This pendulum necklace is approximately 20 inches in length not including the pendulum pendant. The Amethyst pendulum pendant is approximately 1.5 inches long & at the widest part approximately 20mm (just short a bit of an inch). There is a fauceted leaf like iolite bead (10mm long x 6mm wide x 2-3mm thick, a 6mm round amethyst bead, a round flat moonstone bead approximately 6mm x 2mm, a 6mm fauceted round opalite bead to accompany the pendulum. The chain is not sterling silver. There is no stamping that I can find to verify the type of metal. Amethyst Pendulum Necklace
