On October 7, 2013, Sotheby's Hong Kong will auction a 118.28-carat D-color, flawless-clarity diamond at its Magnificent Jewels and Jadeite sale. The diamond, which is approximately the size of an egg (more pictures here), is the largest D-flawless diamond to ever appear at auction as well as the largest oval-shaped D-flawless or internally-flawless diamond ever graded by the Gemological Institute of America (GIA).
