The world's largest emerald on display in Colombia

The world's largest emerald is on display in Colombia, a country of its discovery. This specimen has been kept from 15,000 carats in its original form since its discovery, 12 years ago.

The place where he appeared incredulous eyes of the authors of the discovery is the area of Boyaca, 47 miles north of Bogota. Impossible to make precise estimates for a treasure like that, to the point that it is preferred to label its value as 'not measurable'.
