In the United States, Canada and other countries, a class ring (also known as a graduation, graduate, senior, or grad ring) is a ring worn by students and alumni to commemorate their final academic year and/or graduation, generally for a high school, college, university and organization. Today class rings can be customized, from the material and style that the ring is made of to the color and cut of the gem in the center or no gems. There is a wide selection of emblems, pictures, and words that can be added to the sides of the rings and even inside the center gem. Sometimes a boy will give his girlfriend his class ring to wear, a custom that has become a cliche.
