    Any ideas as to whether the (allleged) Palladium (SG 12) allergy
    also generalizes to Platinum (SG 22); Iridium (SG 22/23); Rhenium (SG
    21); Rhodium (SG 12); Ruthenium (SG 13)? 

    Also, does it generalize to the Platinum-like metal, Rhenium (SG
    21)? 

    The SG of gold is 19. 

    Though Rhenium is as rare and costly as the PGEs, it is not
    classified as a PGE. Has anyone worked with it in metallurgy or
    jewelry? 

    PGEs have not yet been assayed for in the human body to the best of
    my knowledge but maybe there are some cutting edge assays. Anyone
    know? Most of the elements in the soils and rock dusts are found in
    the human body.
