The world’s second largest diamond is up for sale, but no one seems to know what the price tag is.

The Lesedi Le Rona diamond was discovered in Botswana in November last year, not far off from neighbouring South Africa where the world’s largest diamond was found in 1905.

The gem measures 1,111 carats and has been described as magnificent.

Owners remain tight lipped about its worth however interested parties can approach the company.

Botswana has earned its reputation as the world’s biggest diamond producer.

But exports declined 39% last year.

Its hope the Lesedi Le Rona diamond  will give the industry a boost.
