Geneva · Geneva, since 1993
de Grisogono
Fawaz Gruosi opened this Geneva house in 1993, made black diamonds fashionable in 1996, and built big, saturated jewels around them: spirals of rings, gold spheres, crowds of coloured stones. Bankrupt in 2020 and bought by Dubai's Damac Group in 2022, it sells no jewellery online today; degrisogono.com shows only a 'Coming Soon' page.
