London's Natural History Museum this month begins what it calls a "blockbuster exhibition" of some of the world's most spectacular white and colored diamonds.
Among the stones being featured:
The 203.04 ct. D Flawless De Beers Millennium Star, the world's largest flawless stone.

The Ocean Dream: the world's largest naturally occurring fancy deep–blue green diam
