    G'day Judy Willingham; my suggestion (for what it is worth) is that
    amber is simply ancient lumps of resin from which all low temperature
    volatiles have been driven over the centuries.  If you have a piece
    of scrap, you could dissolve a very small amount in real oil of
    turpentine; not the stuff from the supermarket, but from artist's
    supply shops. Distinguishable by it's pleasant 'pine tree' smell.
    failing scrap, perhaps a little powdered ordinary resin would work
    with the turpentine as a glue.   You could treat it as lucite joins
    are treated; paint the 'pine glue' over each of the exposed broken
    faces, press together accurately, then with the piece resting on foil,
    grease proof or other proofed paper on a small wood support, clamp it
    gently, place it in your airing cupboard - well away from the hot
    water cylinder, and leave it for a day or two. The join should be
    barely visible.   Perhaps it might be remounted in an electro formed
    bezel?  -- Cheers now, John Burgess;   johnb AT ts.co.nz of Mapua Nelson
