De Beers mined the Pink Star in South Africa in 1999, and it weighed 132.5 carats in the rough. The Pink Star is the world's largest diamond, with a Vivid Pink rating. The Beny Steinmetz Group dubbed Steinmetz Diamonds took a careful 20 months to cut the Pink Star due to its remarkable rarity. It was launched at a public ceremony in Monaco on May 29, 2003.
