'Exceptional' 29.6-carat blue diamond found in South African mine
LONDON (Reuters) - A 29.6-carat blue diamond, one of the rarest and most coveted in the world with a possible price tag of tens of millions of dollars, has been discovered at a South African mine by Petra Diamonds.
The miner said the "exceptional" acorn-sized diamond, small enough to fit into the palm of a hand, was unearthed at the Cullinan mine near Pretoria.
The mine, owned by the company since 2008, was also where the Cullinan Diamond was found in 1905 - described as the largest rough gem diamond ever recovered and weighing 3,106 carats.
Other notable diamonds found in the mine include a 25.5 carat Cullinan blue diamond, found in 2013 and sold for US$16.9 million (S$21.6 million), and a diamond found in 2008, known as the Star of Josephine, which was sold for US$9.49 million.
