<p>[QUOTE=&quot;desertgem, post: 1837574, member: 15199&quot;]Thank you for the specifications. Many people who resort to testing such as &quot;ring&quot;, rare earth magnets, observation under tissue paper, do not understand the physical chemistry involved with specific gravity, nor have they invested in accurate scales with high resolution , nor similar digital calipers. Such measurements would have greatly relieved any suspicions, if they would have done so. Most have scales with a resolution of only 0.1 grams and thus fall short due to rounding algorithms. </p><p><br /></p><p>Do you happen to know the tolerances involved with the measurements you quoted?[/QUOTE]</p><p><br /></p>
