According to a survey last year by The Knot, the average engagement ring now costs $5,680.  But when you’re a celebrity, nothing’s average.

A websiteput out a list of celebrity couples who have dropped a lot of coin on engagement rings, and how much they cost.  Here are the most expensive ones they listed…

1.  Mariah Carey and casino mogul James Packer…a 35-carat ring worth an estimated $10 million.  They got engaged in 2016, then split up less than a year later.  But Mariah got to keep the ring as part of a settlement deal.

2.  Kim Kardashian and Kanye West…a 15-carat ring worth $8 million.

3.  Katy Perry and Orlando Bloom…$5 million.  They got engaged back in February on Valentine’s Day.
