Note: As Elinor Pearlstein states in her article, 'Salmony's Catalogue of the Sonnenschein Jades in the Light of Recent Finds' in Chinese Jade, Selected articles from Orientations 1983-1996, "…the inner zone contains a grid of faceted relief curls within hexagonal grooves. Variations on this pattern embellish discs found in tombs distributed over a very wide area including Hebei, Shandong, Jiangsu, Anhuei, Guangdong and Guangxi provinces. Such objects are often found in abundance in the tombs of local rulers enfeoffed by the Western Han Dynasty. The tombs of Liu Sheng (d.113BC) and Dou Wan in Mancheng in Hebei province and of Zhao Mo (d.122BC) of the Nanyue kingdom (203-111BC) in Guangzhou, Guangdong province, indicate this form's far flung distribution by the late 2nd Century BC."
