Owners of the world’s largest cut emerald – a 57,500-carat natural wonder – will auction off the gem later this month, and the bidding starts at $1 million.

The gem – called Teodora, or gift of God, in Portuguese – was mined in Brazil and sold to an Indian buyer, but little is known of the stone’s origins.

Teodora weighs 11.5 kilograms. It is actually the fifth largest emerald ever found but the biggest that’s been cut with facets.

A 110-carat yellow jewel called the Sun Drop Diamond, thought the biggest of its kind in the world, sold for a record 10 million francs ($10.9 million) at auction in Geneva.

The gem was discovered in South Africa in 2010 and wowed visitors to London’s Natural History Museum where it was displayed earlier this year.

“It’s an absolute record for a yellow diamond,” Sotheby’s David Bennett told journalists after the sale. “It is a spectacular, unique stone.”

One of the world’s largest diamonds, a pear-shaped 110.3-carat yellow rock, will go under the hammer in Geneva in November expecting to fetch about $15 million.

The Sun-Drop diamond, discovered in South Africa last year, is billed by Sotheby’s as the “world’s largest known pear-shaped fancy vivid yellow diamond“.

“This stone has immense presence and is truly stunning. It is also one of the largest diamonds ever to have appeared at auction,” Sotheby’s Switzerland co-chairman David Bennett told a news conference in Hong Kong.

The fourth edition with the biennial Only Watch charity auction, held Friday in the Hotel Hermitage in Monaco, raised more than €4.5 million ($6 million).

Exclusive timepieces by famous and less famous watch manufacturers are being auctioned off for the benefit of researching Duchenne Muscular Dystrophy.

Complete sale results and a reminder of the models are available after the jump.

A 300-bottle collection of Chateau Lafite Rothschild has sold for almost $540,000 in Hong Kong, setting a world record price for a single wine lot auctioned this year.

The collection spanning 1981 to 2005 was knocked down for HK$4.2 million ($539,250) at Christie’s two-day Autumn wine sale.

The record price, below a HK$4.5 million pre-sale estimate, was “the highest value lot achieved at any wine auction worldwide this year,” Christie’s said.

Among the hundreds of lots on offer at Christie’s September wine auction in Hong Kong, there’s one in particular that will appeal to more than just wine lovers.

The winning bid for Lot No. 519 will receive a lunch date with Scarlett Johansson and six bottles of 100-year-old Moët et Chandon champagne packed in a special Louis Vuitton leather chest.

The lot is estimated to be worth 380,000 to 500,000 Hong Kong dollars (US$48,700 to $64,100). The proceeds of the sale will go to the Nature Conservancy in China.
