as “jardin''. Jardin is French for Garden, gemologists see these slight imperfections resembling a garden's intricate patterns. When evaluating an emerald's clarity, we suggest looking for an emerald with a clarity grade of SI1 or above.
When it comes to an emerald color, the iconic green in emeralds can vary from a blueish-green to a true green, to a yellowish-green. Colombian emeralds primarily owe their incomparable and intense green color to chromium, the same element that gives ruby its distinctive red hue. This unique chromophore while positive in respect to color can harm clarity. Colombian emeralds are the most desirable emeralds because they are known to have a vibrant bluish-green.
The most popular cut for an emerald gemstone is an Emerald Cut. This is because emeralds are known to be “brittle” by nature which makes them easily susceptible to fractures. By cutting emerald gemstones in an emerald cut, it maximizes clarity, enhances color, and maintains the structural integrity of the gemstone.
When it comes to carat, it depends on the type of creation you are seeking. For emerald rings, we suggest starting at least at 3-carat. Finding natural Colombian emeralds with a vibrant blueish-green hue a few inclusions are extremely rare. Prices for Colombian Emerald jewelry ranges for $10,000 to $100,000+ depending on the size and quality of the emerald, setting and provenance.
