Calipan (also known as kalepan) is an ear ornament made of engraved mother-of-pearl, brass wires, and tiny beads. These earrings are worn by both women and men of the Bugkalot, also known as Ilongot. They feature a small disc of iridescent mother-of-pearl. The surface was engraved with a continuous sunburst motif, which was naturally blackened with ink or dye and formed a circle overlapping a cross design in the centre. The dangling fringes of the coiled brass wires, multi-colored beads, and mother-of-pear chips served as additional ornamentation, and a metal hoop was put into the disc's centre hole. Women wear it on their pierced lobes, and males wear it on the helixes of their ears. Since mother-of-pearl was gained through coastal trading, possessing a kalepan demonstrates social and financial capital, allowing a community or family members to engage in trade (Carlson, 2013). Furthermore, these earrings are a desirable personal ornament, suitable for use as a bride's wealth.
