Mining giant Rio Tinto said it has unearthed a "remarkable" 12.76 carat pink diamond in Australia, the largest of the rare and precious stones ever found in the resources-rich nation. Named the Argyle Pink Jubilee, the huge rough stone was found at Rio's pink diamond operations in the Kimberley region of western Australia and would take 10 days to cut and polish, the miner said on Wednesday.
