This traditional Papua New Guinea-style ceremonial shell ornament is a unique and culturally significant piece. Handcrafted from natural shells, probably a baler shell (Melo amphora), this original ornament reflects the rich cultural heritage of the Pacific Islands & Oceania. The multi-color design adds a vibrant touch to this intricately carved piece, making it a standout decorative item or a meaningful gift for special occasions such as bride-wealth ceremonies.
Made in Papua New Guinea, this shell ornament captures the essence of the region's traditional practices and artistry. The he large curved white/pearlescent element appears to be a section of baler shell (Melo shell, sometimes called Melo amphora) rather than the flatter crescent "kina" gold-lip pearl shell most people picture - baler shell has that thick, glossy, slightly curved-hook profile with visible growth-line striations, which matches what's in your photo. Ground and polished baler shell pectorals suspended from cowrie-shell straps are a documented ornament type from the Strickland-Bosavi border region of PNG's Western/Southern Highlands provinces - which includes the Biami/Bedamuni and their neighbors (Kaluli, Onabasulu, Gebusi)- used for bride price payments, ceremonial exchanges ("moka"), and status display by important men ("Big Men"). The two rows of small white cowrie shells strung on plaited bark/fiber cord that flank your pendant are a very typical pairing - cowries were themselves a secondary currency/adornment item, often combined with a pearl-shell centerpiece exactly like this. The two parallel cowrie rows joining at the shell is also a construction style consistent with genuine use-ornaments from that region, not the simplified single-strand designs common in tourist-market pieces.
At roughly 17 inches as measured, this is a substantial piece - consistent with a ceremonial pectoral meant to be worn hanging on the chest rather than a small trinket.
