This is a very rich example of millerite nestled within a protected cavity in a quartz geode. This is a hard-to-collect locality (I know, I collected there as a kid!), and geodes this full and this well- filled are just rare as can be. The location is a road cuts along a major state highway, now completely off-limits to collectors. This particular specimen has millerite poking out all sides, and is delicate to mail, so best sold for hand-delivery at some time as possible.
