The design on the top of Michigan State's Cotton Bowl championship ring replicates the trophy the Spartans took home for beating Baylor 42-41 in the Jan. 1 game.
On one side of the ring is the bowl game score and the Spartans' final record of 11-2.
On the other side is MSU's final AP ranking (fifth), as well as the score from the Spartans' 2014 rivalry game against Michigan, 35-11.
MSU linebacker Darien Harris posted photos on Twitter that showed all three sides of the rings.
MSU says the rings were designed by coach Mark Dantonio and the football team's leadership council.
MSU has had a ring made in each of the last four years, to commemorate bowl victories.
Each ring has the bowl score and the score from the game MSU considers its next most significant triumph.
For the 2013 season, MSU included the Ohio State win in the Big Ten championship game with the Rose Bowl win over Stanford.
