The Ponahalo Diamonds
In 2005, a rough diamond of 316.15 carats was discovered, the largest ever to emerge from the De
Beers Venetia mine. Following the tradition of naming very special diamonds, the name Ponahalo
was given by Jonathan Oppenheimer, Head of the Chairman’s Office De Beers Group. In Sotho,
the tribal language spoken by the Venda tribe in the area of South Africa where the gem was mined,
Ponahalo translates as “vision.”
The Steinmetz Diamond Group, one of the leading diamond manufacturing and trading groups in
the world, entrusted with the honor of cutting the 316.15 carat stone, expertly produced four
polished diamonds, leaving one in its rough form. It took eighteen months to shape the two largest
diamonds, weighing 102.11 and 70.87 carats, into rectangular-cut gems (estimate: on request).
A portion of the proceeds from the sale of the Ponahalo Diamonds will be donated to the Diamond
Empowerment Fund, co-founded by Russell Simmons. The Diamond Empowerment Fund is a
non-profit, international organization dedicated to empowerment in Africa through funding
education programs in African countries where diamonds are a natural resource.
