A curious and characteristic jade artefact, known as _nbouet_ or _koindien_, is found among the natives of New Caledonia. This is a more or less circular disk of jade, with a cutting edge. In most cases this disk is attached through two perforations to a straight cylindrical handle, having a slit at the upper extremity into which the jade disk is introduced. The lower extremity has an ovoid termination, or else it is set in a cocoanut shell, usually covered with the integument of a pteropod. Attached are pendants of beautiful marine shells, and sometimes the cocoanut shell is filled with small pebbles so that it can be used as a rattle. These _nbouet_ were originally used as cleavers to cut up the dead bodies for the cannibalistic orgies, and this use seems to have been thought to impart a kind of talismanic virtue to the objects, for they eventually became insignia of the chiefs of the native tribes.[646] The ornament most highly prized by the natives of New Caledonia is a necklace of perforated jade beads. One of these necklaces, in the rich collection of Signor Giglioli, contains 122 jade beads, somewhat larger than peas; another necklace comprises eight beads alternating with small shells of the _oliva_, a species of mussel. As a pendant hangs an _oudip_, or slung-shot, of steatite.[647] Necklaces of this kind are called _peigha_ by the natives, and the high esteem in which they are held probably arises from their supposed talismanic powers. The jade ornaments or artefacts found in the neighboring Loyalty Islands have all been brought from New Caledonia, and we are told that so great was the value placed upon them that the natives of the Loyalty Islands often traded their young girls in exchange for objects made from the greatly coveted jade.
