De Grisogono is a Swiss luxury jeweller founded in Geneva, Switzerland, in 1993 by Lebanese-Italian black diamond specialist Fawaz Gruosi.

[1][2] The Italian name Grisogono is derived from the Latin Chrysogonus which comes from the Greek Chrysogonos χρῡσό-γονος, meaning "begotten of gold".

[6][7] 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.

[8] In January 2019, Fawaz Gruosi supposedly left the company's board and his role as chief designer of De Grisogono.

[11][12] In August 2024, SODIAM sold its remaining shares in De Grisogono in a move to dismantle dos Santos' financial empire.
