<p>[QUOTE="Ce BCA, post: 4180548, member: 18716"]Looks right to me for nephrite. Just a general note, I have one of those meters and they are very inaccurate - temperature, humidity and even if you are grounded or not can make a big difference to the readings. If you do a lot of stones get a microscope (which you can also easily use as a polariscope) and a refractometer, this will give you much better results you can be confident in.[/QUOTE]</p><p><br /></p>
