Dear Orchid List:

    We have discussed the half dozen PGEs (Platinum Group Elements) on
    BC-FREE-MINERS-AND-MASONS yahoogroup 

    Amazingly, though they are all called "platinum", some of them weigh
    2x the others! The SG of palladium is 12 but the SG of osmium is 23. 

    Also there are colour variations. 

    Are there jewellers here who can comment on differences in working
    with them in small sizes and shapes? 

    One reason I am asking is that I will be doing some prospecting in
    the area of Princeton, BC this spring. The Tulameen River there is
    only the second river in the world which has produced commercial
    quantities of PGE. Yet the "mother load" in the surrounding mountains
    has never been found. The more I know about the "behaviour" of PGE,
    the more likely I will succeed. 

PtP
