Bling!

The Houston Astros are getting some serious bling long before their rings arrive -- 'cause Paul Wall says he's hookin' up EVERY PLAYER with a custom gold grill.

The craziest part -- the rapper and his business partner Johnny Dang are trying to get it done BEFORE the World Series parade on Friday!!

We got Wall and Dang after their hometown 'Stros clinched the Series ... and they told TMZ Sports they ain't sparing any expense when it comes to H-Town's MLB champs.

Not only is the entire 40-man roster (and their hot WAGs) getting their own personalized teeth swag -- but each one is coming in 18 karat gold!!

Wall says the players might have to break out the plastic if they want a full mouth of diamonds ... but beyond that, everything's fair game.

Astros third baseman Alex Bregman approves.

Cardi B's walking around with a fortune on her left hand ... because Offset definitely didn't skimp when he put a ring on it.

The Migos rapper dropped $550k on Cardi's engagement ring, which took a month and a half to make ... according to the owner of NYC's Pristine Jewelers. It came together just in time for Offset's live onstage proposal, but means he really must have been sweating during their brief breakup.

Cardi's shiny 8-carat stone's surrounded by 2 half-carat pear diamonds and 2 carats worth of pink and white stones. The ring's totally custom made in the raindrop shape Offset wanted.

It also worked out perfectly -- we're told the ring was finished by the day of the Philly Powerhouse concert and he picked it up just hours before he proposed.

As we reported ... Offset could get a big chunk of his ring money back -- he and Cardi B are wanted for a TV wedding special that could land the couple one million bucks.

Kim Kardashian gave the appearance she's going back on her word to swear off flashy jewelry in public, but it was nothing but a trick ... TMZ has learned.

Kim was wearing a couple of diamond rings over the weekend as part of her Cher costume at George Clooney's and Rande Gerber's Casamigos party. Seemed odd because she promised to tone down the bling after the Paris robbery.

Thing is ... those rings weren't even close to the real McCoy. Our Kardashian sources tell us Kim was, appropriately for Halloween, wearing nothing but costume jewelry.

Word. Kept.

DJ Khaled is hooking up his famous son, Asahd, with 2 things for his 1st birthday -- a sick diamond-studded watch, and a ton of patience ... 'cause he can't even wear the watch yet.

Khaled's wife, Nicole Tuck, commissioned Haute Living -- which also threw the birthday bash -- to make a VERY nice watch for Asahd. The piece is laced with more than 600 diamonds which weigh in at 11.65 carats ... all for just over $100k.

We're told the watch is a Franck Muller model in rose gold, with Asahd's name and birth date engraved on the back. It's also adult sized, and seeing as how Asahd just turned 1 ... he probably won't be ballin' out anytime soon. Good to know it's waiting on deck though.

You da best, Mom & Dad!

Gucci Mane's diamond heart has just 1 key ... and luckily his new wife Keyshia Ka'oir is holding it.

The newlyweds got a pretty baller gift from Gucci's best friend -- Pierre "Pee" Thomas, CEO of Quality Control Music -- two 28-carat diamond necklaces, and each has an additional 15-carat diamond pendant attached.

Gucci got the heart pendant, and wifey has the key. The jewelry -- made by Wafi Lalani at Jewelry Unlimited in ATL -- was delivered in an awesome case that plays Gucci's song "Curve."

Now, that's how ya lock it down.

Chanel West Coast just one-upped Future in the mask game ... wearing one that's bigger and more bedazzled than the one he wore on the BET Awards red carpet.

Chanel dropped a few thousand bucks to rent the blinged-out ensemble in her "New Bae" video featuring Nicki Minaj's ex, Safaree Samuels. It's made by Marianna Harutunian, the same designer who created the custom masks Future and his daughter wore to the BET Awards in June.

The mask CWC wore retails for $3,000 since it's made with over 8,000 Swarovski crystals. She also wore a Harutunian-designed crown and matching bodysuit in the vid which retail for $3,800 and $3,500, respectively.

Chanel's shine would've cost her more than $10k, but sadly she didn't get to keep the duds since they were on loan.

Not exactly a bad thing ... she looks better with the mask off.

Offset made a jewelry run in NYC, with his gf Cardi B apparently in tow, but made it clear he wasn't icing her up ... 'cause he doesn't need to anymore.

The Migos rapper came out of the jeweler Wednesday afternoon loaded down with a new pendant and 3 flashy watches worth at least one exotic sports car. When we asked if any of the new gear was for Cardi ... Offset had the perfect response -- especially because we're pretty sure she was in earshot, waiting in their ride.

Well, we know he's bought her bling before ... but that was B.B.Y. -- before "Bodak Yellow" blew up.

Fergie's fully owning the single life down in Brazil ... in a micro-mini outfit and no Josh Duhamel wedding ring.

Ferg touched down in Rio Wednesday, and tried to draw eyes away from her leggy leopard-print outfit and knee-high boots by holding up her left hand. She flaunted 4 rings spelling out F-E-R-G. Mind you, this was the day before she and Josh announced their separation.

As we reported, they split earlier this year, and say they took time to adjust before announcing it.

Fergie's down there to perform in the Rock in Rio music festival. Josh is back home with their son, Axl, and was seen Wednesday ... still wearing his wedding band.

Afrojack didn't just ice up his own neck for his birthday, he made sure his whole crew was shining ... even though it cost him SIX figures! Best. Friend. Ever.

The Dutch DJ ordered 5 chains with custom Afrojack logo pendants made with white gold and diamonds. He bought one for himself, but the other 4 went to his closest friends. A source close to Afrojack tells us it was a thank-you for supporting him during his 10 years in the biz.

We're told each of the 5 pieces cost $20k -- and Afrojack hit up celeb jeweler Ben Baller of IF & Co. because he was impressed by Lil Uzi Vert's new chain. The goodies were delivered last weekend to his 30th bday bash in Holland.

Talk about a happy customer ... we're told Afrojack ordered 5 more for other members of his entourage.

We're saying he's spending like there's "No Tomorrow" -- his new track -- but he's got stacks for days.

L.A. Lakers rising star Larry Nance Jr. is officially off the market ... 'cause the NBA baller just proposed to his college sweetheart with a MASSIVE diamond ring!!

The 24-year-old and his longtime girlfriend, Hailey Pince -- a fellow U. of Wyoming alum -- announced the big news on social media Tuesday by showing off the huge rock.

LNJ and the aspiring model have been dating for over 3 years ... and he explained his decision to pop the question by channeling his inner Beyonce, saying "I liked it, so I put a ring on it."

Nance can reportedly make up to $7 million over the next 3 years ... so yeah, dude can afford to splurge on his girl.

If you didn't peg Gucci Mane as a cat guy, you're not alone, but he is -- as long as they're panthers, that happen to be blanketed in diamonds!

Gucci just scored this sick chain which he actually designed himself. The double panther head piece has a total diamond weight of 165 carats. The cats alone have 1,800 stones, while the necklace has 2,800.

Diamond Club Miami did the labor, and owner Gary Tinhasov tells us Gucci dropped about $500k for his customized chain. Sources connected to the rapper tell us the panthers represent 3 things: courage, valor and power.

We'd like to add FILTHY RICH and ICY. As Gucci says ... "Brrrr!!!"

Gucci Mane's wedding invite glistens like one of his old grills, and it also put a $50,000 dent in his wedding budget!

Guwop opted for his real name, Radric Davis, on the super fancy invitation he and Keyshia Ka’oir sent out for their million dollar wedding this fall. It's being filmed for BET, and will clearly be an over-the-top event.

Each invite is a mirror-inspired booklet adorned with Swarovski crystals inside ... each for a mere $1k.

We're told 100 people are on the guest list with plus-ones, but only half got the fancy document. Most of them were Gucci's celeb pals and collabs like Drake, Rihanna, The Weeknd, Selena Gomez, Pharrell, Diddy, Rick Ross, Monica, Trina, Migos and Solange.

If you're wondering ... it's their international guests who aren't getting the invitation, due to shipping costs. Of course, seems late for cutting corners -- the wedding's going down at the Miami Four Seasons, after all.

Amber Rose and 21 Savage are getting seriously serious -- there's a $50,000 ring on his finger to prove it.

We're told the fresh ice the rapper had on his right ring finger at the VMAs is an 18-karat gold promise eternity ring ... and it was a surprise gift from Amber. It's made up of 1,100 stones -- white diamonds and red rubies spelling out "Loyalty 21."

IF & Co. jeweler designed the promise ring for Rose and Ben Baller hand-delivered it in time for the awards show.

On top of the $50k gift, Amber posted she was going to "pounce on" 21 Savage as soon as they got home from the VMAs ... proving he was also one of the night's biggest winners.

Jeremy Meeks is the undisputed rebound champ ... IF the massive rock on his heiress GF's hand is indeed proof he's locked her down.

The felon-turned-model and Chloe Green -- whose father has a $5 BILLION empire -- hit up Nobu Tuesday in Malibu tamely holding hands, and perhaps ... tried to hide her new bling

But Jeremy and Chloe posted a video of themselves all over each other, and Chloe's ring -- which looks awful engagement-y -- was blindingly obvious. It may appear to be on her right hand, but remember it's a selfie so the image is flipped.

The fast lane seems to suit Jeremy. He filed for separation from his wife just last month.

Big Sean is a bo$$ with shiny chains to flo$$ ... and the boss life ain't cheap.

The rapper dropped $180k for two 50-carat diamond chains. We're told it's the handy work of celebrity jeweler Elliot Eliantte, who got to work fast after Big Sean hit 'em up for the VIP treatment.

The chains are sick ... instead of going with a traditional pendant, Big Sean opted for a "Don Life" ring ... one in various colors and the other black and gold.

We're told Elliot needed 2 months to get the job done. He delivered it to Sean at the Billboard 100 Music Festival at Jones Beach, NY.

Admire at your own risk ... in case you decide to burn your kid's college fund.

The engagement's off ... but if you think Evelyn Lozada is giving back that 14.5 carat diamond engagement ring she got from Carl Crawford you're out of your mind.

The ex-MLB superstar -- who once signed a $142 MILLION contract -- proposed to the "Basketball Wives" star with the $1.4 million ring back in 2013. Evelyn obviously said, "Yes."

The two were set to get married 3 weeks ago -- but Evelyn pulled the plug after getting suspicious about Carl's fidelity.

Legally, Lozada is obligated to give the ring back -- since an engagement ring is considered a conditional gift in California, the condition being she has to get married.

But sources close to Lozada tell us ... Crawford ain't getting it back, period.

We're told she's planning on keeping the ring in a safe and passing it on to her kids one day. And at this point, she's not expecting Carl to put up a fight.

Talk about a fabulous parting gift.
