507caratrough

September 24, 2009 was a lucky day in the South African Petra Diamond Cullinan mine when a 507.55 carat rough diamond (above) was found among the rubble. The huge stone–extremely rare and apparently of exceptional color and quality–is one of the top 20 largest high-quality rough diamonds ever found. Amazingly, three other very large rough diamonds were found in the same run at sizes of 168, 58.5 and 53.3 carats each.

I particularly love stories about Cullinan because I was lucky enough to visit the mine as part of a press trip several years ago. It’s amazing to see the vast amounts of land and resources used to unearth these relatively tiny gems.
