This strand (167 beads, 55" long) was collected in Borneo in 1967 by a natural scientist who had a business supplying mineral and fossil specimens, but he also bought craft and money items. This was probably some family's heirloom strand.

My own experience is with beads from the Africa trade, and I recognize a few of the types, but am curious about the rest. Are there Chinese (or other non-European) beads here? It strikes me that the beads are smaller on average than those found in the Africa trade - the largest are barely over 10mm width. Is anyone familiar with heirloom beads from Borneo or nearby, and how does this compare as far as the size and mixture of types?
