Jade tube

It is a kind of pendant on necklaces and a characteristic jade ornament in the Peinan Site in eastern Taiwan.

[1] The bar jades are polished into round pillar shapes, and then they are drilled from the two ends.

It is suspected that the drilling tools might be made of stone or metal, and there's no definite answer at this point.

As the long tubes were fragile, the fragments could be modified for re-use[1] As the tubes are mostly found to be on the neck of the skeletons, researchers suspected that they were pendants stranded on a necklace as a burial item or some specific purposes.

[1] The jade tubes are made of nephrite, or so-called Fengtian Jade, and the place of origin is primarily at the Fengtian Laonao Mountain in Shoufeng Township, Hualien County.
