For centuries, Muzo has been synonymous with the world’s finest emeralds. Nestled in the lush mountains of Boyacá, Colombia, the legendary Muzo mine remains the most important source of exceptional emeralds.

Over a decade ago, Muzo Emerald entered a new era. Through a fully integrated Mine-to-Maison model, the company is elevating standards of quality, consistency and traceability. Anchoring this approach is its globally recognized Certificate of Traceability and Origin, ensuring transparency across the entire value chain.

At the same time, Muzo is reshaping market dynamics through its international auction platform for both rough and polished emeralds, while introducing a new color signature, Misty Green™ by Muzo Emerald.

Blending heritage with innovation, Muzo is not only preserving its legacy, it is setting a new benchmark for the emerald industry — one where craftmanship, transparency, origin and access are as valuable as the stones themselves.

Traceability as a foundation

Traceability is one of the founding pillars of Muzo. Since 2018, the company has been ISO 9001-certified by Bureau Veritas, ensuring rigorous quality management across the entire supply chain. From extraction to the final polished gemstone, every step is managed with precision and discipline, documented, and verified. Therefore, every stone Muzo mines and cuts is accompanied by a Muzo certificate.

Muzo’s Mine-to-Maison model guarantees full transparency and accountability. Each stone can be traced back to its origin, offering a level of confidence that is fundamental in today’s market.

To reinforce this commitment, Muzo has introduced a digital verification tool, allowing clients to authenticate stones or confirm Muzo origin directly via its website. This innovation strengthens trust among both trade professionals and end consumers.

A signature identity: Misty Green™

Muzo emeralds are globally renowned for their exceptional color and clarity. Today, the brand is refining its identity through distinct color signatures. Muzo Green remains the historic benchmark, distinguished by its depth, intensity and vivid saturation. In contrast, Misty Green™ — which the company introduced in May 2025 — presents a contemporary expression: lighter, luminous and refined, evoking the soft mist of the Andes. Balancing brightness, sophistication and versatility, Misty Green has quickly established itself as a defining signature within the Muzo portfolio. In less than a year, Misty Green™ has crystallized into a distinct category, with strong and growing demand reflecting its broad industry acceptance.

Evolving distribution and market access

As Colombia’s foremost emerald mining company, Muzo continues to evolve its distribution strategy to stimulate both Colombian and international markets. Operating a fully integrated vertical model, Muzo maintains full oversight of its sales channels as a core pillar of its strategy. With offices in New York and Geneva, the company conducts direct sales while sustaining a strong presence at major international trade shows.

Throughout the year, Muzo also hosts a series of invitation-only auctions for both rough and polished emeralds in Bogotá, New York, Bangkok, Hong Kong and Geneva. Participation is reserved for qualified buyers, companies within the gemstone and jewelry industry, and a select group of collectors and investors, who are invited to apply by contacting auction@muzoemerald.com or by submitting an application via the official muzo.co website.

The Muzo cut

At the heart of Muzo’s innovation lies the Muzo cut, a proprietary cutting approach it developed in-house. Departing from traditional methods that favor weight retention, the Muzo cut is guided by the pursuit of ideal proportions and perfect symmetry, revealing each stone at its most exceptional. The result is a heightened expression of color, light and brilliance, achieving a harmonious balance from table to pavilion.

“At Muzo, the precious emerald becomes the medium through which light and color are mastered, revealing an artistry instantly recognizable as Muzo,” says Aricie de Sainte Preuve, the company’s head of marketing.

Precision mining for consistent production

Muzo has transformed its operations through significant investment in advanced underground mining technology. The transition from traditional methods to a highly structured, technology-driven approach has dramatically improved both safety and efficiency.

Reinforced tunnels, advanced ventilation systems, and precise geological mapping — supported by specialized machinery — enable highly controlled extraction and optimal recovery rates. Through the use of the cut-and-fill method, Muzo minimizes waste while preserving the integrity of its natural environment.

Spanning a 55-hectare concession and sustained by over four centuries of continuous production, Muzo’s mining operations offer a rare level of long-term stability within the colored-gemstone sector. Currently reaching depths of 170 meters, the mine continues to expand with confidence.

Exceptional emeralds are consistently recovered across all levels, reflecting remarkable uniformity in both size and quality. Real-time digital monitoring and underground connectivity ensure full transparency, operational integrity, and security at every stage.

Beyond the mine: Creating lasting impact

Muzo’s vision extends beyond gemstones. Through the Muzo Foundation, the company invests in the well-being and the development of local communities in Boyacá. Its initiatives include education programs, improved access to healthcare, and sustainable economic development projects such as the Abuelo Program, egg farming, and diversified agriculture.

Importantly, Muzo is also promoting greater inclusion within the mining sector by creating employment opportunities for women, historically underrepresented in the industry.

Setting the standard for the future

By uniting heritage, innovation and responsibility, Muzo Emerald sets a new benchmark for excellence in the emerald industry.

From mine to market, every stone embodies precision, transparency and enduring value — establishing Muzo not only as a historic name, but as the future standard for Colombian emeralds, colored-gemstone mining, and sustainable regional development.
