    Colored CZs, I don't see why not. I don't think they would be
    affected, but it would be a very small price to pay to find out. I'm
    guessing on PVD too, and my guess is exactly the same as yours. But
    again, it'd be a small price to pay (especially in silver).

    Yes

    Yes, trace elements are introduced in the manufacturing process.
