Kim Kardashian was flashing the bling in a very conspicuous manner over the 4th of July holiday weekend.

The 42-year-old reality TV siren wore a very rare 17 carat pear-shaped diamond around her waist from jeweler Messika as she hit Michael Rubin’s white party in the Hamptons in New York alongside sister Kendall Jenner. The rock is estimated to be worth around $2M.

The company shared with DailyMail.com that the ‘belt,’ as they called it, was custom made just for the Keeping Up With The Kardashians veteran. Messika added the look was a collaborative effort between Kim and her stylist Danielle Levi.

This comes seven years after the mother-of-four was robbed at gun point while in a Paris hotel during fashion week that resulted in her being bound and left in a bathroom while the bandits made off with $10M worth of jewelry.

After that, Kim wore less jewelry.

The rock – which she also wore as a necklace at the Time 100 Gala – was from Messika and hung from a belly chain around Kim’s tiny waistline.

Maison Messika was founded in Paris in 2005 by Valérie Messika.

‘Daughter of a diamantaire, she lived and breathed diamonds growing up, as her father built one of France’s most successful diamond trading businesses,’ the company added.

She makes pieces to ‘highlight women’s bodies.’

Messika also works with Kendall’s close pal Gigi Hadid. Cardi B and Irina Shayk are also fans and have worn their pieces recently.

Kim was dressed to impress at Rubin’s party.

She had on a crop top that showed off her midsection, adding a matching skirt. Her raven hair was worn down and she was heavily made up.

Other high-profile celebrities in attendance included Jennifer Lopez, her husband Ben Affleck and Leonardo DiCaprio.

Michael Rubin i the CEO of Fanatics, which is known as the world’s top provider of licensed sports merchandise.

The SKIMS founder wrote on Twitter that she drank 11 shots throughout the evening while a source told DailyMail.com that she was caught mingling with newly-single NFL star Tom Brady, 45.

‘Kim and Tom were super flirty with each other at Rubin’s party and were seen during the day on the beach together and again dancing at night,’ the insider dished.

Kim and Tom were first hit with dating rumors earlier this year after several outlets reported that Kim was seeking to purchase a holiday home near Tom’s in the Bahamas.

But the Super Bowl champion’s team denied the romance and insisted they are ‘just friends.’

‘Tom and Kim have been in touch because Kim is looking to buy property where Tom has a vacation home,’ his reps said in a statement to ET in May.

‘Kim and Tom have friends and business partners in common, but they are not dating.’

Kim finalized her divorce from third ex-husband Kanye West, 45, in November, nearly two years after she filed for separation.

The former pair — who were married for nearly seven years — share four children: North, 10, Saint, seven, Chicago, five, and Psalm, four.

Kim famously dated SNL funnyman Pete Davidson, 29, from November 2021 to August 2022, but has remained single since.

A source told ET in April that Kim ‘is more open to dating again and putting herself out there’ now that she’s had time to process their split.

Kim also recently said that she hopes to avoid making the ‘same mistakes’ that she has made in her past romances.

Meanwhile, Tom and his ex-wife Gisele shocked the world last October when they announced they would be separating after 13 years together.
