"The small 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 green colour is due to a combination of well-balanced trace elements in the stone, typical and characteristic for the finest emeralds of Colombia...

An emerald of this size containing only a minor amount of oil in fissures can be considered rare. A natural emerald from Colombia of this size and quality is rare and exceptional".
