The photo shows a 1,111-carat diamond. The gem, only second in size to the Cullinan diamond which was unearthed in South Africa in 1905, was mined by Lucara Diamond Corp, a Canadian diamond producer and owner of the mine. The stone was recovered from its Karowe mine, about 500km north of the capital, Gaborone. It is the biggest diamond to be discovered in Botswana and the largest find in more than a century. The stone is yet to be evaluated. (Photo/Agencies)
