Married or not, engagement rings are weirdly easy to obsess over—hence why we just combed through every single celebrity proposal for a definitive ranking of the most expensive rocks of all time.More
Being queen of all things extra, we weren't exactly surprised to find out Mariah Carey takes the cake for the most expensive rock. James Packer popped the question in 2016 with a 35-carat diamond and platinum ring crafted by jewelry designer Wilfredo Rosado. The grand total? A whopping $10 million. Unfortunately, the couple never made it down the aisle—but it's rumored that Carey held on to the ring.
Elizabeth Taylor didn't play games when it came to jewelry (or husbands). In 1968, Richard Burton gave Taylor a 33.19-carat Asscher-cut diamond with an estimated worth of $8.8 million. It's no wonder she wore it for the rest of her life.
