An alleged international jewel thief wanted by Interpol was busted after stealing rings worth a total of nearly $300,000 from the Cartier and Tiffany stores in Manhattan, prosecutors said Sunday. Yaorong Wan, 49, used sleight-of-hand at Tiffany & Co. at Rockefeller Center to swipe a diamond ring worth more than a quarter-million dollars, then hit the Cartier store in the Hudson Yards a week later, prosecutors allege. Wan, who was using a false identity when police caught up with him Friday, has made a name for himself as a sticky-fingered serial thief, Assistant D.A. Eliana Ramelson explained at his Manhattan Criminal Court arraignment Saturday. He’s the prime suspect in a series of Cartier store thefts in California and Miami, had a Red Notice from Interpol for high-end jewelry store heists in South Korea, and he’s wanted in similar crimes in Nassau County and New Jersey, the prosecutor said Saturday. He walked into the Fifth Ave. Tiffany store on March 4 and asked a woman working there about several items, according to a criminal complaint. He asked to see the ring, which held a natural diamond mounted in platinum, then handed it back and left without buying anything. A week later, workers doing a routine inventory realized the ring was swapped out for one a cubic zirconia stone, and that the ring mounting was 18 carat white gold. Surveillance video showed the crook slip the real ring worth $255,000 into his palm and make the switch, according to the complaint. The Cartier store at Hudson Yards in Manhattan.
