MIT class ring

Massachusetts Institute of Technology's class ring, often called the Brass Rat, is a commemorative ring for the graduating class of students at MIT. The ring is redesigned each year by a committee of MIT students. 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. On earlier versions, the Building 10 facade was featured on each shank, with "MIT" under it on one side and the class year on the other.
