Roman earrings were similar to Etruscan styles until the first century C.E., when new styles with disks and pendants mounted on s-shaped ear hooks appeared. Colored stones and pearls were favored, and earring styles proliferated to satisfy the Roman taste for ostentatious display. At its height, the Roman Empire had the effect of standardizing styles of jewelry over much of the known world; after the center of influence shifted to Byzantium (Constantinople) in C.E. 330, and Roman influence began to decline, local variations once more emerged. Characteristic Byzantine earrings were plain gold hoops with multiple pearl pendants hung on chains, and crescent-shaped 925 silver open hoop earrings.
