<p>[QUOTE=&quot;Marko, post: 367611, member: 210&quot;]I love that owl. The red stones do fluoresce bright red under black light, so I am ruling out garnet and red topaz.&nbsp; I cleaned it, and it does test in the ruby range, thanks mforjan.&nbsp; Eveleyb, I didn&#039;t think of zircon...&nbsp; I do love blue zircon, and have a couple....I will have to wait for a jeweler or two to weigh in.&nbsp; Cleaned it is even more beautiful to me.&nbsp; The diamonds are stunning.&nbsp; I will keep you posted.&nbsp; The Black Prince&#039;s stone is red spinel, which is found with ruby deposits....I have been researching what this could be....</p><p><br /></p><p><font size="6"><b>THE GEMSTONE SPINEL</b></font></p><p>Spinel is most famous for its deep red variety that closely resembles <a href="http://www.minerals.net/gemstone/ruby_gemstone.aspx" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.minerals.net/gemstone/ruby_gemstone.aspx" rel="nofollow">Ruby</a>. These two gemstones can be very difficult to distinguish. Until the late 19th century, there was no distinction made between Ruby and red Spinel, as they look identical and are found in the same localities. Many famous old &quot;Rubies&quot; were discovered to be in fact Spinel. For example, the enormous &quot;Ruby&quot; that forms the centerpiece of the royal crown of England (the Black Prince&#039;s Ruby) was actually determined to be Spinel.[/QUOTE]</p><p><br /></p>
