    It will depend on how the platinum ring was made and what alloy of
    platinum it is made from ( there are at least half a dozen in common
    use in the US). Some platinum alloys approach medium carbon steel
    for hardness and are harder than any other common jewelry metal  but
    the majority of cast platinum rings are very soft and scratch. bend
    and dent easily. On the white gold side it also depends on the
    alloy. Nickel white golds are quite hard and will not easily dent or
    bend. The down side is that they are not very white and are in need
    of Rhodium plating to look "white" so the plating wears off fairly
    fast and the ring ceases to look very good where it is worn. Also a
    significant portion of the population has a severe skin reaction
    with nickel and will not be able to wear it.  Most palladium white
    golds are grey (just a little bit darker than platinum) not white
    but they are much softer than nickel white. So It all depends on
    what alloys you are referring to.
