New York (CNN) -- Given the pedigree of 740 Park Avenue's past and present residents -- John D. Rockefeller Jr., philanthropist Irene Guggenheim, designer Vera Wang and businessman David Koch, to name a few -- it's no surprise the jewelry taken in several thefts since May is primo stuff:
-- His and hers Patek Philippe watches, a Rolex watch and diamond earrings and a diamond necklace (more than $100,000 total)
-- Diamond bracelet and rhinestone pin ($82,400)
-- Two diamond earrings and other jewelry ($53,000)
-- A $7,500 wrist watch
New York City Police are investigating grand larceny robberies at the most exclusive of Manhattan addresses. There were no signs of forced entry, according to Sgt. Carlos Nieves.
