Flawless 100-carat diamond sells for $22.1 million at NY auction –
An eye-popping, 100-carat diamond, the highlight of a magnificent jewels sale in New York on Tuesday, sold for $22.1 million, Sotheby’s auction house said. The perfect classic emerald-cut D color diamond, which is about the size of a walnut and was mined by De Beers in southern Africa, was purchased by an anonymous buyer via a telephone bid. It had a pre-sale estimate of $19 million to $25 million. Gary Schuler, the head of Sotheby’s jewelry department in New York, said the gem is the definition of perfection. The $22.1 million price, which includes the buyer’s premium, fell short of the $30.6 million world record price paid for a 118.28 carat white diamond in Hong Kong in 2013. Sotheby’s said only six perfect diamonds weighing more than 100 carats have been sold at auction in the last 25 years. [Reuters]

Japan maglev train breaks world speed record again –
A Japanese magnetic levitation train has broken its own world speed record, hitting 603km/h (374mph) in a test run near Mount Fuji. The train beat the 590km/h speed it had set last week in another test. Maglev trains use electrically charged magnets to lift and move carriages above the rail tracks. Central Japan Railway (JR Central), which owns the trains, wants to introduce the service between Tokyo and the central city of Nagoya by 2027. The 280km journey would take only about 40 minutes, less than half the current time. However, passengers will not get to experience the maglev’s record-breaking speeds because the company said its trains will operate at a maximum of 505km/h. In comparison, the fastest operating speed of a Japanese shinkansen, or “bullet train” is is 320km/h. (See Video of the day). [BBC]
