6. Beyonce – $5 Million
Jay-Z proposed to Beyonce with an 18-carat emerald-cut flawless centre diamond, which is set on a split shank band.
The platinum band contains micro-pavé diamonds and was designed by Lorraine Schwartz. Since it’s creation, it’s also inspired a number of other celebrity engagement rings, some of which are featured on our list!
Overall, the ring is subtle, classy and striking all at the same time.
