This shell necklace is an ornament from one of the indigenous tribal groups from West Papua New Guinea. Shells were often used as both adornment and currency with these groups. The string/rope is handmade from a plant fiber. As with many items from the tribal groups of New Guinea, it is difficult to put an age on this piece. It is an interesting ethnographic artifact and can be used for display and can also be worn as a necklace. The diameter of the opening is just over 8 inches. The necklace came from an estate collection with no additional information.
The island of Papua New Guinea is divided. The Western side is a province of Indonesia and was created from the western portion of Papua province in 2003, initially under the name of Irian Jaya Barat, and was renamed Papua Barat (West Papua) in 2007.
