The gold earrings from the Kul-Oba burial-mound (near Kerch in the Crimea) were created by Athenian craftsmen in the 5th-4th centuries B.C. The fineness of the jeweller's work is astonishing: some details only become visible under a magnifying-glass. Each earring consists of a richly ornamented disc and a crescent-shaped pendant to which were attached chains with miniature amphorae at the ends. The joints are concealed by many-petalled rosettes of various sizes. The earrings are completely covered in a filigree pattern. The frame of the disc and many details are decorated with granulation and inset with coloured enamel. Small rosettes are placed around the large one, while in between them there are tiny figures of Nereids (sea-nymphs) riding on dolphins. They hold in their hands the sword, helmet and other accoutrements of a warrior that the Nereid Thetis is supposed to have given to her son Achilles.
