In 2011, the market was shocked as it went up for auction by Christie’s and sold for $8.8 million.

5. Jennifer Lopez‘s 8.5-Carat Green Diamond

Value today: $10 million

In 2022, Ben Affleck proposed to J.Lo for the second time with a ring that is estimated to be worth $10 million from Harry Winston.

This ring features an 8.5 carat natural green diamond, which is extremely rare and apparently, considered a lucky color to the singer. In fact, Page Six reports that the color appears in “less than 0.1% of natural diamonds,” so therein lies the immense value.

4. Mariah Carey‘s 35-Carat Diamond

Value today: $10 million

Mariah Carey holds the fourth spot for the world’s most expensive engagement ring. Given to her by her ex-fiancée, James Packer, this ring cost a whopping $10 million, according to Brides. Set in solid platinum, this emerald-cut diamond ring is 35 carats and has two tapered baguette diamonds. A few years ago, it was revealed that Carey actually sold the ring for far less than Packer originally paid. A jeweler in L.A. paid about $2 million. This is unlike many of the other rings on this list appreciating in value, but this probably has to do with the fact that she sold it privately behind the scenes of the public.

Value today: $18 million

This exceptional 8 carat blue diamond ring was once the world’s most expensive engagement ring. In 2018, it was said to auction for $18 million, raising its estimated value from $13 million.
