SYDNEY-The annual sale of Rio Tinto’s rare pink-hued diamonds attracted unprecedented interest with at least two of the stones fetching record prices of over $2 million, the mining giant said Monday.

The 2013 Argyle Pink Diamonds Tender of 64 red, pink and blue stones drew a record number of bids over $1 million from established markets such as Japan and Australia as well as emerging markets China and India.
