A blue diamond weighing a staggering 122.52 carats has been unearthed in South Africa – expected to be the most valuable ever found.
Petra Diamonds Ltd said it had recovered the ‘exceptional’ gem at its Cullinan mine, on the outskirts of Pretoria, just months after it sold a 29.6 carat blue diamond from the same mine for more than £14 million ($25 million).
The jewel – which is about the size of a strawberry – is so pure that it is expected to eclipse the current world’s most expensive diamond – a 507-carat white diamond dug from the same mine that sold for $35 million in 2010.
Blue diamonds are considerably more valuable than their white cousins.
