It’s 30 inches long, doesn’t have a clasp and is very heavy at 156 grams. It tested positive with Simichrome polish, strangely has one bead marked (see second to last pic), is swirled in color, and mildly glows under UV light. At first I thought it was Bakelite due to weight and testing positive with Simichrome but it’s beaded with a twine like thread. It’s definitely not glass. Could it be Faturan?
