Unfortunately, many counterfeit Trollbeads items are difficult to detect by the untrained eye. However, most genuine Trollbeads products will be stamped with the following: Silver/Glass: 925S LAA Gold beads: 750 LAA Gold chains: 585 LAA Please be aware that silver and gold beads were first stamped in January 2006 and glass beads were first stamped in May 2008. Therefore, many genuine beads made before that time are not stamped.
