<p>[QUOTE="Bronwen, post: 815403, member: 5833"]Can't tell you how many times I have half screamed I HATE BLACK STUFF! Let's not forget black lava while we're at it. Another clue can be what the black material is being used for. If I see a conch shell cameo mounted in a shiny black surround, I can be reasonably sure it is jet, unless there are contraindications. If I see an all black cameo with a shiny surround & a matte appearing figure, often I am unable to come to a firm conclusion: is it a single piece of jet?; is it a premade jet fame with a hand cut jet cameo mounted in it?; is it a cameo molded in Vulcanite or similar, in a genuine jet mount? I look for signs of carved v. molded. I look for browning, especially in crevices; gutta percha type materials oxidize over time. Bottom line is that I buy very few items of black jewellery, just for this reason.[/QUOTE]</p><p><br /></p>
