One of the most widespread forms of Melanesian jewelry is the kapkap, a disk-shaped ornament typically fashioned from the shell of the giant clam and overlain with a delicate filigree of turtle shell. Kapkap occur, or occurred, across much of the southwest Pacific, from coastal New Guinea eastward to the Santa Cruz Islands. Admiralty Islands artist were among the most prolific kapkap makers. Worn as head ornaments or pendants, kapkap in the Admiralties were primarily male ornaments, although women wore smaller examples in some areas. Most have geometric designs, although some forms incorporate figurative images. Some design elements may have had symbolic meaning, but it is conceivable that many were purely decorative.
