Rare coloured diamonds on display in Hong Kong
HONG KONG (AFP) - A mining giant is showcasing dozens of the world's rarest diamonds in Hong Kong, as it seeks to tap into the booming Chinese jewellery market.
The 75 pink, red and blue diamonds are being shown at a private exhibition by Anglo-Australian mining firm Rio Tinto, which unearthed a huge 12.76-carat pink diamond in Australia in February - the largest of the precious stones ever found in the country.
Less then 0.03 per cent of the world's diamonds are pink, which command up to 50 times the price of white diamonds.
Rio said the pink stones in its display could fetch up to US$1 million a carat when they go on sale later this year.
