The Heist
A daylight robbery unfolded at the Museum of Applied Arts (MAK) in Vienna when two men entered the Van Cleef & Arpels exhibition, smashed a glass case with a hammer and fled with a platinum-and-diamond necklace. Austrian police released CCTV images showing the unmasked suspects—slim men with short beards and dark hair—leaving on foot toward the nearby Stadtpark. One thief was believed to be carrying a firearm. No visitors or staff were injured. The exhibition was briefly closed and a blue panel was installed over the damaged case.
Background & Context
The stolen piece was a 200-carat necklace set with 673 diamonds, commissioned by Van Cleef & Arpels for Egypt’s Queen Nazli in 1939 and later worn at Princess Fawzia’s wedding. After Nazli’s death, it resurfaced at a Sotheby’s auction in 2015, fetching $4.3 million. The necklace was on loan to MAK as part of an exhibition running from June 10 to September 27.
