>     So, can we take ordinary hematite/hemalyke and magnetize it? 

    Um, Betty, what is hemalyke?   Hematite is a natural stone, composed
    of iron oxide.  Is hemalyke an imitation of it? Or some odd marketing
    term you've found? It's not a name I've seen in any of the gemological
    literature... 

    If it's an imitation, then who knows if it's magnetic.  Depends on
    what it is. If glass, then no.  If pressed steel, (which can look
    surprising like hematite once set in silver), then perhaps yes (not
    all steel is magnetic) 

    As to hematite itself and magnetism,  hematite is not magnetic, nor
    is it attracted  by a magnet.  You cannot magnetize it like your
    scissors.   While it, like magnetite, is iron oxide, the formulas
    aren't the same.  Magnetite is 46e3O4, while Hematite is Fe2O3.    
    Aside from magnetite, the only other mineral which is noticably 
    magnetic is pyrrhotite, FeS.
