    Then why is there such a difference in estate pieces in how they've
    held up?! Platinum wins hand down. I'm not talking about die-struck
    platinum either! I'm not arguing with you but I'm baffled by your
    referenced information - 10 years of looking at jewelry contradicts
    those numbers. There's got to be another factor here somehow. 

    Is it a comparison of data of equal weights? In other words, two
    rings alike in style would have a 60% weight difference due to the
    denseness of platinum but perhaps two pieces of equal weight (and
    different size obviously) might test differently because you've taken
    so much mass out of the plat sample that performance isn't the same? 

    Why do white gold prongs need retipping so much more frequently than
    plat prongs? Doesn't seem to matter what the white gold alloy is,
    retipping is common after 2-4 years. Not the case with plat at all! 

    You've made me curious! 

Thanks,
Jeanette
