This form of breast ornament is worn quite widely in the northern Solomon Islands of Vella Lavella and New Georgia. Its name in the local language at Tambatamba was recorded as saku. It is made of a tridacna clam shell ring which has been sawn out of a large clam shell. A backing of turtle shell provides an attachment for a fringe of coloured trade beads. Strung on the edge of this fringe is a border of teeth which are usually either cuscus (a type of possum), flying fox or dolphin. Larger trade beads and imported shirt buttons complete the three tassels. These shell rings and animal teeth represent wealth in Solomon Islands cultures, so the wearing of such an ornament indicates that the owner is a man of economic power and influence. This ornament was collected by Rev. A.H. Voyce of the Methodist Missionary Society of New Zealand who assembled a very large collection of artefacts in the Solomon Islands and New Guinea during the 1920s and 1930s. Much of the Voyce collection was purchased for Auckland Museum by Sir William Goodfellow in 1933.
