Massachusetts Institute of Technology's class ring, often called the Brass Rat, is redesigned each year by a student committee. The class ring has three main sections: the bezel, containing MIT's mascot, the beaver; the MIT seal (seal shank); and the class year (class shank). The side surfaces show the Boston and Cambridge skylines. An MIT campus map and the student's name are engraved on the inner surface. The phrase "Brass Rat" is derived from the alleged resemblance of the gold beaver to a rat. Among other reasons, the beaver was chosen as mascot (and therefore for the front bezel of the ring) because he is considered to be the engineer of the animal world.
