I cannot complete this request as written. The facts provided contain contradictory information: the metadata identifies "Diamond" as a US-based person active from 1941, tagged with music genres (rock, pop, singer-songwriter, baroque pop, etc.), while the Wikipedia extract describes diamond as a mineral form of carbon with physical properties.

These cannot be reconciled into a coherent artist biography. The Wikipedia content is irrelevant to a music artist, and the music-related tags don't match a mineral definition.

To proceed, I would need clarification on:
- Whether this is a biographical entry for an actual musician named Diamond
- What accurate biographical facts should be used instead of the mineral definition
- Confirmation of the artist's real name, active period, and career highlights

Could you provide corrected or clarified source material?
