Hey Rob O Actually, I'm more of a humorist than a musician, but, I get by among the more forgiving..THE DIAMOND is a song I used to sing years ago, and, for some reason it was a favorite with my youngest little girl. The chords I used were: Am Em G Am Em Am in that progression for the verses. Then for the refrain: Am Em back to Am I'm sure a real musician could really dress it up, but it's the best I can do.
