(ANSA) - BELGRADE, AUG 28 - The search for two men who stole a valuable necklace from Vienna's MAK, the Museum of Applied Arts, is still ongoing. The two are still on the run, and police have launched a massive search operation to find them. The stolen jewel is Queen Nazli of Egypt's famous diamond necklace, created in 1939 in the Art Deco style by the Parisian house Van Cleef & Arpels. Viennese police confirmed the object's identity but did not provide any information about its value. According to Sotheby's auction house database, the necklace sold for $4.3 million in New York ten years ago, which is equivalent to approximately €3.7 million today. The jewel is made up of over 600 round and baguette-cut diamonds set in a sunburst pattern. Queen Nazli ordered it, along with a matching tiara, for her daughter Fawzia's wedding to Iranian Crown Prince Mohammad Reza Pahlavi, the future Shah of Persia. The two thieves entered the museum disguised as regular visitors. Shortly after 2:00 PM, they smashed a display case in front of several witnesses, stole the necklace, and fled unnoticed. The Vienna Regional Criminal Investigations Office is handling the investigation. (ANSA).
