Fancy 6mm by 8m rectangular shaped spacer beads, with an elaborate Celtic knot design and an antique silver tone finish.
These are nicely detailed cast metal beads, made out of a zinc based metal alloy, which is sometimes sold as "lead-free pewter" or "Tibetan Silver". (The term Tibetan Silver is used freely to describe silver toned beads made out of this zinc alloy, but these type of beads do not come from Tibet, and they do not contain any precious silver metal.)
Please note: These beads are sold by the manufacturers as lead-free, but I have no way of testing that claim. I do NOT recommend using metal beads in jewelry for children, or for anyone who might put jewelry in their mouths. (Small beads present a choking and swallowing hazard, and trace amounts of heavy metals that are perfectly harmless for adults can be dangerous for children, so let's play it safe!)
