Bling!

Sofia Richie is going for the gold after splitting with Justin Bieber ... ordering up 3 custom grillz.

New York jeweler Richie Nektalov, aka Richie Rich, tells us he stopped by Sofia's pad while he was in L.A. last week to personally fit her for the grillz.

We're told Sofia went all 14 carat gold and high quality diamonds ... which cost between $2,500 and $3,000 each.

Best way to get over a breakup? Spend about $9k to brighten up your smile.

French Montana threw down stacks to bling out Iggy Azalea's digits ... TMZ has learned.

Sources close to French tell us the rapper dropped about $100k on the 7 rings he gifted her earlier this week. The rings were crafted by celeb jeweler Iceman Nick, who's also done some expensive bedazzling for a bunch of other rappers.

The purchase did the trick. Iggy gave French a shout-out on Instagram, after weeks of denying they've hooked up.

Kanye West doesn't just rant on Twitter, he also makes deals ... as a guy in Toronto found out after 'Ye shocked him by making a purchase.

Maison Raksha, the jeweler behind Toronto Grillz, started making 14k gold “I Feel Like Pablo” necklaces right after Kanye dropped his album.

Raksha tells us he shot for the moon by tweeting Kanye to say he made a chain for Kim, and it could be hers for $500. He says he was surprised when Kanye's stylist responded, and said 'Ye would love it, but wanted the necklace to simply read "Pablo."

Raksha delivered a month ago, and Kanye wore the chain for his Harper's Bazaar cover shoot, and he's worn it on tour too.

Kylie Jenner's now square in the middle of Tyga's financial nightmare, and it means she might have to sing like a canary about the expensive gifts he's bought her ... TMZ has learned.

According to docs obtained by TMZ ... Kylie's agreed to answer questions about her bf's finances. As we've reported ... celeb jeweler, Jason of Beverly Hills, is going after him for a $200k debt -- and this is the next step.

Since Tyga has a history of buying Kylie big ticket items, like a brand new Maybach, we're told the jeweler's law firm -- Abir, Cohen, Treyzon, and Salo -- wants to know everything he's gifted her.

The lawyers are set to privately meet with Kylie and Tyga within the next couple weeks. If they no-show, Jason's legal team says they'll push to have them arrested.

These are the same guys who got the warrant for Tyga's arrest last month, which forced him to pay up on a previous debt. They clearly mean business, and now Kylie's on notice too.

Iggy Azalea is warming up to French Montana ... with a little bit of ice.

Iggy posted a pic of her fingers enveloped in 7 diamond bands.

Iggy captioned the pic, "He told me pressure makes diamonds," and tagged the rapper and his jeweler, Iceman Nick.

Iggy's played coy up to this point, calling French a "friend," despite their makeout trip to Mexico a few weeks back ... but diamonds clearly make it official.

Kim Kardashian is walking around with over $5 million on her fingers now that Kanye West hit her with another massive diamond ... just because he loves her.

TMZ has learned Kim's new Lorraine Schwartz rock is 20 carats -- 6 carats bigger and cost 3 times more than her $1.3 million engagement ring.

Sources close to the jeweler tell us the emerald cut rock is a type IIa diamond, which means it's pretty rare and close to flawless.

Seems it's pretty rare for Kim to double up, but she was seen wearing both rocks at a Harper's Bazaar party on Sept. 9.

Insurance is a bitch.

Lindsay Lohan is back to flashing her engagement ring and raising a lot of questions -- like is she back with Egor Tarabasov?

Lindsay was out in London Wednesday where she was sporting the emerald rock Egor gave her. She hasn't been seen with him since she fled England in July on the heels of their blowout fight.

And remember ... Lindsay had ditched the ring for another one just a couple weeks ago.

The guy who allegedly made off with $3 million in jewelry from Drake's tour bus made it onto the rapper's bus because the tour bus driver thought he was part of Drake's entourage.

According to court docs ... at around 11:15 PM the driver says he saw Travion King board the bus. Travion didn't ask for permission, so the driver assumed Travion knew the performers.

The driver had remained with the bus so he left the tour bus door unlocked.

The docs refer to security camera footage of Travion walking toward the parked bus without a briefcase ... then 2 minutes later walking away clutching the briefcase containing the bling.

An international jewelry heist is over -- at least partially -- and the break in the case came when a very expensive piece of jewelry broke.

Faisal Abdulla Al Henzab -- the Consul General of Qatar -- became a crime victim back in 2013, when thieves broke into his L.A. house and stole more than $48k in jewelry and watches belonging to him and his wife.

The case went cold for a few years, but a $20k women's Rolex belonging to the Consul General's wife turned up recently at the Rolex watch service center in Bev Hills.

So here's how the case was cracked. The Consul General smartly had serial numbers for the stolen watches, and the Bev Hills detective notified Rolex and had the digits entered into the computer system. Someone from the service facility flagged the watch as stolen.

The good news ... the Consul General's wife got the watch back. Bad news ... the other jewelry is still missing and the suspects haven't been caught. The LAPD obtained a search warrant for the info that will lead them to the person who brought the watch in for repair.

Some kids eat from a silver spoon, but Too Short and Ray J are making sure their manager's newborn learns to tell time from a shiny new Rolex.

Their manager, David Weintraub, and his fiancee, Mallory Knighton, just had their first kid -- a baby girl named Stevie Rose -- and we're told Short and Ray decided to go halfsies on the $15,000 timepiece.

It's covered in diamonds and white and yellow gold, with a sapphire face ... in honor of Dave and Stevie's birthstone.

The deep-pocketed uncles have set the bar high. Our advice -- start saving now for Stevie's sweet 16.

Drake flatly denied getting "robbed" ... and technically he's right although he's clearly dodging the point.

Drake showed up with Rihanna at The Nice Guy in WeHo Wednesday night, when our photog asked about the $3 million jewelry heist that went down earlier in the day.

Two problems with the question ... he was not "robbed" since that requires force to get something and this was more like a burglary. Second, the victim is Drake's DJ, who owned the bling.

The guy who allegedly nabbed $3 million in jewelry from Drake's tour bus just got arrested ... TMZ has learned.

The suspect, Travion King, was arrested on campus at Arizona State University Wednesday afternoon, and cops describe him as a transient.

Police say they found him with the briefcase which contained all of the jewelry. He's been booked for felony burglary.

As we first reported ... cops say the loot -- which belonged to Drake's DJ, Future the Prince -- was lifted from one of Drake's tour buses parked outside the Talking Stick Arena in downtown Phoenix.

We're told King has worked for the arena in the past for concerts ... but he was not working during Tuesday night's Drake-Future show.

We got video of Drizzy going off on someone on his security team after he learned about the heist.

9:15 AM PT -- Cops tell us they got a couple of names twisted ... the jewelry actually belonged to Future the Prince, Drake's DJ on the tour ... not Future.

Honest mistake.

Drake went ballistic early Wednesday morning after learning one of his tour buses was targeted by thieves, who made off with 2 to 3 million dollars in bling.

Drake and Future were performing at the Talking Stick Resort Arena in Phoenix Tuesday night when a thief or thieves made it onto a bus shared by the 2 rappers. They took a briefcase that contained millions of dollars in jewelry.

We're told the jewelry was Future's, but the video is clear -- Drake was super upset when he learned about the heist.

Von Miller may have started an expensive new trend on the Denver Broncos defense ... 'cause one of his teammates just got himself a brand new diamond grill ... and TMZ Sports has the pics.

You already know ... Von spent roughly $100k on insane mouth jewelry this off-season ... and now we've learned cornerback Bradley Roby got himself a shiny new piece as well.

We spoke with Scott Spira at Cooka T Grillz who says Roby wanted something special to kick off the 2016 NFL season ... so he hooked him up with a 14 karat white gold piece with 220 diamonds in it.

The Denver Broncos ... diamonds in their mouths ... and on their fingers.

Lindsay Lohan is out in Greece showing off a new ring ... and it doesn't look a thing like the engagement rock she got from ex-fiance Egor Tarabasov.

Bikini-clad Lindsay was in Mykonos this week with a yellow gem on her left ring finger. She's reportedly been hanging in Greece with restaurant owner Dennis Papageorgiou ... fueling rumors she's moving on from Egor after their blowout fight.

Y'know what Egor's thinking -- where the hell's my emerald??!!

Sean Kingston has no problem picking out tons of high-end jewelry, but paying for it is another story ... according to the high-end jeweler who says they got screwed.

NYC jeweler Aqua Master just sued Kingston over 9 pieces of jewelry he scooped up last month -- valued at more than $300,000. The jeweler says Sean promised his biz manager would wire money to pay his tab.

According to the suit, Aqua got 2 checks instead of a wire transfer ... and they bounced. Meanwhile, Sean was enjoying 2 diamond necklaces, a few gold chains, a ring, a bracelet and 2 watches. A rep for Aqua tells us Sean even flaunted the goods on IG.

The company is suing Kingston and his company, coincidentally named ... Time Is Money Entertainment.

This is old hat for Kingston, who was sued by a Florida jeweler in March, and also ordered to pay another NYC jeweler for an unpaid bill.

Sean's rep hasn't gotten back to us -- but on Raq Rants he explained why so many jewelers have beef with him.
