Rio Tinto Limited (ASX:RIO) says a tender of its rare diamonds has achieved the highest average price per carat since the tender began in 1984.
The miner’s 30th anniversary collection of 54 rare pink and red diamonds from its Argyle diamond mine also attracted a record amount of bids.
Rio Tinto received more than 600 bids for the rare diamonds and advises the successful bids were submitted from ten countries.
While the company keeps the total value confidential it says the overall prices for Argyle’s signature pink diamonds have more than tripled since the year 2000.
Rio Tinto believes these results reflect the global appeal and enduring value for increasingly rare and iconic gems.
Rio Tinto reported a net profit of $4.54 billion in the first half of the 2014 calendar year.
