These natural, semi-precious Moonstone plugs are so pretty! Moonstone was popular with the Romans, who thought it was formed out of moonlight. It arouses tender passion and is said to help all be more at peace. Moonstone soothes stress and anxiety and promotes emotional balance and gracefulness. PLEASE NOTE: As this is a natural product. Individual plugs will vary in appearance as a consequence. Also, while quite strong, it may break or chip if it is dropped.
