Dear Steve & James,

    I do not have any additional information to add on Zachery-Treated
    Turquoise (see Gems & Gemology, Spring 1999, Volume 35, No.1), but
    would be very interested if either of you, or anyone else reading
    this, has a reliable source for any of the modern or unusual treated
    materials that are available these days for a reference collection? 

    Since they are for a reference collection there should be NO DOUBT
    as to the identity of the treatment method or material! Examples of
    things I would be interested in obtaining samples of are
    Zachery-Treated Turquoise, Be-Treated Corundum, KM Treated (aka:
    Kiduah Meyuhad or 'internally-lasered) diamonds, any type of polymer
    impregnated material (opal, jadeite, not turquoise so much though)
    etc... 

    Thanks for any trustworthy links you may be able to provide! 

Regards - Nick
