Importance of Lane's Necklace

This symbolizes the link Sarah has with her dead sister, Lane. Sarah has carried Lane's necklace with her since Lane's death, but she trades it to a tinker for a violin for Bell and a button for James. The fact that she is willing to trade the necklace is a symbol of the importance Sarah places on the violin and the button. It is also a sign that she is ready to move past the deep grief she feels about Lane.
