Michael Rubin’s Fourth of July white party on Monday featured more than just fireworks.

Kim Kardashian arrived at the star-studded event wearing a Messika diamond necklace set with a stunning 17-carat pear-shaped stone that she cleverly fashioned as a belly chain.

Kim Kardashian wrapped a pricey diamond chain around her waist to celebrate the Fourth of July this week.

The Skims creator, who ended up twinning with another Kanye West ex Chaney Jones at the party, previously wore the identical garment to the Time 100 Gala in April, but she wore it around her neck that time.

According to the jeweler, the piece was designed to be worn in several ways, and Kardashian used its versatility to highlight her tiny waist at the Hamptons celebration.

Kardashian showed off the blingy chain in a TikTok on pal Lori Harvey’s account.

She originally wore the piece as a necklace, layering it with more dazzling diamonds for the Time 100 Gala this year.

Diamond Pro CEO Mike Fried tells Page Six Style that the versatile piece is likely worth $1.3 million.

“Any diamond over 15 carats, especially a pear-shaped one like Kim’s, is extremely rare,” he warns.

Olivia Landau, GIA-certified gemologist and proprietor of The Clear Cut, gave us an even higher estimate for the “epic” bauble, saying it “could range from $2 to $3 million, depending on quality.”

The reality star posed with her sister, Kendall Jenner, and plenty of famous pals at the party.

Kardashian styled the chain with a sheer white Alaïa crop top ($1,860) and ribbed skirt, wearing it atop the low-slung bottom.

Meanwhile, her ex-husband’s former flame, 24, wore the dress version ($4,320) of the same outfit to Rubin’s party, though it’s unclear if the two crossed paths.

The Skkn by Kim founder, who claimed on Twitter that she took nearly a dozen shots at the drunken blowout, unveiled her Alaïa costume in a pre-party TikTok on Lori Harvey’s account, dancing, strutting and drinking with sister Kendall Jenner and friends Harvey, Hailey Bieber, Lala Anthony, and Justine Skye.

Kardashian seemed to be having a blast with Hailey Bieber and Lori Harvey ahead of the party.

She originally wore the diamond necklace/belly chain with a John Galliano dress.

One member on the KUWTK Snark Reddit thread questioned Kardashian’s Y2K accessory, saying, “Kim is really trying hard to make the year 2000 belly chain a ‘thing’ again.”

“Belly chains are definitely back in trend, and I think they’re cute when done appropriately. “So not like this,” another remarked.

“Belly chains ARE a thing again,” one admirer said in support of Kardashian. “Very Y2K lol.”

Kim clearly enjoys the two-for-one sparkler.
