Fragment of Massive Diamond Sold for $17.5m

A piece of the world's second-largest diamond, found 2 years ago by Vancouver’s Lucara Diamond company, just sold for $17.5m.

The big rock in question is the 1,109-carat “Lesedi La Rona." They wanted $70m for it at the auction, but no one bid higher than $60m so they still have it.

The $17.5m diamond is a smaller piece that broke off of the "Lesedi."
