Note: Collared discs, sometimes named 'T'-section rings, are characterised by the raised edge or collar that circumscribes the inner wall of the central aperture. Like the David-Weill example, many collared discs are finely carved with series of concentric grooves. It has been suggested that discs of this type may have been worn as wrist or arm ornaments as the positioning of excavated examples from burial contexts demonstrates, see Howard Hansford, Chinese Carved Jades, London, 1968, pp. 71-73.

Twenty collared discs of different sizes and proportions were found among the jade artifacts discovered in the tomb of Fu Hao, ca. 1200 BC, at Anyang. They give an idea of the popularity of this disc form in late Shang dynasty, compare examples published in Yinxu yuqi, Beijing, 1982, figs. 6 and 7. At the same time, significant numbers of collared discs were discovered in contemporaneous sites in southern China, for example in Sanxingdui, Guanghan, Sichuan, and Xingan, Dayangzhou, Jiangxi, illustrating that this disc form also flourished far from the late Shang political centre in Henan, compare examples from Xingan Dayangzhou, illustrated in Shang dai Jiangnan - Jiangxi Xingan Dayangzhou chutu wenwu ziliao, Beijing, 2006, pp. 212-216. Jessica Rawson has called the appearance of collared discs a 'brief and perhaps exotic fashion' as they seem to disappear in the metropolitan areas conquered by the Western Zhou. It is not clear if the jade carvers of Anyang adopted the idea of making collared discs from Neolithic jades that had survived or if they were inspired by discs made in Southern China, see Jessica Rawson, Chinese Jade from the Neolithic to the Qing, London, 1995, pp. 164-165.

Examples in western collections formed in the 1920s and 1930s are numerous and include a collared disc of similar diameter and material from the Collection of Oscar Raphael, London, now in the Fitzwilliam Museum, Cambridge, illustrated in James C. S. Lin, The Immortal Stone. Chinese Jades from the Neolithic Period to the twentieth Century, Cambridge, 2009, p. 23, cat. 9. A disc from collection of HRH Gustav VI Adolf King of Sweden, is published in Nils Palmgren, Selected Chinese Antiquities from the Collection of Gustav Adolf Crown Prince of Sweden, Stockholm, 1948, no. 4; for six examples from the Sonnenschein Collection, see Alfred Salmony, Archaic Chinese Jades from the Edward and Louise B. Sonnenschein Collection, Chicago, 1952, pp. 40-43; two discs from the Winthrop Collection, are illustrated in Max Loehr and Louisa G. Fitzgerald Huber, Ancient Chinese Jades from the Grenville L. Winthrop Collection in the Fogg Art Museum, Harvard University, Cambridge, Massachusetts, 1975, nos. 101 and 102; and two examples from the Eumorfopoulos Collection and the Collection of Oscar Raphael, both now in the British Museum, London, published in Soame Jenyns, Chinese Archaic Jades in the British Museum, London, 1951, pls. IV and V. Several of these examples are said to have come from Anyang or Luoyang, Henan province.
