In the US, the average spent on an engagement ring is $6,351 but how do these figures compare with our favorite celebrities? The answer: they don't. Celebrity engagement rings are unsurprisingly getting bigger and bigger (um, have you seen tennis player Caroline Wozniacki's massive bauble?). As the diamonds increase in size, obviously the price tag appreciates handsomely. Well, we've compiled a list of some of the most expensive celebrity engagement rings to date courtesy of research from online jewelry retailer Jewellerybox, so you can keep up.

With prices ranging from $1,000,000 to the grand prize of over $38 million thanks to the power of inflation, these sparkling stars have accumulated quite the covetable jewelry collection—and we have the pics to prove it.

So, whose big-time bling ended up on top? And whose name popped up three times? Without further ado, we present 21 of the most expensive celeb gems—from least pricey (albeit still mind-bogglingly costly) to most.

18. Hilary Duff

Retired NHL player Mike Comrie, ex-husband of former Disney star Hilary Duff, reportedly spent a million bucks for a 14-carat, princess-cut jewel in 2010.

Model and Brides cover star Kate Upton first debuted her round engagement ring from Justin Verlander at the 2016 Met ball, and we've been jealous ever since...especially considering US Weekly predicts that the bauble is complete with an 8-carat diamond and likely falls within the $1.5 million range.

16. Jennifer Lopez

Prepare to see this ring finger pop up a few times on this list (three to be exact). While J. Lo had been married twice before at this point, in 2002 her high-profile relationship—the original Bennifer, if you will—got the star her first major engagement bling. At the time this pale pink 6.1-carat ring ran Ben Affleck $1,200,000 (now worth over $1,700,000). The two never made it down the aisle.

15. Katie Holmes

When the actress said "yes" to Tom Cruise in 2005 she got this $1,500,000. Even though TomKat didn't last, the engagement ring is nearly $2 million now.

14. Paris Hilton

The hotel heiress announced her engagement to Chris Zylka in January 2018, and her fiancé popped the question with a massive 20-carat bauble (which she proceeded to lose in a club...), worth an estimated $2 million. That's hot. This also isn't her first rodeo—Hilton was previously engaged to a fellow of the same name, Paris Latsis, in 2005. The former proposed with a 24-carat jewel, which Hilton auctioned off to benefit Hurricane Katrina victims.

13. Serena Williams

We can't forget how lavish Serena's 2016 wedding to Reddit co-founder Alexis Ohanian was. So, of course, her ring had to be just as luxe as the nuptials. Just how luxe? $3 million!

12. Ciara

Veering even deeper into pricey celebrity engagement rings, Ciara's left ring finger totes a massive diamond sparkler from Russell Wilson, believed to be worth between $2 million and $2.5 million. The "1, 2 Step" singer sported a similarly gigantic rock during her prior engagement to rapper Future, but the 15-carat gem was only thought to be worth a mere $500,000.

11. Blake Lively

Not only are Blake Lively and Ryan Reynolds the ultimate #couplegoals, but the blonde beauty is also total #engagementringgoals. Weighing in at 7 carats and an estimated $2.5 million, the gem features a light pink, oval diamond set in pavé diamonds and rose gold.

10. Alexa Dell

The year was 2017 and Dell Technologies heiress (her father, Michael Dell, is the chairman and CEO of the company), Alexa Dell got engaged to her beau Harrison Refoua. She shocked everyone when she showed off this enormous emerald cut ring surrounded by smaller diamonds set upon a thin diamond-encrusted band. Then, she shocked everyone again when they called off their engagement. The $3,000,000 ring is worth slightly more now.

9. Catherine Zeta-Jones

Considering Catherine Zeta-Jones and Michael Douglas's nuptials secured a spot on our roundup of the most expensive weddings to date, it's only natural that the actress's vintage Fred Leighton ring would earn a similar accolade at a cool $1 million. Douglas opted for a 10-carat, side-set, marquise diamond bauble for his now-wife of almost two decades.

8. Melania Trump

Donald Trump gifted his bride-to-be and one-day FLOTUS, a ring worth $3 million in 2004, which is now estimated to be worth over $4 million.

7. Kim Kardashian

This list would be nothing without Kimmie's rock from Kanye, which clocked in at around a cool $4 million when he presented it to her at his stadium proposal in October 2013. Unfortunately, though, the 15-carat sparkler was among the jewelry stolen during Kim's infamous Paris robbery in 2016.

6. Jennifer Lopez (Again)

JLo's ice is so nice, she made the list twice. Alex Rodriguez popped the question to the singer, and he really had to step it up to outshine her previous engagement rings—and wow, did he deliver. The baseball star proposed with a reported 15-20 carat emerald cut stunner set on a platinum band that was estimated at $5 million. It's getting harder and harder not to be fooled by the rocks she's got...

5. Jennifer Lopez (Yes, Again)

Before J. Lo and A. Rod, there was J. Lo and Marc Anthony. Although the couple ended their marriage in 2014, 10 years previously Anthony had proposed with a rare blue 8.5-carat diamond ring, worth $4 million has already surpassed A-Rod's ring due to inflation and is valued at $5,513,774 today.

4. Beyoncé

It should come as no surprise that Queen Bey herself totes one of the world's highest-valued diamonds. Weighing in at 24 carats, Jay reportedly paid around $5 million (now worth $6,047,013) for Bey's flashy emerald-cut ring back in 2008.

3. Paris Hilton (Again)

Remember when Paris got engaged to Greek shipping heir Paris Latsis (#Paris2x)? We barely do either, but we do remember her sporting the bauble around on the red carpet circa 2005, estimated to be worth $4,700,000 at the time. Today, the ring has seen a significant increase in value at $6,266,378. I guess the question on all our minds is, did she give it back?

2. Anna Kournikova

The Russian tennis star's relationship Latin music artist Enrique Iglesias since the early '00s has been one of the most lowkey celebrity relationships to date. That is with the exception of her $5,400,000 engagement ring that made headlines in 2004. Now, worth a whopping $7,443,596, the giant yellow stunner was spotted on Kournikova even during her tennis matches. (Pssst! It's rumored she got two rings from Iglesias. Prior to this, she sported an equally giant pink pear-shaped ring.)

Clocking in as the most expensive celebrity engagement ring, Mimi's 35-carat bling from ex-fiancé James Packer reportedly cost a cool $10 million. And the "Obsessed" singer seemed to be a bit, well, obsessed with the jewel. She continued to wear the ring over a year post-breakup, and didn't part ways with the bauble until May 2018, selling it to a Los Angeles jeweler for $2.1 million.
