Christie’s International, the world’s leading art business, has launched its new, free App designed specifically for users of the Apple iPad.

The new App takes users on a tour of Christie’s upcoming auctions and enables “at a glance” browsing of hundreds of luxury items and objects to be sold in the company’s salerooms worldwide.

Christie’s offers over 450 auctions annually in over 80 categories, including all areas of fine and decorative arts, jewelry, photographs, collectibles, wine, and more.

A large bronze sculpture of a woman’s back by Henri Matisse sold Wednesday for nearly 49 million dollars, setting a new record for the French impressionist.

Measuring 74.5 inches (189.2 cm), “Nu de dos” was the star of the auction at Christie’s in New York.

It went under the hammer just a day after rival Sotheby’s auctioned an Amedeo Modigliani painting for a record 69 million dollars.

“Nu de dos, 4 etat (Back IV),” had been estimated to sell for between 25 and 35 million dollars, before a bidding war sent the price spiraling to 48,802,500 dollars.

A rare, two-stone ring set a new record price per carat for a blue diamond at auction when it sold for $15.7 million to an Asian collector.

The ring features a 9.87 carat colorless triangular-shaped diamond paired with a triangular 10.95 carat “Fancy Vivid” blue diamond, the largest such blue diamond of this cut ever offered at auction.

The jewel had been bought in Rome in 1972 for $1 million, which is the equivalent of about $5 million today, Christie’s auction house said.

Artwork from the European branches of the collapsed US investment bank Lehman Brothers will go under the hammer in London next month in a two-million-pound auction, administrators said Sunday.

Works by Lucian Freud and Gary Hume will figure at the sale at Christie’s auction house on September 29, which comes two years after the bank’s demise.

“We think that there are many people around the world who would like to acquire some art with a Lehman connection,” said administrators PricewaterhouseCoopers.

On September 28th Christie’s in London will offer an incredible collection of vintage Louis Vuitton luggage during its Interiors: Style & Spirit sale.

Over 20 original pieces from the famed French luxury goods house dating from the late 19th century to the 1940s will go on the block.

Princess Diana’s family has sold an important Old Master painting by Peter Paul Rubens for nine million pounds at auction.

“A Commander Being Armed For Battle”, which is thought to depict the 16th-century Holy Roman Emperor, Charles V, was sold to an anonymous bidder at Christie’s auction house in London on Tuesday.

The painting, completed between 1612-1614, used to hang in Althorp which is the ancestral seat of Diana’s family and the late princess’s childhood home.
