I wanted to add this too, as per what Alfredo said. In addition to needing a smooth (preferably polished) surface (I don't know how they'd perform on a rougher surface), there are only a dozen or so minerals shown on that meter's scale, and of course there are "hundreds" of possible minerals/gemstones. As you say, M, jadeite is not common in NC, and I think it would be very rare to "scarcely ever" to find a piece of jadeite in a stream bed there. I think specific gravity will be your best bet, to at least eliminate some mineral possibilities, and give you a list of "possibles".

Thanks, everyone. Specific gravity was 2.62 (crappy scale but confidently it is not anything else besides green quartz / aventurine). Thanks so much!

Solved: Green quartz or aventurine
