University class ring was first adopted in the 1920s, the same decade as the seal and alma mater. The first incarnation was approved by a 1925 student committee, and was an "octagonal deep blue stone held in place by four corner prongs." Two years later, another student committee replaced the blue stone with a synthetic ruby. The ring's design continued to evolve until 1936, as the prongs were replaced with a continuous metal bezel. The words "Duquesne", "University", and "Pittsburgh", accompanied the graduation year around the four sides of the bezel, and the shank on both sides was decorated with a motif adapted from the university's coat of arms. Originally an option, the embossed gold Gothic initial "D" became standard in the late 1930s. The Duquesne alumni website notes, "The golden initial, oversized stone and octagonal shape make the Duquesne ring stand out from those of other colleges and universities."
