Lovely Dian Kingdom chalcedony “nipple bead” circa 400 BCE to 100 BCE, with “moonlike” translucence. These button like ornaments were unique to this culture, they were used in decorating bronze buckles, funeral shrouds as well as clothing and strung as beads. Quite rare these days- I haven’t seen a “fresh” pieces on market for several years. The Dian were a fierce and independent kingdom living in the vicinity of Dianchi Lake, Yunnan Province which chronologically paralleled the Warring States and Han Dynasties- this was eventually annexed by the Han Emperor Wudi in 109 BCE. Their bronze artifacts depicting hunting scenes indicate these people might have had a Scythian origin. This has two shallow chips on the side and inclusions- please view enlargements. D: 3.6cm/1.4in. Free shipping via Hong Kong Registered Airmail.
