A gem among gems, offered is an authentic Super Bowl ring belonging to former Dallas Cowboys defensive lineman Tony Casillas. The ring is stamped 10k made by Balfour (LGB10K) with all real diamonds totaling 5.26 karats in the shape of a football with the Cowboys' star in the center. The bezel of the size 12.5 beauty reads "DALLAS COWBOYS," the right shank bears his name and an NFL crest surrounded by the team's total record of 16-3, beneath which his position is denoted by "DT" and his number "75." The left has "WORLD CHAMPIONS 1992" and a Super Bowl logo above the final score of their victory over the Buffalo Bills, "52-17." The entire piece weighs a hefty 40.5 grams. Though he played just three of his 13 NFL seasons with Dallas, that tenure resulted in a pair of Super Bowl titles. This ring is accompanied by an LOA from Casillas.
