Zen trade beads are glass beads that served as currency in the African trade market from the 16th to the 20th centuries. Produced in Venice, Italy, these beads featured a black and white color scheme symbolizing yin and yang. Skilled craftsmanship was essential for their consistent size and shape. Today, Zen trade beads are highly valued by collectors.
