Double Diamond is the sixth album by British jazz-rock group If and the second to be issued in the U.S. on the Metromedia Records label. With only Dick Morrissey left from the original band, the new line-up featured Fi Trench (keyboards) and Pete Arnesen (keyboards), Steve Rosenthal, Kurt Palomaki (bass) and Cliff Davies (drums). It was recorded at The Manor recording studios shortly after Mike Oldfield's Tubular Bells, and released in 1973.
