<p>[QUOTE=&quot;Bronwen, post: 346539, member: 5833&quot;]Thought I&#039;d put this up because it is such an oddity.&nbsp; I mentioned it in an earlier post.&nbsp; I have seen well carved shell cameos whose background layer was breaking up salvaged by removing the shards of brown &amp; mounting the remainder in a custom built prong setting, &amp; a couple that were broken out &amp; affixed to a geode slice.&nbsp; This looks like it is mounted on chalcedony, but it is really glass.</p><p><br /></p><p>I suspect an impression was taken of the intact piece before the brown background was chipped away.&nbsp; The glass is not a flat slab; it curves &amp; dips just the way shell typically does &amp; follows the back of the figures - a mother or big sister trying to write while son/little brother wants to show her a bird - perfectly, no gaps.</p><p><br /></p><p>The glass is milky, almost opalescent, taking color from what&#039;s behind it.&nbsp; Some intaglios are described using the word &#039;nicolo&#039;; they look blue but are really a thin white layer over black.&nbsp; Sitting on a black background, this cameo shows the same effect.</p><p><br /></p><p>[ATTACH=full]117030[/ATTACH][/QUOTE]</p><p><br /></p>
