De Grisogono
De Grisogono was a Swiss luxury jeweller. It was founded in Geneva, Switzerland, in 1993 by Lebanese-Italian black diamond specialist Fawaz Gruosi The Italian name "Grisogono" is derived from the Latin Chrysogonus which comes from the Greek "Chrysogonos χρῡσό-γονος", meaning "begotten of gold". Overview. In 2012, Gruosi had to give-up the majority in De Grisogono. The majority was taken-over by investors around the richest woman in Africa, the kleptocrat’s daughter Isabel dos Santos from Angola. Dos Santos had quietly routed millions of dollars through shell companies in Malta and the British Virgin Islands . In 2017, De Grisogono entered into a new partnership with former Leviev executives David and Lisa Klein. "Creation I," a necklace by de Grisogono, was sold for nearly Dh125 million, in 2017's Christie's sale. In 2017, the company set a new record at Christie's Magnificent Jewels sale in Geneva when it sold the world's biggest-ever emerald cut diamond offered at auction. The 163.41-carat D Flawless stone, which was cut from a 404 carat rough, was incorporated into a necklace designed by Fawaz Gruosi. It fetched 33.5 million Swiss francs, beating the previous record for  a D Flawless diamond by nearly five million Swiss francs. In 2010, Isabel dos Santos, set up a Victoria Holdings in Malta and funneled Angola's diamonds through De Grisogono out of the country.
