The ABC dating series' preview clip shows the former NFL quarterback, 27, meeting with jeweler Neil Lane to select the right rock for Fletcher, 25.
"There's a lot of moving parts today, and it's the biggest day of my life," Rodgers tells the camera. "But this is how I wanted to feel: scared in the best way, and nervous in the best way."
"Overwhelming is the right word for sitting there, trying to pick out a ring," the season-long front-runner continues. "An engagement ring is forever — it's gonna represent that promise that it's gonna be her and me for the rest of our life."
Rodgers tells Lane, "I know what we're doing, but I'm a little nervous." The jeweler then hands the aspiring sports broadcaster a ring featuring a cushion-cut diamond.
Rodgers and Robby Hayes are the two men left standing as the venerable dating series heads into its final season 12 episode. Last week's installment saw Fletcher bid farewell to Chase McNary and Luke Pell, and both castoffs have said they would be interested in taking the reins as the season 21 Bachelor.
Tell Us: Should Fletcher pick Rodgers or Hayes? And who should be the next Bachelor?
Watch Rodgers inspect the bling in the video above. The Bachelorette's season 12 finale airs on ABC Monday, August 1, at 8 p.m. ET.
