The two-bedroom duplex owned by late designer Kenneth Jay Lane, best remembered for creating sought-after costume jewelry, hit the market for $3.2 million. The apartment, located at 23 Park Avenue in the James H. and Cornelia V. Robb House, was designed by legendary architect Stanford White. Constructed in 1891, the mansion boasts a beautiful Italian Renaissance Palazzo style. The co-op, where Lane passed away in 2007 at age 85, sits on the second and third floors of the landmarked building, as the New York Post reported.
