Tibetans wore small bronze objects called Thogcha as amulets for protection and good fortune. Thogcha means 'sky-iron' and refers to the popular belief that they fall from the sky much like meteorites but fully formed into amulets of ritual significance.
Early contact with Central Asia, India, Mongolia and China influenced designs. Buddhist deities are popular themes but some types predate Buddhism in Tibet. Bronze age arrow points, parts of horse trappings, armor and bronze buckles are also considered variations of thogcha.
