"This Diamond Ring" is a 1965 song written by Al Kooper, Bob Brass and Irwin Levine.

It was first released as a single by Sammy Ambrose on Musicor #1061, then by Gary Lewis & the Playboys[1] on Liberty #55756.

[citation needed] Lewis has denied claims that the Playboys did not play on the record, and says that not only was the band largely self-contained, but the Wrecking Crew session musicians only came to do overdubs or solos.

[5] Although it has been his biggest commercial success as a songwriter, Al Kooper has reportedly stated many times that he was unhappy with the record.

Kooper would later re-visit the song, recording a funky version for his 1976 album Act Like Nothing's Wrong.
