Hi Cathy, 

    Sorry...can't buy in to "blue quartz" Quartz is never blue unless it
    has some other mineral mixed in with it. I guess maybe we have a
    semantic issue here;quartzite  can sometimes be blue, but only if it
    has some mineral that is mixed with it. Chalcedony can be blue, but
    it is not a common color. (Blue chalcedony is very pricey stuff ! )
    Blue chalcedony has a widespread occurrence in Southern Africa, but
    most of it is banded material that is too pastel to be classified as
    being essentially blue) Unfortunately, chalcedony is very receptive
    to dyeing  therefore it can be had in just about any color)
