Hello. I have an heirloom pilaked Kalingga necklace from Lubuagan. It has several beads similar to these. Is the pilaked the Lubuagan version of the winayway? If I am not mistaken, the gold encrusted cylindrical bead is a "pang-ao", more common with the Ifugao. I was told that the Kalingga progressively add beads to an heirloom necklace as it is passed from generation to generation. That is if the beads have not been distributed to children. True?
