The Duquesne 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."[18] 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.
