Heirlooming and shell money beads in the Solomon Islands

Abstract

Strings of shell money made up of hundreds, if not thousands, of intensively worked shell beads have featured in the accounts of anthropologists of Melanesia for over a century, and large collections of these strings are to be found in major museum collections around the world. In the Solomon Islands, the tradition of their production continues to this day. Despite new strings still entering circulation, within villages in and around Malaita there are also older strings, either held communally or under tabu. Local wisdom states that some of these are around two hundred years old. The historical and anthropological literature also makes mention of heirloom shell money strings, although how long such strings may be curated and remain active in cultural life has never been quantified. Here, we investigate two large, complex shell money strings from the Solomon Islands, held in the collections of the Museum of Archaeology and Anthropology, University of Cambridge: one from Makira and the other from Nggela. Through direct accelerator mass spectrometry (AMS) radiocarbon dating of individual beads, we establish the restringing and combining of strings of different ages into new strings, as well as the maintenance in use of individual beads for up to two to three hundred years. This demonstrable case of the heirlooming of shell beads has repercussions for archaeology, and the potential cultural longevity of shell valuables such as these should be a consideration in interpretations.
