OUR TRACEABILITY GUARANTEE
We are the only gem producer in the world equipped to supply a complete gemstone report on the unbroken chain of custody for our emeralds after mining.
We use integrated IT systems in the mines to track the date, place and time of extraction and the shape and weight of each crystal.
Since 2018, we have achieved the Quality Systems Management ISO 9001 given every year, granted by Bureau Veritas, certifying the internal transformation and logistics processes that allow us to guarantee the origin and traceability of the stones throughout the emerald value chain.
This 'passport' for the stone comes complete with photographs. The certificate also provides details of the rough and the final state of the emerald and what treatment has been utilized.
The Muzo Mines comprise 5 mining shafts: Tequendama, Catedral, Volvere, Puerto Arturo and La Rampa.
For each of our emeralds, our exclusive traceability certificate tracks the gemstone's 'parent' crystal, with the exact place and date of extraction, shape and weight.
The highly-skilled local gem-cutters in our Bogotá workshops have an eye for each individual emerald. They pore over the crystal to map its characteristics and plot where the stone will be carved, noting the distribution of color and the presence of inclusions. These gem-cutters are virtuosos of the classic cuts.
Each gem is meticulously indexed and linked to the 'parent' crystal it was cut from.
FINAL PRODUCT 'PASSPORT'
After expert faceting, the gemstone's final 'passport' is complete with total weight, shape, dimensions and, when applicable, clarity enhancement details.
Fracture-filling treatments are widely approved in the gem trade for stones with inclusions. Only a few emeralds require no treatment, as more than 95% of emeralds are treated with natural oils and resins.
The report is protected with original signatures, an embossed stamp and a security seal.
