Tom,

    I also do not feel comfortable selling some of the gems with
    treatments that are on the market but unfortunately most gemstones
    are treated in some fashion.  There are a few exceptions such as
    Peridot, Garnet, Iolite etc. 

    There is no problem selling lapis treated with Paraffin wax as long
    as you disclose it to your clients. I for one do not like to sell
    any gemstone treated with paraffin. 

    As for the difficulty of getting a good polish on Lapis, this
    gemstone easily undercuts as you are polishing it.  You need to take
    your time and use  laps that gradually get finer and finer.  It is
    difficult to try to jump from say a 1200 grit lap right to a final
    polish. Try laps that gradually go up to a 50000 grit diamond and
    see how that works. 

Good Luck
