Norah -

    Fire jade was initially (late 1940s - early 1950s) the name under
    which orthoamphibole from Wyoming was being sold. It was advertised
    under this name into the early 1960s in trade publications such as
    Lapidary Journal and Jewelry Making, Gems and Minerals. In color it
    is a mix of reds, oranges, ochres and browns; in texture it is a
    felted fibrous crystalline mass. Like its cousin nuumit from
    Greenland it is a very old rock, having been formed well back in the
    Pre-Cambrian. From your description it seems that someone has
    resurrected the name and applied it to a form of tremolite, perhaps.
    Tremolite is one of the rock forming minerals which makes up
    nephrite jade.
