Nickel price hits 4-year low as gloom offsets potential Indonesia cuts
Indonesia is now considering deep cuts to nickel mining quotas as it seeks to boost slumping prices of the metal.
A 6.16-carat blue diamond that was secretly passed down through European royalty over three centuries is going on sale for the first time in May.
The pear-shaped, dark grey-blue gem, known as The Farnese Blue, is believed to be one of the most important historical diamonds left in private hands, Sotheby’s said.
Expected to fetch between $3.7 and $5.3 million when it goes under the auction house’s hammer on May 15, in Geneva, the stone was found at India’s Golconda mines. It was then given to Elisabeth Farnese, daughter of the Duke of Parma, in 1715 to mark her marriage to King Philip V of Spain.

The royal couple descendants owned the Farnese Blue, as they married into other European families, travelling from Spain to France, Italy and Austria. During more than 300 years, nobody — except from close relatives and the family jewellers — knew of the gem’s existence.

“All this time, it was hidden away in a royal jewellery box,” Philipp Herzog von Wurttemberg, chairman of Sotheby’s Europe, said in the statement.
“With its incredible pedigree, the Farnese Blue ranks among the most important historic diamonds in the world,” he noted.
