Love beads are one of the traditional accessories of hippies. They consist of one or more long strings of beads, frequently handmade, worn about the neck by both genders. The love bead trend probably evolved from the hippie fascination with non-Western cultures, such as those of India and Native America, which make common use of similar beads.
