<p>[QUOTE=&quot;desertgem, post: 903655, member: 15199&quot;]I can&#039;t wait to see what PCGS states in their patent application that makes their procedure, etc. different from existing patents. These machines&nbsp; are not as expensive as they sound~ My former community college has had a diamond window FT-IR for several years and smaller versions have replaced older models, so they may even show up on lab equipment auction sites. They have been used on ancient and modern coins, paintings, ceramic art objects, gems and minerals, etc., so their use with collectibles has been well established.&nbsp; I suspect that ANACs could also participate in their use along with NGC and not cross any patents of PCGS, IMO. </p><p><br /></p><p>These are not new tools, techniques, or uses.[/QUOTE]</p><p><br /></p>
