    I've got some carved heads beads which are jet.  Think of jet as
    fossilized oil.  It's actually a really heavy hydrocarbon (heavy as
    the analytical chemist -- my day job-- thinks). 

    Real jet is very light and warm.  Much lighter than most plastics. 
    The beads I have are the only true jet I have seen in the past 7
    years of gem shows. 

    There are chemical tests, but they are mostly destructive.  My guess
    is that you may actually have real jet.
