Catalogue Note

"The described emerald of 11.038 ct exhibits an attractive and saturated green colour combined with a fine purity.

The few tiny inclusions found by microscopic examination represent the hallmarks of Colombian emeralds from the famous mining areas Muzo, Coscuez, and Chivor, all located in the green foothills of the Cordillera Oriental in the Colombian Andes. Its attractive and saturated green colour is due to a combination of well-balanced trace elements in the stone, which are typical and characteristic for the finest emeralds of Colombia.

In addition to these qualities, this emerald shows no indications of clarity modification in fissures at the time of testing, which is a further sign of rarity".
