Animal teeth and shells are main components of the Neolithic necklace from Bonnières-sur-Seine. Among the materials that Neolithic people chose for jewelry, animal materials were particularly popular with the first Neolithic farmers in Yvelines. Even before the beginning of the Neolithic (around 5100 BC), the shell of the Spondylus shell from the Adriatic and Aegean Sea was valued for the production of rings and pearls. From the 5th millennium BC BC people preferred slate rings . Later, beads made from rock and bone materials were used.
