[Jewelry making - Article 00295] - [Orchid] PVD and color CZs

    Yesterday at the MJSA show, I found some lovely new colors of CZ,
    both in terms of "colored CZ" and as PVD coated CZs.  I don't use
    them all that much, but do have a couple of customers who really like
    them, so would like to learn more about them. 

    I have 3 questions, in particular. 

    1.  I have successfully cast white CZs in place (in silver and
    gold).  Can this be done with colored CZs?  How about PVD coated CZs
    (my guess is no, but I don't know enough about the PVD process to
    know for sure)? 

    2.  Is PVD coating on CZ pretty much the same as PVD on topaz? 
    (i.e., it will eventually abrade off if set in a way that exposes the
    stone to rubbing or contact) 

    3.  So how DO you color a CZ?  I've assumed that the color is added
    as the CZ is being created and therefore permeates the stone -- but
    is that true? 

    Thanks for any insight you folks can give me - I'll be playing with
    them in the coming weeks and would like to know in advance what to
    avoid. 

Thanks!
