An investment group paid £50 million for Hirst's diamond skull
The annual Hiscox Art Market Research report also claimed modern art, produced from the late 19th century to the 1970s, has jumped in value by 44%.
The world's most expensive piece of contemporary art went for £50 million in August - a diamond-encrusted skull by Damien Hirst.

One of the artist's trademark medicine cabinets sold for £9.65 million earlier this year, which broke the European record for a work by a living artist.
In April, a Banksy painting - Space Girl and Bird - sold for £288,000, a record for the guerrilla artist.
And when Claude Monet's Waterloo Bridge went under the hammer, it fetched nearly £18 million.
"It seems that every few weeks another record-breaking price is being paid for a leading artist," added Mr Dupplin.
"The market for this art has never been so buoyant."
