<p>[QUOTE=&quot;shamster, post: 10029030, member: 85821&quot;]Hi all,</p><p><br /></p><p>I&#039;ve posted this ring before:</p><p><br /></p><p>[ATTACH=full]503632[/ATTACH] bought as a ruby ring from a well-known antiquity dealer in uk about two years ago. I never doubt the authenticity of the stone, but as today I got a chance to test it with the cheapest conductivity tester, it indicates a stone with lower hardness- around 6-8 or something. It significantly differs from other rubies of various sizes which doesn&#039;t seem like a calibration issue. It contains these inclusions one would expect from ruby and garnet, as shown here:[ATTACH=full]503631[/ATTACH]</p><p>it flashes as the ring turns and has bluish shine</p><p><br /></p><p>and it does not glow under uv light. </p><p><br /></p><p>I know it cannot be fully identified with only these, but what do you think I may have here? Do you think the &#039;ruby&#039; is stone dead given the judgement of the tester? Any chance for the tester to be wrong? The stone does not really matter for this ring, but I just want to know more...[/QUOTE]</p><p><br /></p>
