    Usually, depending on the quality of the tester, I would think only synthetic diamond and moissanite would trip a false positive.

    They should also flouresse when exposed to long/short wave ultraviolet light.
    Have seen diamonds flouresse in blue, green, yellow, orange, and white.
    Beware CZ's flouresse in orange, also
