'World's largest emerald' goes on display in Colombia
The largest emerald in the world has gone on display for the first time in Colombia, the country where the giant stone was originally discovered.
It has up to 15,000 carats and has been kept in its orginal form since it was found in Boyaca, around 47 miles (75km) north of Bogota, 12 years ago.
The emerald's value has been described as 'unmeasurable'.
