When used in a metaphorical sense, the chain (or chains) almost always describe oppression or being held against one's will. We see them employed in the song "The Chains of Love" by the theatrical 1980s synthpop band, Erasure
, wherein lyricist Andy Bell describes breaking the chains of stereotypes and social restrictions. And, of course, there is the proverbial "ball and chain", an allusion to one's spouse. Used in either sense, the origin of the repressive chain comes from the 19th century prison practice of shackling captives with a heavy ball and chain to prevent them from escaping. This vintage platinum wedding band is a much sweeter expression of a chain, the four links of the face sparkle with 30 single cut diamonds. The interior of the hoop is engraved "NGU to HMR 11-11-50".
