These are beads found in Java and Borneo and are from the Early Classical Period, 750 - 1000 AD. They are considered to be Indo-Pacific beads. The opaque red color is the most prevalent color found and makes up much of this necklace. The striped beads in the center are made from black, white and opaque, red glass. These beads are from the same period as well.
The original Indo-Pacific bead-making techniques from Arikamedu, India, 1st Century BC, eventually were transferred to Funan, the first state in South East Asia, and then in 8th through 12th Century to the Srivijaya kingdom in South Sumatra. According to Peter Francis, by the time the Sailendra dynasty fell and the capital was moved to Jambi, Indo-Pacific beadmaking had disappeared in Southeast Asia.
