AN ARCHAISTIC JADE DISC, BI, QING DYNASTY China, 18th century. Of circular form, carved on both sides around the central aperture with a pattern of small spiral bosses, encircled by a rope-twist band and an outer register of archaistic taotie masks above a neatly incised leiwen ground, the stone of faint pale celadon tone suddenly transforming to a chocolate brown on the lower third. Provenance: From an old Austrian private collection, acquired in China before 1952. Galerie Zacke, Vienna, Austria, June 2011. A private collector, acquired from the above, and thence by descent within the same family. Condition: Good condition with some wear and minor nicks and nibbles to the edges. Weight: 129.2 g Dimensions: Diameter 9.5 cm Auction result comparison: Compare with a "twin" bi disc at Sotheby's London in Fine Chinese Ceramics and Works of Art, 9 November 2011, lot 326, sold for GBP £25,000. Given that the old Austrian private collection, mentioned above, was divided between several heirs, it is well possible that this bi disc and the present lot were originally a pair. 仿古玉璧，清代 中國， 十八世紀。圓形，在中心孔周圍兩側刻有小螺旋狀凸起圖案，雷紋底，饕餮紋，淡淡青色玉石，一部份區域成焦糖色。 來源：奧地利私人老收藏，1952年前購於中國。奧地利維也納Zacke藝廊2011年。私人藏家購於上述藝廊，自此保存在同一家族至今。 品相：品相良好，一些磨損和輕微劃痕，邊緣有磕損。 重量：129.2 克 尺寸：直徑 9.5 厘米 拍賣結果比較：一件相似的玉璧于2011年11月9日倫敦蘇富比《中國陶瓷與工藝品》拍號 326, 成交價GBP £25,000。鑑於上述的奧地利私人老收藏被劃分為多個繼承人，因此這雙玉璧和現在的拍賣品原本可能是一對。
