Gold ring with diamond found near UIUC campus

I found a gold ring this afternoon around 2:30pm outside the Krannert Center for the Performing Arts on Green Street, Champaign-Urbana. It's a 14k yellow-gold ring with a small round diamond set in a bezel, about size 6.5. The band shows light wear and there’s a tiny engraving on the inside that reads 'M.L. 04/12'. I picked it up from the sidewalk after a campus event, hoping to reunite it with its owner. If this belongs to you, please share a close-up photo of the ring or describe the inscription and a preferred meetup spot. I can return it near the Illini Union or Krannert lobby.
