<p>[QUOTE=&quot;desertgem, post: 2007272, member: 15199&quot;]I still use it occasionally for gemstones and rough stones. I use a lab surplus mettler H30 with enclosed pan area and it has a usable .0001g resolution. However since some bullion places are buying something like this, one might pay a fee to have a coin zapped for analysis. Here, in So.Cal., one mining specialist on Craigs List advertises an analysis , one time for $50, or 5 for $199. </p><p><a href="http://www.olympus-ims.com/xrf-xrd/delta-handheld/delta-alloy/" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.olympus-ims.com/xrf-xrd/delta-handheld/delta-alloy/" rel="nofollow">http://www.olympus-ims.com/xrf-xrd/delta-handheld/delta-alloy/</a>[/QUOTE]</p><p><br /></p>
