Hi:

    Having hunted extensively for blue calchadoney AKA ELLENSBURG BLUE,
    I have found that true blue coloration by iron ion4 will have a
    yellow to pinkish glow in the finished piece. I have found the
    extremes to be carnelian on one end and almost purple on the other.
    the way to tell if they are true is to look for growth lines or in
    the case of pure gel deposit clarity that will carry the glow. Blue
    quartz on the other hand can be colored by other minerals that do
    not carry the glow but almost always show lines of growth. I have
    found deposit and pieces that carry that effect throughout the state
    Of Washington.
