PETRA CELEBRATES MAIN MARKET MOVE WITH RECORD SALE
PETRA Diamonds has achieved the highest price per carat of any rough diamond it has ever sold. The 4.8 carat blue stone was sold for $1.45m (£920,000) just hours before Petra’s shares started trading on London’s main market yesterday, graduating from Aim. Chief executive Johan Dippenaar is pictured at the Cullinan mine, where the stone was found.
