Now the NYPD wants to locate the couple and return the ring to them.
Police in NY have taken to social media to track down a man who dropped an engagement ring through a grate in Times Square as he knelt down to propose.
They managed to recover the stunning ring on Saturday, and cleaned it up.
Trouble is, police didn't have the names or contact information for the couple.
Police say the man had just proposed to his girlfriend in Times Square on Friday when he accidentally dropped the ring down a utility grate.
When the couple asked police for help, emergency service officers could not immediately find the ring - but continued looking after the couple left.More news: Divisive race in Mississippi ends with win for GOP Sen. Hyde-Smith
