The Buckeyes won the game 34-23, making it their first national title since 2014.
Rings were revealed during the team's spring game.
Head coach Ryan Day, who signed a new seven-year deal in the offseason that's worth just under $88 million, said, "It puts a smile on your face when you see it."
A couple of new banners were also added to the team's tunnel inside their stadium.
Ohio State took down #9 Tennessee, #1 Oregon (who they lost to during the regular season), and #5 Texas before eventually taking down the #7 Fighting Irish of Notre Dame - winning each College Football Playoff matchup by two scores or more.
After finishing with a 14-2 record and a ring, the team will visit the White House on Monday in Washington, D.C., as is (usually) customary for college champions.
