<p>[QUOTE=&quot;evelyb30, post: 2909174, member: 36&quot;]Brutalist pewter pendant is as good a guess as any from here. The stones could sometimes be real; turquoise wasn&#039;t respected for a while and often turned up in costume settings.&nbsp; These are glass.</p><p><br /></p><p>The top one wants to be amethyst and hematite but I suspect hematite and glass unless it&#039;s glass all around.&nbsp; If the grayish beads stick to a magnet, they&#039;re hematite.&nbsp; If not, they&#039;re glass.&nbsp; Hematite is an iron compound; they rust eventually. Those chip beads are just too red for most amethyst.&nbsp; </p><p><br /></p><p>The piece made in Thailand is silver with &quot;enhanced&quot; semi-precious stones.&nbsp; A lot of citrines (yellow) are heat-treated to improve color.&nbsp; The peridot too.&nbsp; Blue topaz is irradiated and heated 99% of the time or better to change it from clear to blue.&nbsp; The amethyst and garnets are probably natural; no one bothers messing with those for the most part.&nbsp; No point. </p><p><br /></p><p><a href="https://www.gia.edu/topaz-quality-factor" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.gia.edu/topaz-quality-factor" rel="nofollow">https://www.gia.edu/topaz-quality-factor</a> (if you want the skinny on topaz)[/QUOTE]</p><p><br /></p>
