Archaeological evidence indicates that people in Neolithic Europe were trading the shells of "S. gaederopus" to make bangles and other ornaments throughout much of the Neolithic period. The main use period appears to have been from around 5350 to 4200 BC. The shells were harvested from the Aegean Sea, but were transported far into the center of the continent. In the LBK and Lengyel cultures, "Spondylus" shells from the Aegean Sea were worked into bracelets and belt buckles. Over time styles changed with the middle neolithic favouring generally larger barrel-shaped beads and the late neolithic smaller flatter and disk shaped beads. Significant finds of jewelry made from Spondylus shells were made at the Varna Necropolis. During the late Neolithic the use of Spondylus in grave goods appears to have been limited to women and children.
