Jun 03, 2011 · All this talk of coal and limed coal has got me to thinking. If it is the calcium in the lime or metalic impurities in the coal that causes the detector to "see" it that is one thing, but if the Carbon in the coal is conductive enough to set off the detector, then it seems to me that a diamond might set off the detector as well.
