Scarlett Johansson, $400,000
Engaged this May to SNL member Colin Jost, the “Black Widow” actress received an 11-carat pear-shaped champagne diamond with a deep brown band. Estimates for the cost of the ring currently range from $350,000- $400,000 and it is believed to be the work of James de Givenchy (the designer’s brand Taffin posted a similar ring on their Instagram @taffinjewelry in April which fueled the speculation).
