Blue Ivy Carter made her Met Gala debut on Monday night, hitting the red carpet with high-fashion parents Beyoncé and Jay-Z.

The 14-year-old wore a strapless, bubble-hem white dress with a matching bomber jacket, all by Balenciaga — and a single statement necklace that wowed.

The necklace is British jeweler Henry & Henry’s one-of-a-kind Riviere Diamond Necklace, which features a 5.39-carat yellow diamond center stone, surrounded by a graduated line of classically bright white diamonds.

Set in 18-karat gold, the necklace is designed in the Georgian style with a cut-back setting.

According to the brand’s website, the piece is a “a modern heirloom of extraordinary luminosity.”

Page Six Style did not immediately hear back from reps for Henry and Henry about the price of the piece.

Meanwhile, mom Beyoncé — who was a co-chair for the evening — pulled out all the stops when it came to her jewelry.

The “Cowboy Carter” singer wore part of a $50 million Chopard necklace, featuring cuts from the 342-carat rough Queen of Kalahari diamond. She piled on more impressive Chopard diamonds and emeralds and glittered in a custom Olivier Rousteing skeleton dress.

In addition to her show-stopping necklace, Blue Ivy also accessorized with layered rings and a pair of sunglasses that she only removed once she reached the top of the stairs — like a true pro.
