    Heat treatment of sapphires, which should not be confused with any
    other treatments (i.e diffusion, oiling, etc.) is a permanent
    treatment and will effect value only slightly until you get in the
    $5000 and up range. A certificate from a reliable lab should
    generally be trusted, but you should make sure that the lab is an
    internationally recognized lab.  You should also be prepared for some
    differences of opinion between labs.  Origin reports are often a
    little dubious. Your friend should buy her stone from a reputable
    jeweler in her own country.  If you purchase a valuable stone in
    another country and come home and find it is not what it was
    purported to be you will not have legal recourse (or at least not
    easy legal recourse). 

    Ultimately however, as long as the stone is a natural stone and all
    treatments are revealed (buy at a reputable jeweler!!) she should
    pick a stone that truly moves her.  It doesn't matter where it comes
    from or if it is heated or not--if she doesn't like the stone she
    shouldn't buy it and if she does like it and it makes her feel good
    then she should.  You can have a great, expensive, beautiful natural
    color stone but if it isn't the color you want you shouldn't buy it
    just because it is certed as natural.
