<p>[QUOTE=&quot;Bronwen, post: 8476886, member: 5833&quot;]I&#039;ve done it before, go around the house &amp; shine a UV flashlight on everything, but your post about the milk glass prompted me to think about it again &amp; to wonder whether I&#039;d investigated stuff in one little cabinet.&nbsp; Have discovered that you can tell real from fake pearls this way: artificial will just reflect back the purple light; real pearls will absorb it &amp; stay bright looking, maybe a little blue.&nbsp; The big discovery is that the turquoise in a pair of earrings pops up a bright veined blue when other stones right next to it just look dark a faintly purple.&nbsp; Surprised me.&nbsp; Does not look like howlite or glass.&nbsp; If I can photograph sometime, will post to jewelry forum &amp; see what I can learn.[/QUOTE]</p><p><br /></p>
