This is a superb example of this rare nickel species, with brilliant hulk-green crystals to 1 cm in a protected cavity in a quartz geode. I believe this is the world's best locality for the species....at least, I have not seen good honessite from other places for sale. Honessite is MUCH more rare than the millerite found in geodes from this hard-to-collect locality (I know, I collected there as a kid!). The location is a roadcut along a major state highway, now completely off-limits to collectors.
