Some things are rare

For some reason, I wish there would be a discovery of a new really big diamond. Lesotho has produced some large ones this decade: http://www.gemdiamonds.com/b/d_famous.asp, including the Lesotho Promise in 2006. But the largest polished diamond cut from the Promise was only 75 carats. I want one that would be around 500 carats cut! The Incomparable, from 1988, is 407 and a half carats.

The Lesotho Promise (uncut, above) and the diamonds cut from it (below).
