Bling!

Chris Harrison's finally cashing in on what happens after final rose ceremonies -- in theory, at least -- by helping the ladies put rings on their men.

"The Bachelor" and 'Bachelorette' host is launching his own signature line of wedding rings ... strictly for grooms-to-be. Chris hooked up with a company called Manly Bands, and the collab features wedding bands chosen and designed by Chris himself.

So, what's his style? We're told the Chris Harrison Collection is all about using unique materials. None of the usual boring bands for dudes. Instead, his 24 styles incorporate tantalum, meteorite and even dinosaur bone!!!

For your traditional types, he does have some gold and diamonds too. The rings cost from $650 to $3,500.

Chris says he's excited to "encourage men to look for exciting ways to express their love through their wedding ring."

Super sad news for ex-Arizona State football head coach Todd Graham ... his wife says 17 of his most prized championship rings were stolen in Arizona this week.

Penni Graham tells TMZ Sports ... she and the coach are in the process of moving to Hawaii from Scottsdale for his new head coaching gig -- and had given the rings to a close friend to help move the jewelry out to Honolulu.

But, Penni says someone broke into their friend's car Tuesday at around 1 PM a couple blocks from Arizona State's campus ... and stole everything.

Penni says the coach is heartbroken over the loss of the items ... and is pleading with the thieves to return them ASAP.

"So much went into earning those rings," Penni said, "especially his National Championship ring, as a coach in 1992. Seventeen rings from years of blood, sweat and tears. He is devastated."

Penni says they're working with the Tempe Police Department to try to get the rings back.

Todd had a ton of success as the Sun Devils' coach from 2012 through 2017 ... winning 10 games in 2013 and 2014 and earning 2 bowl victories.

He left the program after the 2017 season ... and just signed on in January to be the Univ. of Hawaii's new head man.

Just one month after the K.C. Chiefs players received their Super Bowl rings ... one of them is already up for auction, TMZ Sports has learned.

The ring was made for Mike Weber -- who was on the K.C. practice squad during the 2019 season when Patrick Mahomes led the team to a win over the 49ers in SB LIV.

The players received their rings in a special ceremony at Arrowhead Stadium on Sept. 1.

But now, the 23-year-old's ring has made its way over to Goldin Auctions, where it's up for grabs and the starting bid was $35,000. The current bid is already at $55,000 with 17 days to go!

Goldin tells us the ring is attracting a ton of interest and could easily hit the 6-figure mark.

As for the piece itself, it's a 10 karat gold ring featuring the Chiefs logo made with 60 diamonds ... and 2 Lombardi Trophies made with marquee-cut diamonds.

It includes 16 rubies to signify 10 AFC West division titles and 6 playoff appearances under head coach Andy Reid.

The perimeter of the ring top has 122 diamonds which represents 100 NFL seasons and the 22 playoff appearances in Chiefs’ franchise history.

Weber's name is on the side of the ring next to his jersey number, 45 -- and his signature is etched on the inside band.

Goldin says the ring comes with a custom Josten's ring box and a letter of authenticity from Mike Weber.

Weber was a Dallas Cowboys 7th-round draft pick in 2019 ... and spent most of the season on the practice squad there -- but joined the Chiefs' practice squad in January after the Cowboys' year ended.

Weber had re-signed with the Chiefs after the Super Bowl victory ... but was cut in the offseason after K.C. selected Clyde Edwards-Helaire in the 1st round of the 2020 draft. He's currently trying to get back into the league.

A crazy jewelry heist scene on "NCIS: New Orleans" got way too real for the actors involved ... when real cops showed up and pointed their guns at them ... and now they're suing.

The 2 actors involved in the scene, along with the jewelry store owner, have filed a lawsuit in L.A against CBS for allegedly misleading them into shooting a realistic "guerrilla-style" armed robbery in broad daylight ... without proper permits or giving cops and neighbors a heads up.

The 3 men claim they were approached by 'NCIS' producers in October 2017 about filming the robbery, and they agreed to do it under the assumption it was a "traditional television shoot" ... with permits, police present and standard safety protocols.

Instead, the men accuse CBS of failing to notify local authorities and surrounding businesses that the armed robbery scene -- set in the middle of a busy New Orleans shopping center -- was not real ... and you can guess what happened.

According to the suit ... the owner of the store next to the jewelry store understandably called 911 after seeing the actors jump out of an unmarked van in ski masks carrying realistic-looking assault rifles while yelling, "This is a robbery!"

This prompted cops to race to the scene and point their very real weapons at the actors ... who say they could have been killed by the officers with one false move.

The 3 men claim the ordeal was terrifying and traumatizing ... and they're still feeling the psychological effects. They're suing CBS for damages.

The network's filed docs to get the case tossed out of California court, arguing that it involves events that took place in Louisiana, so that's where the case should have been filed. The plaintiffs' lawyers, Caleb Mason and Alan Jackson, disagree ... saying the show is produced by CBS in L.A.

Antonio Brown's letting everyone know he's still got a "Whole Lotta Money" ... 'cause he just copped an INSANE iced out pendant and chain to celebrate his record label.

The 32-year-old superstar wide receiver started his music career -- and CAB label -- after the New England Patriots cut him last September due to multiple off-the-field incidents.

AB has released songs, mixtapes and music videos ... but wanted to take it a step further, so he hit up celeb jeweler Leo Frost and commissioned the bling.

We're told the CAB Records pendant is decked out in 18k gold and is filled with 32 carats of VVS diamonds.

The Cuban link handset chain is also 18k yellow gold ... and has 65 carats of VS1 diamonds.

Overall, the piece has a whopping 97 carats of diamonds.

It's unclear how much AB dropped on the chain and pendant ... but Frost's work ain't cheap -- and neither is that many diamonds.

The jeweler has hooked up some of the NFL's biggest stars in the past ... with ballers like Saquon Barkley and Joe Burrow going to see Frost.

Despite the music, AB -- who is currently in the middle of an 8-game suspension -- is still training for an NFL comeback.

Pittsburgh Steelers star Bud Dupree just copped a ridiculously ICED OUT watch encrusted with 30 carats of diamonds ... and it's worth 80 grand!!

TMZ Sports has learned the Steelers linebacker treated himself with some new bling to celebrate the 2020 NFL season .. hitting up jeweler Moe Diamond in Pittsburgh.

Moe -- whose hooked up NFL beasts like Aaron Donald in the past -- delivered the Audemars Piguet watch ... loaded with approximately 30 carats of VS-VVS diamonds, to Dupree.

You can (literally) see the sparkle in BD's eyes.

The AP -- which we're told was appraised at $80,000 -- also has a custom gold bezel.

It's a crazy expensive watch -- unless you're making $16 million this season -- like Bud ... who's one of the highest-paid defensive players in the league this year.

And, he's definitely earning his money ... 'cause he's already racked up 2.5 sacks for the 3-0 Pittsburgh Steelers.

The long-nailed woman who allegedly stole Kyle Richards' ring has pretty solid proof she's been wrongly accused, and wants an "I'm sorry" from the 'Real Housewives of Beverly Hills' star.

Diana French is a retired pharmacy clerk from L.A. who went viral -- well, her hands did anyway -- after, for some strange reason, actress Diane Keaton shared a photo of her hands ... calling Diana's black nails "too much" and claiming she's a fortune teller.

The nails are up for debate, but Diana says the fortune teller thing is untrue.

Anyway, Richards saw Keaton's post, and believed she recognized one of the rings Diana's wearing as her mom's stolen ring ... which got swiped back in December 2017 when Kyle and her husband's home was hit by burglars.

After Diana went viral for all the wrong reasons ... her granddaughter took to TikTok to clear her name.

She also defended herself by going on "Inside Edition" with even more proof the ring belongs to her ... including old photos of her wearing it, and the original appraisal from FORTY years ago.

Kyle had gone public with her search for the stolen ring, but to be fair, she never accused French of theft. She thought French might have purchased the ring from a pawn shop, and was going to offer to buy it back from her.

This is the greatest marriage proposal fail ever ... when a bride gets so excited she hits the gas of her powerboat ... sending her would-be groom flying in the air.

Check out the aspiring groom walking on the back of a boat ... lasering in on the unsuspecting bride-to-be who is on another boat ... separated only by a foot or so.

He pulls out a ring and she's super shocked, exclaiming, "Oh my God!!!"

Now the buzzkill. He leans in for a kiss and she accidentally hits the gas pedal.  Her legs kick up in the air, hitting him as he falls off the boat in hilarious fashion.

We're guessing since she was obliging with the kiss, she said yes.

Demi Lovato won't be walking down the aisle with Max Ehrich ... TMZ has confirmed the singer and actor called off their engagement.

Demi and her former fiancé have officially called it quits, splitting just over 2 months after he popped the question on the beach in Malibu.

A source close to the singer tells TMZ ... "It was a tough decision, but Demi and Max have decided to go their separate ways to focus on their respective careers."

The source adds, "They have respect and love for one another and will always cherish the time they spent together."

Demi and the "Young And The Restless" actor started dating back in March, just as quarantine was beginning, and their relationship moved quickly. He proposed in July and slid a huge rock on her finger.

At the time of their engagement, Demi said she knew she loved Max the moment she met him and was "ecstatic to start a family and life" with him.

The timing of the split is interesting ... coming only 10 days after Max allegedly got thirsty on social media over Selena Gomez, Miley Cyrus and Ariana Grande. Demi had defended him, though, claiming screenshots of his alleged messages were faked.

Regardless, they're no longer getting married. People first reported their split.

PHEWWWWWWWWWWWW!!!

Indianapolis Colts star linebacker Darius Leonard damn-near LOST his wedding ring gifting a pair of his game-used gloves to fans ... but, thankfully, TMZ Sports has learned he got it back!

Here's the deal ... after the Colts destroyed the Vikings on Sunday at Lucas Oil Stadium -- Leonard gave away his mitts to some young fans who were in attendance.

The problem? As Leonard was taking off his gloves ... his wedding ring got caught in them -- and then he unknowingly handed it over to the kids!!

A family member of the glove recipients posted about the whole thing on social media Monday ... and when Leonard caught wind of it all -- he wrote back, "I need that."

Ya think!?!?

Happy ending for Darius though ... we're told the fans are good friends with a Colts staffer -- and were able to return the ring no problem.

How'd Kansas City Chiefs rookie Clyde Edwards-Helaire celebrate his huge NFL debut??

DIAMOND PENDANTS, BABY!!!

TMZ Sports has learned Patrick Mahomes' new star teammate just copped some ice after his first-ever monster game in the pros ... and the jewelry is INSANE!!

We're told the running back -- who rushed for 138 yards and a TD in the Chiefs' opening game last week -- hit up Leo Frost to make FIVE pieces ... and the celeb jeweler didn't disappoint.

The bling features the word "Glyde" -- a play on Clyde's "The Glyde" nickname -- as well as his former LSU jersey #22.

We're told each pendant is decked out in 18 carats of VVS diamonds ... plus Clyde's drip includes a bracelet and a Cuban link chain that also have "Glyde" on the locking clasps.

Unclear how much Clyde paid for the pieces ... but we're told the RB is spreading the pendants out to some of his closest family members and friends.

Atlanta Falcons star Calvin Ridley will be reppin' his new baby daughter everywhere he goes ... courtesy of a brand new diamond chain!!

TMZ Sports has learned ... the 25-year-old former Alabama receiver wanted to do something WAY better than a picture in the wallet to show off his daughter, so he hit up Al the Jeweler of Labelle Jewelry in NJ to come up with the special piece.

The final product is a massive charm featuring Cree Michelle's name and birthday -- 06-27-2020 -- sitting on an NFL logo.

We're told the piece is made of more than 70 carats of VS clarity diamonds between the pendant and chain it sits on ... in other words, high-quality stuff!!

Ridley isn't the only one getting treats ... check out the Louis Vuitton blanket his baby girl was laying on when he introduced her on IG!!

Ridley -- who is still on his rookie contract -- has made about $9 million in his 3 years in the league so far ... but expect that number to rise if he continues to ball out!!

Janelle Pierzina didn't last long on this season of 'Big Brother,' but boy did she cash in -- selling a necklace she wore on the show for a small fortune, before putting that dough to good use.

The "Big Brother All-Stars" contestant wore a gold-plated "Janelle" necklace this season, and while she was the third houseguest voted out ... that necklace is now a sweet silver lining.

Janelle decided to sell it on eBay ... and it went for a whopping $18,300!!!

But, get this, Janelle -- who made the top 3 on "Big Brother 7 All-Stars" in 2006 -- decided to donate the entire proceeds to Give Kids The World Village ... an 84-acre village in Central Florida that offers weeklong vacations to children with critical illnesses and their families.

The trips come at zero cost to the families, thanks to donations like Janelle's.

Here's one more thing to add to your "This Can't Be Happening 2020" f***-it list -- folks are sliding into DMs for some lovin' ... but not for booty calls, more so marry-me-buys.

It's true ... with pretty much all of us being quarantined and hesitant and/or prohibited from going into shops these days, love birds are starting to flock to the digital space to find their engagement rings -- especially on IG and TikTok, which is proving to be oh so fruitful.

Take The Clear Cut, for example -- a huge company that's shifted to social media to facilitate sales, and we gotta say ... they're kinda genius, 'cause the numbers are jumping.

TCC's co-founder, Kyle Simon, tells TMZ that they've seen a whopping 330% increase in revenue over the past few months ... ever since they started posting their engagement ring selection on the 'Gram and TikTok, which we're told they get hit up about directly now.

Yes ... that means customers are literally sliding into their DMs to ask about specific items they've seen and wanna buy. From there, Simon and co. take them to the next phase.

Clear Cut has a huge product line, but we're told engagement rings specifically are flying off their digital shelves faster than they can stock 'em ... and that the most expensive ones they've agreed to sell via social media ran about $70k. On average, they're flipping $20k rocks.

Hey, nobody said getting married was cheap! Anyway, the point is ... CCJ is now doing 80% of their business on Instagram, and siphoning traffic from their TikTok account too. It's wild.

As for why this is happening -- especially the pricier splurges we're told they're experiencing -- Simon says people's budgets have changed ... no more forking out an arm and a leg for venues, honeymoons or anything else uber expensive (at least not for now) ... so more people are spending that extra dough on the ring they wanna put on someone's finger.

Win-win!!!

THE DISRESPECT IS REAL!!

Cam Newton says Miami Dolphins players tried to snatch the chain off his neck after his Patriots won on Sunday ... and it's all on video.

The New England QB was wrapping up a 21-10 victory at Gillette Stadium in Foxborough when cameras showed several Dolphins players jawing at Cam.

At one point, a hand reaches into the camera frame and tugs violently at Cam's neck -- it looks like the chain was snapped, but Cam managed to save it.

Eventually, Cam's teammates stepped in and separated the players.

The QB changed into his snazzy yellow outfit and talked about the incident after the game.

"I still got my chain," Cam said with a smile ... "I got two of 'em. So you could see. It was disrespect, they was reaching for my chain, though."

He continued, "I think that kind of got under my skin. But yeah, through it all, man ... listen -- I do not want nothing to be taken away from a great team game that we did have. And I don't want to be selfish to kind of focus or dwell on that."

"I think for us as a team, or me personally -- a lot of tempers can flare. And I was just teasing with Coach, just letting him know that the College Park almost came out in me."

Later on, Cam posted on social media about the incident -- saying, "Tried to snatch my chain and the game ... too bad I got both!"

Two Dolphins players responded.

Miami defensive end Shaq Lawson wrote, "We don’t won’t that weak ass chain."

And defensive tackle Raekwon Davis added, "Man ain’t nobody want your fake ass chains shit was weak anyway."

WHAT IS GOING ON HERE??!

Soccer superstar Jerome Boateng has a LOT to celebrate -- he just won the Champions League AND turned 32 ... so naturally, some diamonds are in order!!!

TMZ Sports has learned ... the Bayern Munich defender wanted to commemorate his recent accomplishments with some one-of-a-kind ice, so he hit up his go-to-guy, Gabriel The Jeweler to make him a personal gift.

The finished product is incredible -- a massive link chain made of 110-carat VVS diamonds and white gold ... and we're told it's valued at a solid $200k (though unclear exactly how much Boateng paid for it).

The chain has smaller diamonds on the outside and larger stones in the middle to really make the thing pop.

Boateng celebrated his special day on Thursday ... just a little over a week after beating Paris Saint-Germain in the UEFA Champions League Final.

Of course, Boateng came to Gabriel for a $350k jewelry spree of watches and chains last year ... and we're sure this won't be the last, either.
