|十九世紀 碧玉雙龍鈕璽Provenance:A French private collectionChristie's London, 11 May 2010, lot 77Durwin Tang Collection來源：法國私人舊藏佳士得倫敦，2010年5月11日，拍品編號77鄧德雍收藏Compare with a related Imperial spinach-green jade square seal, Daoguang, the seal-face carved Zhuwen, which was sold at Christie's London, 6 June 2000, lot 106. The inscription is identified as a posthumous title given to the Daoguang emperor's consort, Niuhu Lushi, who died in 1808. The title was bestowed on her following the accession to the throne by the Daoguang emperor. The spinach-green jade stone and style of carving would both appear to be similar to that of the present lot.道光孝穆成皇后（1781一1808）之碧玉雙龍紐璽可資參考，2000年6月6日售於佳士得倫敦，拍品編號106。孝穆成皇后姓鈕祜祿氏，其璽材質及龍鈕與本件拍品極似。
