"Diamonds & Rust" is a song written and performed by Joan Baez. It was written in November 1974 and released in 1975.
In the song, Baez recounts an out-of-the-blue phone call from an old lover, which sends her a decade back in time, to a "crummy" hotel in Greenwich Village; she recalls giving him a pair of cuff-links, and summarizes that memories bring "diamonds and rust." Baez has stated that the lyrics refer to her relationship with Bob Dylan.
