<p>[QUOTE=&quot;Simona Buhus, post: 4503009, member: 17467&quot;]Thank you so much, that make sense.</p><p>The first one looks like Ruby, glows like Ruby in UV light (lights up like a lightbulb), but not pink red, it lights up yellow to orange. Is there any other spices of <b>corundum that reacts that way?</b></p><p>2. I am sure it’s not glass, it’s a stone, feels heavy and I read here to test it with a diamond tester, which I did, and it goes up one line, glass does not react on my diamond tester. In first look I would say it’s Quartz, but then the colour display of green and red, it’s quite something.</p><p>Please let me know your thoughts.</p><p>[ATTACH=full]394271[/ATTACH][/QUOTE]</p><p><br /></p>
