I am a novice metalsmither attempting to create my own diamond bands. I flush set some in an 18K green gold band that turned out beautifully and I want to do the same in a white colored band. I''m having trouble determining what the best metal to use may be. I don''t think white gold is the answer because it is not really white and I don''t want to have to plate it. Platinum may be beyond my budget. I recently experimented with some pure palladium and that too still looks grey to me. Is there anything else out there?
