Ibn Khordadhbeh, Book of Roads and Provinces, late ninth century AD.
Excavations of royal tombs near Silla's capital, Kumsong, or 'City of Gold' (modern Kyongju) have unearthed magnificent royal regalia in sheet gold, including crowns, belts, shoes, earrings, necklaces and vessels. This pair of gold ear-rings probably came from a tomb in the Kyongju area.
Both the custom of wearing earrings and the technique of granulation are thought have come to Korea through the Han colony at Nangnang (Lelang 108 BC - AD 313) in northern China. However, the Chinese wore glass earrings and it is thought that the Koreans introduced gold ones in the fourth century AD. They appear to have been worn with strings around the ear lobe.
