The Cora Sun-Drop Diamond

The Cora Sun-Drop Diamond is the largest known yellow pear-shaped diamond, weighing 110.3 carats.

It was sold for $10.9 million at Sotheby's auction in Geneva in 2011 and set a world record price for a yellow diamond. Cutting the diamond took six months. The Cora Sun Drop is cut in a brilliant pear shape. This is also known as a drop cut, hence the name.

Certified as "fancy vivid yellow" the Sun Drop is one of the largest diamonds of any color to have ever appeared at auction.

Yellow is the result of traces of nitrogen trapped within carbon molecules.
