Historians and archaeologists can date early Colombian Emerald mining back to around 500 A.D. Indigenous Indians north of the capital city Bogotá, are believed to have mastered drilling techniques, simple shaping but never developing or attempting lapidary skills such as faceting.
The change in lapidary skills took place when Christopher Columbus and the Spanish conquistadors arrived, who can be given credit with discovering and trading what we now know as Colombian emeralds.
Today the emerald mining area of Colombia is primarily made up of small artisanal mines staffed by locals. Over the last decade several multinationals have begun to invest in the area, and now one international player is in operation.
The geology of each mine is unique to the mine itself, and different mines yield stones of a different character, the Muzo mine is known to produce large crystals of a pure green colour, a trait it shares with the nearby Cunas mine.
Emeralds from Coscuez are known for their unique hue, while in the eastern emerald belt some distance away the mine at Chivor is known for its exceptional crystal which gives its stones exceptional brilliance.
We are currently looking at some opportunities with ‘Marque’ mines that have produced high-quality stones in the past with good prospects for further exploitation and improved cost efficiencies.
