Our Company

EMCO Gem Inc. is a global company that specializes in buying, selling and cutting the finest green emeralds from Colombia. Our distinguished principles cumulatively possess more than 70 years of experience in emeralds and are considered pioneers of the industry. EMCO Gem is committed to spreading the appreciation of this truly unique gemstone.

Established in 2000, EMCO Gem continues to push boundaries in every aspect of the emerald business – from how and where the emeralds are sourced all the way to the hands of the perfect client. At EMCO Gem, there is no middle man – we buy directly from the mine, selecting the finest gemstones to sell to our esteemed global clientele. Specializing in singles, matched pairs and layout sets, we are a prime source for fine Colombian emeralds.

Today, the emerald industry is scattered and unreliable, and it is hard to find a steady supply of quality emeralds. With our full time on-the-ground presence in Colombia, we strive to provide a consistent and reliable supply of emeralds at the highest standards of both beauty and quality.

Cutting an emerald is an art, and we are constantly challenged with bringing out the ideal color and beauty within each unique gemstone.


Our Process

An emerald is brought to life by the artistry of its cutter. With meticulous precision and unmatched taste, our experts at EMCO turn rough and polished emeralds into distinct and individualized pieces of art. Gemstones need to be studied and understood in order to maximize color and beauty. Prior to cutting, our team of experts spends time getting to know each gemstone, creating several plans for how to shape the crystal. Once the gemstone is cut, it is then cleaned to remove any polishing powder left on the surface. During the final phase, the gemstone is treated with a clear oil and/or polymer type liquid to fill the natural fissures of the gem. The process of “oiling” has been used to enhance emeralds for centuries and remains the most effective way to improve clarity, maximizing the light dispersion through each gemstone.

Colombia is world-renowned for its emerald mines,
containing the worlds highest quality green emeralds.



Our Mine

In 2014, EMCO acquired the Itoco emerald mine and fully restored the tunnel to full operating standards. The Itoco mine is located in the Muzo formation, which is the most important emerald mining area in the Boyaca state of Colombia. It is found in the eastern range of the Andes Mountains about 100 kilometers northwest of Bogota. The Itoco emerald mine is world-renowned for having the largest deposit of Class One emeralds at an unmatched beauty.

EMCO is proud to own one of the most valuable emerald deposits, right next to the original Muzo mine. The most famous emerald producing formation from the Muzo mine runs straight through the EMCO Itoco mine, which gives the site a unique geological presence of emerald producing shale and breccia. State of the art mining techniques and a newly built camp site for miners have led to new discoveries every day.
