The largest fancy vivid orange diamond ever sold at auction went for $35.5 million in Geneva, where a pink diamond estimated to be worth more than $60 million is also on the block.

The rare pear-shaped orange diamond sold Tuesday is 14.82-carats, meaning it went for an eye-popping $2.4 million per carat. That's a world record price per carat for any colored diamond sold at auction, Christie's said.

François Curiel, international head of Christie's jewelry department, said the orange diamond's record price puts it "amongst the greatest pinks and blues, which are traditionally the most appreciated colored diamonds."
