<p>[QUOTE=&quot;Any Jewelry, post: 339607, member: 2844&quot;]Apparently the most conclusive test for coral is with a spectroscopy microscope.</p><p>I have used the acetone test on different coral beads, it has worked with all of my suspect coral so far.</p><p>You press a cotton bud with acetone on the same spot of the coral for 20-30 seconds. Some sites say rub, but I find that pressing for a longer time works better because the acetone stays in one spot. If the cotton bud is stained, the coral is dyed. This method won&#039;t remove all of the dye, the coral still looks the same.</p><p><br /></p><p>I can imagine, I prefer salmon coral as well. And love angelskin coral.<img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie49" alt=":happy:" unselectable="on" unselectable="on" /></p><p>I know red coral can be professionally bleached. Some Dutch bead sellers order their Italian red coral bleached to the darkish salmon colour, which is preferred here in the Netherlands. I have no idea which method is used, just that it is done in Italy.[/QUOTE]</p><p><br /></p>
