Botswana unveils country's largest blue diamond find

Johannesburg, Apr 17 (AP) A big blue diamond weighing more than 20 carats has been unveiled in Botswana, where the gem was discovered. The government-owned Okavango Diamond Company on Wednesday called it the largest blue diamond ever discovered in the southern African nation.

A company statement says it is "in the very top bracket of all-time historical blue diamond finds." The bright blue colour is attributed to the mineral boron, which was present in the rocks of oceans when the diamond was formed some 1 to 3 billion years ago.

Company managing director Marcus ter Haar says just a few such blue stones have come to market in the last decade. The company says the diamond is expected to be sold near the end of the year. (AP) RS RS
