<p>[QUOTE=&quot;desertgem, post: 2723671, member: 15199&quot;]In the 2013 and the 2014 URL, I see an oval light spot from the left side of the vertical of the 7,across it, and on the right side, and in the 2017, it is still there, but the right side has enlarged and is more apparent. Although the &#039;plastic cause&#039; might the correct one, and a visual of it at an angle should show that, since slabs are not airtight, it is possible that it was put into a different environment which caused the apparent &#039;spot&#039; to blossom.[/QUOTE]</p><p><br /></p>
