The world’s second-largest miner, Rio Tinto announced its first rough diamond tender for 2014, which consists of 124 lots of the special gems including a range of rare natural pink precious rocks from its Argyle mine in Western Australia.

According to Patrick Coppens, general manager of sales for Rio Tinto Diamonds, the global demand for precious stones continues to be strong.

Experts predict that rough diamond production will grow at an average annual rate of 4.8% from now until 2018, reaching a peak level of 169 million carats and a production value of $19.6 billion.

By 2019, however, the report authors expect average rough diamond production to begin dropping 1.9% a year, levelling off at 153 million carats in 2023, with a production value of $18.4 billion.
