Diamonds cut from 316-carat Stone

On October 15th, Christie's will be auctioning (among other beauties), two stones cut from the 316.15-carat "Ponahalo" diamond. The smaller stone weighs in at 70.87-carats and the larger stone is an impressive 102.11-carats. It took a year-and-a-half to fashion the stones from the original rough cut diamond. 

A percentage of the sale of the stones will be donated to Russell Simmons' Diamond Empowerment Fund. The "DEF" helps promote and sustain educational programs in Africa where many of the world's diamonds come from. (via)
