Tapak Gajah are rings with a polygonal head seen in the jewellery of the Karo Batak, an indigenous people of Indonesia. It is thought that their unusual shape related to the magical diagrams on kuwari (amuletic arm disks, their diagrams possibly derived from Islamic traditions). For an hexagonal example dating to the 19th or 20th century see A. Richter and B. W. Carpenter, Gold Jewellery of the Indonesian Archipelago, Singapore, 2011, p. 385. Another octagonal example, catalogued as 19th century, is published in B. Chadour-Sampson and S. Hindman, Rings Around the World, NY, 2016, pp. 186-190. An octagonal gold Cincin tapak gajah is in the Musée du Quai Branly, Barbier Mueller Collection (inv. no. 70.2001.27.673). Such rings were believed to be apotropaic and were used in marriage ceremonies. No two rings are the same, with the diagram on the head of the ring being unique.
