Nila beads are small monochrome Islamic glass beads than can be found in colors ranging mostly from blue, green and white to yellow that are widespread in West Africa. They are also referred to as Indo-Pacific or Trade Winds beads, in reference to the winds that, for centuries, were used by the merchant ships bringing them from India. Large quantities have been found in sites along the river banks of the Niger river in Mali. Beads were often found buried in large quantities in clay pots, used as a form of currency. The word Nila came from the Sanskrit term for indigo.
As research and technology evolves, there is a greater ability to verify glass bead making by local manufacture in West Africa.
