World's Largest Diamond Ring to go to auction

A stunning110.03-carat yellow gem known as the Sun-Drop Diamond will go on sale next week in Geneva at Sothebys. The diamond was discovered in South Africa last year and is being sold by Cora International

The diamond is said to go for anywhere between $11m-$15. If it sells within its estimated price bracket, its worth-per-carat ($100,000-136,000) will actually be a bargain compared to the $201,000-per-carat sum paid for the smaller but more colorful vivid yellow diamond at Christie's in October (the price totaled $6.6 million for 32.77 carats).  (source)
