Rio Tinto'S Diamond Drill Or Break The Auction Record.

The mining giant Rio Tinto (Rio Tinto) has exhibited 65 extremely rare diamond and red diamonds, and the company hopes that the diamonds from Western Australia can break the diamond auction record.

These diamonds come from the Argyle drill of Anglo-Australian, which produces more than 90% of the world's annual drill.

The 2015 series has 5 "hero" stones, including a 1.93 carat with a gorgeous purple shield drill and a 1.47 carat oval red drill.

RioTinto indicates that this year's election has been made.

A total of 44.14 carats, of which there are "the most dazzling" in history.

And red diamond.

These diamonds have been underground for 1 billion 600 million years, with an average price of 100~200 million per carat.

As a basic rule, the value of pink diamonds is usually more than 50 times that of white diamonds.

AlanDavies, chief executive of RioTinto diamond and mining, told Agence France-Presse during the annual diamond auction event: "this year is probably the highest value year we bid for, because we have some very beautiful red diamonds with unique color and cleanliness.

They are so rare, because one hand can put down all the flour drills, while red diamonds are numbered, so they are also real luxuries.

It shows that the world is interested in these diamonds. They will go to Sydney, Hongkong, New York and Australia for Perth tour before the deadline for bidding in October 21st.

He added: "Asia is particularly concerned about them, but after all, it is the global market, so Asia, the Middle East and the United States cannot afford to fall.

We have found that diamond investment has increased by more than 10% over the past twelve years, and we hope that this will continue. "
