The flawless material, superb hollowing and finish, and distinctive lipped rim, are all characteristics of Palace workshop production and allow for a possible Imperial attribution. Regardless of where it was made, however, it is an impeccably made, formal masterpiece unquestionably ranking amongst the greatest plain chalcedony bottles. This type of agate was apparently known as "Western agate" (see Moss, Graham, Tsang, A Treasury of Chinese Snuff Bottles, Vol. 2, Quartz, no. 258). The pattern of natural mottling here, accentuated by the extreme thinness of the walls, is suggestive of a continuous scene of mountain peaks rising above billowing clouds, evocative, perhaps, of the famous view from the peaks of Huangshan, in Anhui province.
