    Virtually all emeralds sold today will either be oiled or fracture
    filled with one of a number of possible substances.  I can only
    recall seeing about a half doaen stones that weren't treated in the
    last twenty years and the only reason they weren't treated was
    because the treatment didn't take in the goods (they were from a
    Russian source)--in other words treatment was attempted but failed. 

    Today the differences in prices between treated emeralds is now
    often being judged by how much treatment is used but it is considered
    standard, acceptable trade practice to sell all emeralds with a
    treatment as long as it is disclosed. 

    I doubt very much that you will be able to find untreated stones
    anywhere. You just need to excersize the same type of precautions in
    wearing the emerald that you would with any delicate gemstone. 
    Incidentally, most stones can be retreated if for some reason the 
    treatment leaches out.
