On Friday night, a Christmas Eve proposal gone awry has a St. Petersburg couple searching for a missing engagement ring near the St. Pete Pier. "It almost doesn't feel real," Erik Lightle said. He'd been planning a thoughtful Christmas Eve proposal for months. "It's our family day," Lightle said. "It's the day we picked up our golden retriever, Knox, a year ago. I thought that would be a good day for us to take another step forward as a family." He came prepared with a diamond ring, with a black diamond halo, custom-made for Olivia Harms, based on what he'd seen on her Pinterest page. "He knew I loved black diamonds and wanted something different and he went off of that," Harms said. "It came out really great," Lightle said. "It looked really unique, in my opinion, and it's just a shame it's not on her hand right now." The proposal began with the couple's dog carrying a note on his collar for Harms to read. It asked her whether she would marry "his dad." Then, when Lightle went to kneel in the park, he noticed something was wrong.
