Common designs in jewellery sometimes extend beyond the geographical limits of a particular cultural area. The trade routes that connected the islands of the region also facilitated the flow of people and ideas. A well-known variation of this occurred in eastern Indonesia, where smiths from the tiny island of Ndao traveled all the way to Timor to ply their skills to the locals. This seasonal migration for work accounts for the similarity in jewellery forms among the two cultures. The Chinese were another group that adopted a similar practice. In this case, a collection of gold jewellery from across eastern Indonesia, Borneo, Central Sulawesi and even southern Philippines have been selected to illustrate the prevalence of the open oval form. A group of Central Javanese ornaments provides another perspective on this form from the distant past.
