Each 5cm (2in) high. (3).遼 水晶雁柄杯一對Provenance:Acquired from Pao & Moltke, Toronto, in 2005A Canadian private collection來源：購於古董商Pao & Moltke，多倫多，2005年加拿大私人收藏The style and design of the present pair of rock crystal cup derives from the Khitan 'Spring Water and Autumn Mountain' themes of the Liao and Jin dynasties that remained popular in the Yuan dynasty. Compare a Yuan dynasty green jade 'wild goose' cup in the Qing Court Collection, illustrated by Yang Boda, Zhongzhongguo yuqi quanji, Shijiazhuang, 2005, p.481, no.183.兩件形制相同，皆為水晶整挖成來通杯形狀，底部則雕成回首大雁頭頸，用刀簡潔而自有神采。此對雁柄杯屬遼金時期春水秋山一類北方遊牧民族風格，一直延續到元代，可比較北京故宮博物院藏一件元代青玉雁柄杯形制設計與本對頗似，見楊伯達編，《中國玉器全集》，石家莊，2005年，卷中，頁481，編號183。
