Bling!

Ray J may have good reason to have armed security follow him around, because he and his fiancee are dripping in tens of thousands of dollars in jewelry.

The singer hit up Richard Nektalov over at Leon Diamond in NYC for a 4 carat diamond and rose gold RJ pendant, with a $10k price tag attached. But that was just the beginning. Ray also left with a $40k rose gold Rollie and two charm pendents at $7,500 a pop.

Leon Diamond does well by Ray J ... it's where he bought the 8-carat engagement ring for Princess Love back in October.

Shia LaBeouf dropped strong hints, and now Mia Goth is confirming they've made it official ... by sporting a big ole diamond engagement ring in public.

Shia and British actress Mia were out running errands -- already looking like an old married couple -- in L.A. on Wednesday. The rock on her left ring finger was in clear view.

They've been together since 2012, and he recently referred to her as his "fiancée." But you know how Shia is -- until you see the ring, hard to know if it's REALLY a thing.

That shine coming out of Tyga's mouth is basically a brand new Chevy Impala -- that's how much dough he dropped to customize his new grill.

We found out T-Raw picked up his 18 karat diamond and rose gold grill from Johnny Dang & Co. earlier this week and spent $35k in the process.

Tyga is no stranger to mouthpieces -- this being his 5th grill commissioned by Johnny -- and if you remember he made a very similar purchase for Kylie Jenner last month around Valentine's day.

Luckily, he paid in full ... wouldn't want any repo companies waiting outside his dentist's office.

While Kanye's slashing his prices, the competition's going up -- WAY up, as in $4 million for a single pair of sneakers, and for some reason people are lining up to buy 'em.

The shoe is called "The Fire Monkey," but it's really just Dwyane Wade's Li-Ning Way of Wade 4 ... with several hundred carats of white diamonds and sapphires strategically added!

The ridiculous baller design is a collabo between Bicion, owned by "Growing Up Hip Hop" star Egypt Criss (Pepa's daughter) and Mache Customs.

A Bicion employee posted a brief peek at a pair that's only 60% completed. Our shoe sources say that was enough for 2 potential buyers -- from the Middle East and China -- who are flying to NYC next week to see the finished product.

San Francisco 49ers linebacker NaVorro Bowman is calling it quits ... on the single life ... preparing to tie the knot with his long time GF in a star studded April ceremony ... TMZ Sports has learned.

We got NaVorro leaving Avianne & Co. Jewelers in NYC and when we asked what kinda bling he was copping in there and he showed us ... by flashing a massive rock on a lovely lady's hand.

That lovely lady is Mikale Ferguson ... a celebrity stylist who Bowman's been with since high school and is marrying in a private garden ceremony at Caesars Palace in Las Vegas this spring.

The guest list is dripping with celebrities ... Vernon Davis, Glenn Dorsey, Dashon Goldson, and other NFL stars are expected to attend ... with more names likely to pop up.

Looks like another linebacker is creeping up on you, Russell.

10:14 AM PT -- We're told the ring is 10 carats and has a $175,000 price tag!!

There is no "Little Red Corvette," but 95 other pieces of Prince memorabilia are about to hit the auction block ... and they ain't going cheap.

The Nate D. Sanders auction in L.A. will feature jewelry, stage-worn costumes, instruments and other personal items obtained from his ex-wife, Mayte Garcia, and ex-manager, Owen Husney.

Prince's 2.2 karat diamond engagement ring -- given to Mayte in 1996 -- will go to the highest bidder starting at $100,000. Also featured are Prince's 1959 Gibson guitar for $60,000 and a 23 minute cassette tape from 1978 ... featuring 3 never released songs with a minimum bid of $20,000.

Russell Wilson finally put a ring on it ... A HUUUUUGE RING ... proposing to Ciara with a stone the size of a baby's fist.

The Seattle Seahawks QB popped the question during a private champagne dinner off the coast of Africa on an island in the Seychelles ... paving the way for him to finally bang the pop star.

As you know, the extremely religious couple took a vow of celibacy ... promising to keep their hands off each other until they get married.

Almost there, brother ... almost.

2 Chainz added a few more in an all out shopping spree at what sounds like his favorite spot in the world.

We got Tity Boi outside Avianne Jewelers in NYC, and you can tell from the video ... he was in the mood to do some serious shopping.

We spoke with owner Joe Avianne who told us Chainz left with a 25 karat black onyx stone ring outlined in diamonds, a 25 karat diamond tennis necklace, and an upgraded 30 karat diamond bracelet. Total damage -- $65,000.

We're guessing he was splurging to celebrate his new project with Lil Wayne, "ColleGrove."

As 2 Chainz would put it -- when he dies, bury him inside that jewelry store.

Von Miller is pimping out his million dollar smile ... with an insane $40,000 DIAMOND AND GOLD GRILL ... and TMZ Sports has the pics!

We spoke with grill guru Johnny Dang -- who's made crazy pieces for huge stars like Kylie Jenner, Fetty Wap and Bieber -- who says he just completed work on a sick custom piece for the Super Bowl MVP.

Miller's piece has everything from 18k gold to baguette and princess cut diamonds -- all VVS stones!

And that's not all ... we're told Von already has Johnny working on ANOTHER grill that'll be finished in a few weeks.

Gotta have a spare!!

Bubba Sparxxx has found his "Mrs. New Booty" and will be tying the knot with former Miss Iowa 2010 Katie Connors.

The couple started dating 2 years ago after meeting through mutual friends. They've rented out Andrew Jackson's Hermitage in Nashville for the big day ... May 21st.

"Save the dates" have been sent out to more than 400 friends and relatives. We're told the wedding will cost around $100,000.

As of now no one's set to perform, but you know booty, booty, booty, will be rockin' everywhere.

Reese Witherspoon's logo for her popular clothing and jewelry line is a dead ringer for a piece of jewelry designed several years before hers ... according to a new lawsuit.

Jordann Weingartner says she created in 2008, and got a copyright for a "distinctive six-pointed floral design" which she called Magnolia. In her lawsuit, Weingartner points out her jewelry is a hot-seller in stores and online ... and in multiple states including Florida, New York, Texas, and California.

Then along comes Reese in 2015, rolling out a magnolia design for her Draper James line, according to the docs. Weingartner says Reese's version is a total knockoff of hers and confuses the marketplace.

She's suing to get a cut of Reese's profits and to get her Draper James Magnolia yanked from stores ... like an annoying weed.

It's 59 degrees in Big D, but the forecast calls for ICE -- 215 CARATS worth -- around Dez Bryant's neck ... 'cause the Cowboys superstar ordered $200k worth of RIDICULOUS jewelry.

Bryant hit up Johnny's Custom Jewelry in Houston ... and commissioned a Cuban Link chain and bracelet ... as well as 5 "X" pendants for signature celebration move.

King Johnny -- the shop's owner -- tells TMZ Sports Dez wanted something unique ... so he designed and fabricated each piece, diamond by diamond ... which took 2 months.

The breakdown: 175 carats for bracelet & chain, and 40 carats for the pendants.

#ItsGoodToBeRich

Bella Hadid's rocking a ring on the traditional wedding ring finger ... but she and The Weeknd haven't gotten THAT traditional just yet.

When the couple rolled out of their London hotel Monday evening, photogs took notice of the golden piece Bella was sporting. Rumors immediately flew that Weeknd had popped the question, but hold your congratulations.

Bella's rep tells us there is NO engagement. They've only been together for about 10 months, so it would've been a pretty quick move on Weeknd's part.

Sometimes a ring is just a ring.

We now know how Kylie Jenner got her new grill ... it was a ridiculously expensive present from her boyfriend.

We found out Tyga dropped $15,000 at Johnny Dang & Co. for the 18k gold mouthpiece. All of the diamonds are invisibly set.

Turns out Johnny Dang is in high demand ... Big Sean, Travis Scott, Katy Perry and a bunch of other celebs have used his company to bling out their mouths.

It looks like the grill was a Valentine's Day present, though we can't be certain. Whatever the occasion, now she has a grill, a bunch of PUMAs and the right to rock Adidas.

Kanye West wants to make something perfectly clear ... people in massive debt don't sip champagne in super expensive jewelry stores while eyeing ridiculously pricey watches.

Check out the pics we got inside Jacob & Co. Monday night in NYC. The store is known for watches that will set you back the price of a small house.

We don't know what Kanye bought, but he's clearly making a point that he's still flush with cash and not $53 million in debt.

"Mob Wives" star Ramona Rizzo can't get $154,000 worth of jewelry back from the feds because her lawyer's an "incompetent" idiot ... according to the lawsuit she just filed.

Rizzo says federal agents were gunning for her bf Joseph Sclafani in 2011 when they raided their home and took 42 pieces of her jewelry. Rizzo insists all of her stuff was legally obtained and the feds have no reason to hold it.

She hired Tim Parlatore to help her get the goods back, but says he bungled the mission by turning in paperwork late, and failing to tell her when the feds requested documentation to prove the jewelry wasn't ill gotten.

Rizzo says she could have recovered "a significant portion" of the jewelry had she known.

She's suing Parlatore for the $154k value of her jewelry, plus damages for the "sentimental" loss. BTW ... Sclafani eventually got 15 years for dealing drugs.
